description: Identifying the true theory of dark matter depends crucially on accurately characterizing interactions of dark matter (DM) with other species. In the context of DM direct detection, we present a study of the prospects for correctly identifying the low-energy effective DM-nucleus scattering operators connected to UV-complete models of DM-quark interactions. We take a census of plausible UV-complete interaction models with different low-energy leading-order DM-nuclear responses. For each model (corresponding to different spin-, momentum-, and velocity-dependent responses), we create a large number of realizations of recoil-energy spectra, and use Bayesian methods to investigate the probability that experiments will be able to select the correct scattering model within a broad set of competing scattering hypotheses. We conclude that agnostic analysis of a strong signal (such as Generation-2 would see if cross sections are just below the current limits) seen on xenon and germanium experiments is likely to correctly identify momentum dependence of the dominant response, ruling out models with either "heavy" or "light" mediators, and enabling downselection of allowed models. However, a unique determination of the correct UV completion will critically depend on the availability of measurements from a wider variety of nuclear targets, including iodine or fluorine. We investigate how model-selection prospects depend on the energy window available for the analysis. In addition, we discuss accuracy of the DM particle mass determination under a wide variety of scattering models, and investigate impact of the specific types of particle-physics uncertainties on prospects for model selection.

The Concept of Habit and the Regularities of Social Structure
Creators: name: Crossley, Nick
Publisher: name: Phenomenology and Mind
Year: 2016

description: In this paper I discuss the concept of habit from a sociological point of view. My aim, in part, is to consider the ways in which sociologists and social philosophers could use and have used ‘habit’ in their analyses and explanations. In particular the concept of habit can contribute to our understanding and explanation of the behavioural regularities involved in social structure. In addition, however, I am interested in the limitations of the concept of habit, within a sociological context, when compared against other concepts which are used to do similar work. In particular I contrast the concept of habit with the concepts of ‘rule’ and ‘convention’, drawing out the strengths that it has relative to those competing concepts but also identifying important aspects of behavioural regularity which they bring to light and which habit ignores. In the conclusion to the paper I consider ways in which these various concepts might overlap and might be used in conjuction with one another.

Spot evolution on the red giant star XX Triangulum. A starspot-decay analysis based on time-series Doppler imaging

description: Solar spots appear to decay linearly proportional to their size. The decay rate of solar spots is directly related to magnetic diffusivity, which itself is a key quantity for the length of a magnetic-activity cycle. Is a linear spot decay also seen on other stars, and is this in agreement with the large range of solar and stellar activity cycle lengths? We investigate the evolution of starspots on the rapidly-rotating ($P_{\rm rot}$ $\approx$ 24 d) K0 giant XX Tri, using consecutive time-series Doppler images. Our aim is to obtain a well-sampled movie of the stellar surface over many years, and thereby detect and quantify a starspot decay law for further comparison with the Sun. We obtained continuous high-resolution and phase-resolved spectroscopy with the 1.2-m robotic STELLA telescope on Tenerife over six years. For each observing season, we obtained between 5 to 7 independent Doppler images, one per stellar rotation, making up a total of 36 maps. To quantify starspot area decay and growth, we match the observed images with simplified spot models based on a Monte Carlo approach. It is shown that the surface of XX Tri is covered with large high-latitude and even polar spots and with occasional small equatorial spots. Just over the course of six years, we see a systematically changing spot distribution with various timescales and morphology, such as spot fragmentation and spot merging as well as spot decay and formation. An average linear decay of $D$ = $-$0.022 $\pm$ 0.002 SH/day is inferred. We found evidence of an active longitude in phase toward the (unseen) companion star. Furthermore, we detect a weak solar-like differential rotation with a surface shear of $α$ = 0.016 $\pm$ 0.003. From the decay rate, we determine a turbulent diffusivity of $η_T$ = (6.3 $\pm$ 0.5) $\times$ 10$^{14}$ cm$^2$/s and predict a magnetic activity cycle of $\approx$ 26 $\pm$ 6 years.
title: Del Pezzo fibrations and rank 3 Cox rings
Creators: name: Ahmadinezhad, Hamid
Publisher: name: University of Kent
Year: 2022

