Interconnectedness : affect, media theory, and the subject of emotion in nineteenth century nature poetry (Wordsworth, Dickinson, and Keats)
Creators: name: Rubel, William Ilan
Publisher: name: University of British Columbia
Year: 2009

description: My focus in reading William Wordsworth and Emily Dickinson is on the links among sensation, emotion, and subjectivity. I argue that nineteenth century nature poets challenged ideologically bounded agency, as constructed in political and religious discourses, in an experiential turn to affect that shifted the weight of attention from intellect to sensation. This modulation, from discursive to somatic attention, shifted the terms of political agency and the contexts for imagining individual freedom. Though both nineteenth century nature poets and current media theorists share a common source thread in the affective philosophy of Baruch Spinoza, they address opposite sides of the spectrum of the potential of affect. Where the nineteenth century nature poet sees an opportunity to “counteract” the “degrading thirst after outrageous stimulation” and “extend the domain of the sensible,” the media theorist forewarns of an infiltration of information into biological life (‘bioinformatics’) by affective rather than discursive strategies, and of the “real subsumption” of biological subjects. In both turns to affect, the bounded agent proves either more inter-relational or more serial than in received conceptions of the liberal enlightened humanist subject. For the Romantic nature poet, bounded agency proves relational in the relaxation of the discursive center into sensation. For the media theorist, bounded agency proves serial (a product of “machinic assemblage” ) in the breakdown of categorical divisions between life and information. Pivotal to my argument is that in the Wordsworthian view, the turn to affect (exposure to the sensory impingements of natural phenomena and bodily emotion) has deconditioning effects, in stark contrast to current media theory, which notes affect’s creative potential but stresses its availability for biomediation and bioinformatics: Foucauldian “biopower.” Reading key texts by Wordsworth, including Preface to Lyrical Ballads (PLB), Tintern Abbey, The Prelude, and The Excursion, I consider the philosophical exploration of affect theory and political agency in Massumi, Sedgwick, Noonan, Braidotti, Agamben, Clough, Deleuze and Latour; the cognitive theories of Verela, Johnson, and Damasio; the radical science of Sheldrake and Bohm; and the commentary of literary critics, notably M.H. Abrams and John Beer, on Wordsworth’s sense of Being and consciousness.

description: Background: Asthma prevalence is high (> 10%) in developed countries, and though data for most of Africa is still missing, rates are rising in developing countries as they grow more westernised. Asthma is the 14th most important chronic disease in the world in terms of the prevalence, extent, and duration of disability, affecting 334 million individuals of all ages. The prevalence in Africa has been reported ranging from 18% in Kenya to 20% in South Africa. We investigated the prevalence of asthma in school children in Gaborone, Botswana. Methods: This was a descriptive cross-sectional research. The ISAAC approach was employed. A proportionate size random sample of two age groups of children (13-14 year olds and 6-7 year olds) was enrolled in ten schools in a systematic manner. A table of random numbers was used to choose the schools. A minimum sample of 924 individuals (462 from each group) was sufficient to achieve a precision of 3% around our estimated prevalence of asthma of 10% with 95% confidence, assuming a 20% non-response rate. The International study of Asthma and Allergies in Children (ISAAC) questionnaire was used to collect information. In accordance with the ISAAC criteria, Asthma was defined as wheezing in the previous 12 months. Data was captured in microsoft excel and analysed using SPSS version 23. Results: Asthma (wheezing in the previous 12 months) was present in 16.5% (194/1175). The prevalence of asthma (wheezing in the previous 12 months) was 15.9% among 6-7 year olds and 16.8% among 13-14 year olds. The prevalence of school type in private schools was 22.3% versus 14.5% in public schools. More severe asthma was associated with older children, 13 -14 years. The older children reported more limited speech due to wheezing (OR= 2.0, 95% CI =1.034, 3.9, p-value=0.043), ever had asthma (OR= 1.5, 95% CI=1.031, 2.3, p-value=0.034) and wheezing during exercise (OR=3.4, 95% CI= 2.5, 4.9, p-value= <0.001) compared to the younger children 6-7 years. Private school students had more wheezing symptoms.. They were more likely to have ever wheezed (OR=2.2, .95% CI=1.7,2.9, p-value < 0.0001), wheezed in the previous twelve months (have asthma) (OR=1.7,95%CI=1.2,2.4, p-value = 0.001), ever had asthma (OR=2.4, 95% CI=1.7,3.5, p-value<0.0001), and wheezed during exercise (OR=1.8, 95% CI=1.4,2.4, p-value < 0.0001). Conclusion: Asthma is very common among school children in Gaborone, Botswana, with older children having more severe asthma symptoms. When compared to public schools, private schools had a higher prevalence of asthma. In Botswana, more research is needed to examine the prevalence of asthma in rural and urban areas.

description: Quantum gas systems provide a unique experimental platform to study a fundamental paradigm of quantum many-body physics: the crossover between Bose-Einstein condensed (BEC) molecular pairs and Bardeen Cooper Schrieffer (BCS) superfluidity. Some studies have considered quantum gas samples confined in optical lattices, however, focusing on the case, when only the lowest Bloch band is populated, such that orbital degrees of freedom are excluded. In this work, for the first time, ultracold Feshbach molecules of fermionic $^{40}K$ atoms are selectively prepared in the second Bloch band of an optical square lattice, covering a wide range of interaction strengths including the regime of unitarity. Binding energies and band relaxation dynamics are measured by means of a method resembling mass spectrometry. The longest lifetimes arise for strongly interacting Feshbach molecules at the onset of unitarity with values around 300 ms for the lowest band and 100 ms for the second band. In the case of strong confinement in a deep lattice potential, we observe bound dimers also for negative values of the s-wave scattering length, extending previous findings for molecules in the lowest band. Our work prepares the stage for orbital BEC-BCS crossover physics.

description: We review some recent results on entanglement in the Quantum Spherical Model (QSM). The focus lays on the physical results rather than the mathematical details. Specifically, we study several entanglement-related quantities, such asentanglement entropies, and logarithmic negativity, in the presence of quantum and classical critical points, and in magnetically ordered phases. We consider both the short as well as the long-range QSM. The study of entanglement properties of the QSM is feasible because the model is mappable to a Gaussian system in any dimension. Despite this fact the QSM is an ideal theoretical laboratory to investigate a wide variety of physical scenarios, such as non mean field criticality, the effect of long-range interactions, the interplay between finite-temperature fluctuations and genuine quantum ones.

description: We report preliminary results concerning the detailed chemical composition of metal poor stars belonging to close ultra-faint dwarf galaxies (hereafter UfDSphs). The abundances have been determined thanks to spectra obtained with X-Shooter, a high efficiency spectrograph installed on one of the ESO VLT units. The sample of ultra-faint dwarf spheroidal stars have abundance ratios slightly lower to what is measured in field halo star of the same metallicity.We did not find