description: One possible output of the minimal model program is a Mori fibre space. These varieties in 3 dimensions are Fano varieties, del Pezzo fibrations and conic bundles. Uniqueness of this output, the so-called rigidity of a Mori fibre space, is a question which arises naturally. In many cases, it has been proven for a general Fano 3-fold to be rigid. Del Pezzo fibrations over the rational curve have been studied in higher degrees and consequently it is known that if deg > 3 then the del Pezzo fibration is nonrigid. The goal of this thesis is to study rigidity and nonrigidity of low degree del Pezzo fibrations. We give a construction of these objects and classify the nonrigid ones whose link to the other model is obtained by the ambient space. This, in particular, provides many examples of nonrigid degree 2 del Pezzo fibrations which are not necessarily smooth. It is known that the study of rigidity for degree 3 del Pezzo fibrations is subject to consideration of Corti-KoMr stability condition. A first attempt to generalise this stability notion for lower degree fibrations is given in this thesis. The relation between these stability conditions and Sarkisov program is also studied in an explicit way. This requires techniques of working with rank 3 Cox rings which we develop. In particular, the notion of well-formedness for Cox rings is introduced as a generalisation of well- formedness of weighted projective spaces. We also construct families of cubic surface fibration in dimension 4 and study their nonrigidity in a similar way.
Phenomenological Habitus and Social Creativity
Creators: name: Kokoszka, Valérie
Publisher: name: Phenomenology and Mind
Year: 2016

description: How is social creativity linked to habitual dispositions? This paper critiques Bourdieu’s answer to this question, which is related to his theory of habitus, against the background of its phenomenological evidences. His concept of habitual dispositions seems to be linked both to an internalisation of the performativity of habits as a form of Kantian schematism (in Husserlian terms: ‘noetization’), and to a static concept of the social environment, which is never analysed in its own dynamic structural relation to the life of the bearer of habits. Through the genetic-phenomenological distinction between habits as noetic dispositions and types as noematic schemes, the paper seeks to show that the social environment cannot be presupposed as a given field of social objectivities and norms that are stabilized by internalized habitual dispositions, but should instead be seen as an enactively framed habitat. When we further distinguish between passive and active habitualities, their intertwining comes to the fore, showing how in taking a position in relation to its own cultural environment the subject finds in the hiatus between disposition and the disposed leeway for a relative framework of spontaneity and personal cultivation, a space allowing for individual and, ultimately, social creativity that is absent from Bourdieu’s account.

description: We consider the Laplace operator in the exterior of a compact set in the plane, subject to Robin boundary conditions. If the boundary coupling is sufficiently negative, there are at least two discrete eigenvalues below the essential spectrum. We state a general conjecture that the second eigenvalue is maximised by the exterior of a disk under isochoric or isoperimetric constraints. We prove an isoelastic version of the conjecture for the exterior of convex domains. Finally, we establish a monotonicity result for the second eigenvalue under the condition that the compact set is strictly star-shaped and centrally symmetric.

Episodic and Non-Episodic Intentionality: on the Constitutive Function of the Epistemic Habitualities of Knowledge and Belief in Edmund Husserl
Creators: name: Sowa, Rochus
Publisher: name: Phenomenology and Mind
Year: 2016

description: Husserl introduced empty intentions into the framework of static phenomenology in order to render intelligible the fact that we are conscious of whole things in perception despite the fact that they are always presented to us only from one side and we don’t have any imaginative or symbolic representation of all their unseen properties. The article shows that this conception of empty intention is a misconception and that the emptiness that is constitutive for the givenness of whole things in perception is due not to empty intentions but to intentional habitualities, especially to habitual beliefs. These beliefs make up the empty horizons through which we have consciousness of whole things and of the world as a whole. This solution is offered by Husserl in the framework of his genetic phenomenology. Referring to some of Husserl’s genetic pronouncements, the article investigates the constitutive role of two forms of habitual beliefs: beliefs which stem from one’s own experiences and insights and beliefs that stem from other’s experiences or insights and are taken over in good faith. Special attention is paid to this second form of habitual beliefs for the constitution of the world; it is argued that the world-horizon is basically made up of habitual beliefs of this second form.

description: The goal of this paper is to prove rigorous results for the behavior of genealogies in a one-dimensional long range biased voter model introduced by Hallatschek and Nelson [25]. The first step, which is easily accomplished using results of Mueller and Tribe [38], is to show that when space and time are rescaled correctly, our biased voter model converges to a Wright-Fisher SPDE. A simple extension of a result of Durrett and Restrepo [18] then shows that the dual branching coalescing random walk converges to a branching Brownian motion in which particles coalesce after an exponentially distributed amount of intersection local time. Brunet et al. [8] have conjectured that genealogies in models of this type are described by the Bolthausen-Sznitman coalescent, see [39]. However, in the model we study there are no simultaneous coalescences. Our third and most significant result concerns "tracer dynamics" in which some of the initial particles in the biased voter model are labeled. We show that the joint distribution of the labeled and unlabeled particles converges to the solution of a system of stochastic partial differential equations. A new duality equation that generalizes the one Shiga [44] developed for the Wright-Fisher SPDE is the key to the proof of that result.

On Scheler’s Metaphysics of Love: an Appraisal
Creators: name: Zhok, Andrea
Publisher: name: Phenomenology and Mind
Year: 2016

description: In the following pages we are going to briefly recollect some of Scheler’s main arguments concerning the status of “affective life” and to try a sympathetic appraisal of the bearing of these theses. After resuming Scheler’s assessment of love and showing its conceptual connections with intentionality, spiritual values and sensuous corporeality, we shall sketch an account of the ontological and axiological role of love. Love turns out to be interpretable as a pervasive drive that shapes both natural and cultural history, while history, in its most comprehensive sense, is not viewed either as sheer contingency or as teleology, but rather as an exploratory cosmological venture.

description: The paper reconstructs, develops and discusses Scheler’s Bildung theory to highlight its relevance for educational philosophy. First, we point out that a personality flourishes through a process of progressive individuation which is modulated by affective maturation and promoted by the encounter with an exemplarity. Then, in order to avoid some limits of Scheler’s realism, we suggest rethinking these theses in the light of a new epistemological position (relational enactivism).

Scheler’s Foundation of Ethics
Creators: name: Piazza, Anna
Publisher: name: Phenomenology and Mind
Year: 2016

description: In this paper I would like to deal with Scheler’s emotional ethics and its relationship with a possible ontological foundation. I want to address the theme of values and acts, asking whether they are rooted in being or whether they possess their status autonomously, and where they obtain their legality and consistency from. I will face first of all Scheler’s original discovery of the special status of value as intentional object and the correlated human capacity of grasping it, realizing the corrected order of values and fulfilling the “moral good”. In the end, as I will underline how Scheler’s gain lies in the avoidance of reducing the foundation of ethics to a transcendental deduction or to an inductive-empirical method, I will stress the problem of his personalistic ethic, in the attempt to hand over to the person the whole discretion of letting values emerge and affirm in the history.

description: The structure of membrane-active peptides and their interaction with lipid bilayers can be studied in oriented lipid membranes deposited on solid substrates. Such systems are desirable for a number of surface-sensitive techniques. Here we focus on structural characterization by x-ray and neutron reflectivity and give an account of recent progress in sample preparation and measurements. We show that the degree of mesoscopic disorder in the films can significantly influence the scattering curves. Static defects should be minimized by optimization of the preparation techniques and their presence must be taken into account in the modelling. Examples are given for alamethicin and magainin in bilayers of different phosphocholines.
Governing Emotions. Husserl and Personal Vocation
Creators: name: Venier, Veniero
Publisher: name: Phenomenology and Mind
Year: 2016

description: Husserl’s work contains a central ethical question: the creation of a personal order in relation to values and their cognition. An order in which the fundamental structure of the actual idea of a person is revealed: that of being the essential tie between feeling, motivation of volition and logical-argumentative coherence. This value is felt emotionally but the true understanding of the value only occurs in rational choice, when feeling is concretely translated into value; only when the intellect recognises what has become manifest in emotional acts, does the value actually become such and can act as a motivation for rational action. As its consequent result, the ability of evaluation makes use of the understanding of the meaning of the personal unit: the actual faculty of self-evaluation and selfdetermination, of self-regulation towards the good and right. It is the theme of centrality that the process of self-formation as the education of the self assumes in Husserlian ethical discourse as the capacity to relate the general norm to one’s own order of values, to one’s best, that corresponds to the very question of personal vocation according to Husserl. This is certainly an individual ideal but at the same time, also a social ideal since the actual life of a community can take on the form of an ethical life characterised by collective renewal, but only on the basis of the capacity for individual renewal.

description: We study the formation of local magnetic moments and magnetic hyperfine fields at an \textit{s-p} impurity diluted in intermetallic Laves phases compounds $R$Ni$_{2}$ ($R$ = Nd, Sm, Gd, Tb, Dy) at finite temperatures. We start with a clean host and later the impurity is introduced. The host has two-coupled ($R$ and Ni) sublattice Hubbard Hamiltonians but the Ni sublattice can be disregarded because its $\textit{d}$ band, being full, is magnetically ineffective. Also, the effect of the $\textit{4f}$ electrons of $R$ is represented by a polarization of the \textit{d} band that would be produced by the $\textit{4f}$ magnetic field.This leaves us with a lattice of \textit{effective} rare earth \textit{R}-ions with only \textit{d} electrons. For the \textit{dd} electronic interaction we use the Hubbard-Stratonovich identity in a functional integral approach in the static saddle point approximation.

In addition, if the Stokes system, instead Navier-Stokes system, is considered for the fluid equation, we prove that bounded weak solutions exist globally in time.

description: Purpose: We present a new morphometric measure of trabecular bone microarchitecture, called mean node strength (NdStr), which is part of a newly developed approach called long range node-strut analysis. Our general aim is to describe and quantify the apparent "latticelike" microarchitecture of the trabecular bone network. Methods: Similar in some ways to the topological node-strut analysis introduced by Garrahan et al. [J. Microsc. 142, 341-349 (1986)], our method is distinguished by an emphasis on long-range trabecular connectivity. Thus, while the topological classification of a pixel (after skeletonization) as a node, strut, or terminus, can be determined from the 3x3 neighborhood of that pixel, our method, which does not involve skeletonization, takes into account a much larger neighborhood. In addition, rather than giving a discrete classification of each pixel as a node, strut, or terminus, our method produces a continuous variable, node strength. The node strength is averaged over a region of interest to produce the mean node strength of the region. Results: We have applied our long range node-strut analysis to a set of 26 high-resolution ... The Nd/Tm ratios were computed using traditional histomorphometry performed on bone biopsies obtained at the same location as the pQCT scans. Conclusions: The newly introduced morphometric measure allows a quantitative assessment of the long-range connectivity of trabecular bone. One advantage of this method is that it is based on pQCT images that can be obtained noninvasively from patients, i.e., without having to obtain a bone biopsy from the patient.

This is done via the gauge unfixing technique, which serves as the exposition in the context of the radial gauge.

The canonical structure of the theory is analyzed.

description: It is shown that every algebraic quantum field theory has an underlying functorial field theory which is defined on a suitable globally hyperbolic Lorentzian bordism pseudo-category. This means that globally hyperbolic Lorentzian bordisms between Cauchy surfaces arise naturally in the context of algebraic quantum field theory. The underlying functorial field theory encodes the time evolution of the original theory, but not its spatially local structure. As an illustrative application of these results, the algebraic and functorial descriptions of a free scalar quantum field are compared in detail.

Local entanglement of electrons in 1D hydrogen molecule

Publisher: name: arXiv
Year: 2023
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: The quantum entanglement entropy of the electrons in one-dimensional hydrogen molecule is quantified locally using an appropriate partitioning of the two-dimensional configuration space. Both the global and the local entanglement entropy exhibit a monotonic increase when increasing the inter-nuclear distance, while the local entropy remains peaked at the middle between the nuclei with its width decreasing. Our findings show that at the inter-nuclear distance where stable hydrogen molecule is formed, the quantum entropy shows no peculiarity thus indicating that the entropy and the energy measures display different sensitivity with respect to the interaction between the two identical electrons involved. One possible explanation is that the calculation of the quantum entropy does not account explicitly for the distance between the nuclei, which contrasts to the total energy calculation where the energy minimum depends decisively on that distance. The numerically exact and the time-dependent quantum Monte Carlo calculations show close results.
Not Kant vs. Scheler, but either Kant or Scheler. From Construction to Foundation of Ethics
Creators: name: Sanchini, Virginia
Publisher: name: Phenomenology and Mind
Year: 2016

description: Scheler’s moral theory is often presented as a critical reaction to Kantian formalism. The majority of contributions on this topic deals with Scheler’s proposal of an a priori material ethics in contrast with the a priori formal ethics developed by Kant, or with the critical analysis of the eight prejudices ascribed by Scheler to Kant. A very few of them, however, explore their respective foundational attempts to see why such a conflict actually arises. This paper addresses exactly the foundational issue, trying to fulfill this empty space in the literature. In particular, by briefly investigating the third section of the Groundwork of the Metaphysics of Moral and the doctrine of the Fact of Reason depicted by Kant in the second Critique on the one hand and the phenomenological theory of values elaborated by Scheler on the other hand, it will be shown that the disagreement between the two authors should not be ascribed to a real incompatibility, but rather to a different way of conceiving what the foundation of ethics actually is.

description: When pulling a probe particle in a many-particle system with fixed velocity, the probe's effective friction, defined as average pulling force over its velocity, $γ_{eff}:=\langle F_{ex}\rangle/u$, first keeps constant (linear response), then decreases (thinning) and finally increases (thickening). We propose a three-time-scales picture (TTSP) to unify thinning and thickening behaviour. The points of the TTSP are that there are three distinct time scales of bath particles: diffusion, damping, and single probe-bath (P-B) collision; the dominating time scales, which are controlled by the pulling velocity, determine the behaviour of the probe's friction. We confirm the TTSP by Langevin dynamics simulation. Microscopically, we find that for computing the effective friction, Maxwellian distribution of bath particles' velocities works in low Reynolds number (Re) but fails in high Re. It can be understood based on the microscopic mechanism of thickening obtained in the $T=0$ limit. Based on the TTSP, we explain different thinning and thickening observations in some earlier literature.

description: In recent years, there has been an intense interest in understanding the microscopic mechanism of thermally induced magnetization switching driven by a femtosecond laser pulse. Most of the effort has been dedicated to periodic crystalline structures while the amorphous counterparts have been less studied. By using a multiscale approach, i.e. first-principles density functional theory combined with atomistic spin dynamics, we report here on the very intricate structural and magnetic nature of amorphous Gd-Fe alloys for a wide range of Gd and Fe atomic concentrations at the nanoscale level. Both structural and dynamical properties of Gd-Fe alloys reported in this work are in good agreement with previous experiments. We calculated the dynamic behavior of homogeneous and inhomogeneous amorphous Gd-Fe alloys and their response under the influence of a femtosecond laser pulse. In the homogeneous sample, the Fe sublattice switches its magnetization before the Gd one. However, the temporal sequence of the switching of the two sublattices is reversed in the inhomogeneous sample. We propose a possible explanation based on a mechanism driven by a combination of the Dzyaloshiskii-Moriya interaction and exchange frustration, modeled by an antiferromagnetic second-neighbour exchange interaction between Gd atoms in the Gd-rich region. We also report on the influence of laser fluence and damping effects in the all-thermal switching.

The Case for Participatory Realism in Scheler’s Ethics
Creators: name: Hackett, J. Edward
Publisher: name: Phenomenology and Mind
Year: 2016

description: might one ask how phenomenological commitments relate to value ontology. Consider Phil Blosser’s words: …the chief defect of Scheler’s phenomenology, like all philosophies of value, was the weakness of his treatment of the ontology of values. The insufficient development of this fundamental aspect of Value Theory has left it especially vulnerable in a philosophical climate that has been distinguished, since the 1930s, by the major “growth industry” of Heideggerian ontology, making this appear probably the most critical defect of Scheler’s Formalismus*. In this paper, I will argue that being-an-act (Akt-sein) will provide us with insight into Scheler’s value ontology. My efforts rest on two fundamental premises: showing how Scheler’s phenomenology opens up into ontology, and how being-an-act is understood with that opening in mind in Scheler’s Idealism and Realism essay. In Part 1, I argue how phenomenologists can reify one-side of the intentional relation and generate different ontologies, and these thoughts underlie the opening of the Idealism and Realism. In Part 2, I show how being-an-act opens up into ontology. In Part 3, I reveal how the participatory sense of realism is shown in the intentional relation, and how persons participate in value. In the final section, the “ontologization” of the intentional relation is found in the problem of reality.

Rules of Distribution and the Concept of “Egalitarianism” in Felix Oppenheim. Towards Understanding Distribution
Creators: name: Loddo, Olimpia G.
Publisher: name: Phenomenology and Mind
Year: 2016

description: The political philosopher Felix Oppenheim reconstructs a descriptive concept of “egalitarianism” on the basis of rules of distribution. The present paper reverses Oppenheim’s perspective by analyzing the role of distributives rules and of “egalitarianism” towards understanding distribution. In what measure does the concept of “egalitarianism” help us to understand distribution? Is it possible to understand a distribution only on the basis of descriptive concepts?

description: In light of recent measurements suggesting potential lepton flavor universality violations in semileptonic decays at collider experiments, this article provides a concise study of tree- and loop-level $B$-hadron semileptonic decays, $b \to c l ν_l$ and $b \to s l^+ l^-$. We provide predictions for lepton flavor violating observables, $\mathcal{R}_{J/ψ}$ and $\mathcal{R}_{η_c}$, across the entire $q^2$ range. Our study employs the Relativistic Independent Quark Model (RIQM), highlighting a model-dependent approach to these observables. We compare our model's predictions with existing lattice predictions, demonstrating the strong applicability of the RIQM framework in describing $B_c$ decays. Additionally, we reassess global averages for $\mathcal{R}_{D(D^*)}$ and $\mathcal{R}_{K(K^*)}$ in semileptonic transitions. With the upcoming experimental upgrades and the anticipated Run 3 data on $B_c$ meson decays, rapid confirmation of these quantities could indicate significant evidence of physics beyond the Standard Model, thereby opening new pathways for understanding the complex flavor dynamics in $B$ meson decays.

description: Wearable cameras offer a hands-free way to record egocentric images of daily experiences, where social events are of special interest. The first step towards detection of social events is to track the appearance of multiple persons involved in it. In this paper, we propose a novel method to find correspondences of multiple faces in low temporal resolution egocentric videos acquired through a wearable camera. This kind of photo-stream imposes additional challenges to the multi-tracking problem with respect to conventional videos. Due to the free motion of the camera and to its low temporal resolution, abrupt changes in the field of view, in illumination condition and in the target location are highly frequent. To overcome such difficulties, we propose a multi-face tracking method that generates a set of tracklets through finding correspondences along the whole sequence for each detected face and takes advantage of the tracklets redundancy to deal with unreliable ones. Similar tracklets are grouped into the so called extended bag-of-tracklets (eBoT), which is aimed to correspond to a specific person. Finally, a prototype tracklet is extracted for each eBoT, where the occurred occlusions are estimated by relying on a new measure of confidence. We validated our approach over an extensive dataset of egocentric photo-streams and compared it to state of the art methods, demonstrating its effectiveness and robustness.

A Nonabelian Particle-Vortex Duality
Creators: name: Murugan, Jeff

Publisher: name: arXiv
Year: 2015
Subjects: subject: High Energy Physics - Theory (hep-th)

description: We define a nonabelian particle-vortex duality as a $3-$dimensional analogue of the usual $2-$dimensional worldsheet nonabelian T-duality. The transformation is defined in the presence of a global $SU(2)$ symmetry and, although derived from a string theoretic setting, we formulate it generally. We then apply it to so-called "semilocal strings" in an $SU(2)_{G}\times U(1)_{L}$ gauge theory, originally discovered in the context of cosmic string physics.

description: We derive a semi-classical formula for computing the spectrum of bound states made of Majorana fermions in a generic non-integrable 2d quantum field theory with a set of degenerate vacua. We illustrate the application of the formula in a series of cases, including an asymmetric well potential where the spectra of bosons and fermions may have some curious features. We also discuss the merging of fermionic and bosonic spectra in the presence of supersymmetry. Finally, we use the semi-classical formula to analyse the evolution of the particle spectra in a class of non-integrable supersymmetry models.

Psychophysics Phenomenologized? Sensation and Decision in Visual Motion Perception
Creators: name: Gregori Grgic, Regina
name: De’Sperati, Claudio
Publisher: name: Phenomenology and Mind
Year: 2016

description: Experimental phenomenology and psychophysics are two rather different approaches to the study of perception, and rely on first-person descriptions and third-person measurements of the percept, respectively. Yet, a common ground may be found in the original goal, shared by both approaches, of addressing the conscious dimension of perception. Here we argue that, despite being objective and quantitatively-oriented, psychophysics can, with some cautions, recover certain simple subjective aspects of conscious perception. Building upon the results of a motion perception experiment, we show how to transform the ratings of subjective visibility into a well-known index of objective discriminability in perceptual decisions (d’). We found that, once all factors are equated, motion discrimination is superior to motion detection, as measured as perceptual decisions; in turn, motion detection is superior to subjective motion visibility. This finding strengthens our previous suggestion that, under uncertainty conditions, perceptual decisions can be taken before the conscious percept is fully stabilized, and suggests that some simple sensations can be reliably captured by objective “currency” through an open-minded quantitative approach. Our perspective may be regarded as an attempt to “phenomenologize psychophysics”.

Evidence for broken Galilean invariance at the quantum spin Hall edge

description: We study transport properties of the helical edge channels of a quantum spin Hall (QSH) insulator, in the presence of electron-electron interactions and weak, local Rashba spin-orbit coupling. The combination of the two allows for inelastic backscattering that does not break time-reversal symmetry (TRS), resulting in interaction-dependent power law corrections to the conductance. Here, we use a non-equilibrium Keldysh formalism to describe the situation of a long, one-dimensional edge channel coupled to external reservoirs, where the applied bias is the leading energy scale. By calculating explicitly the corrections to the conductance up to fourth order of the impurity strength, we analyse correlated single- and two-particle backscattering processes on a microscopic level. Interestingly, we show that the modeling of the leads together with the breaking of Galilean invariance has important consequences on the transport properties. Such breaking occurs, because the Galilean invariance of the bulk spectrum transforms into an emergent Lorentz invariance of the edge spectrum. With this broken Galilean invariance at the QSH edge, we find a contribution to single particle backscattering with a very low power scaling, while in the presence of Galilean invariance the leading contribution would be due to correlated two-particle backscattering only. This difference is further reflected in different values of the Fano factor of the shot noise, an experimentally observable quantity. The described behaviour is specific to the Rashba scatterer, and does not occur in the case of backscattering off a time-reversal breaking, magnetic impurity.
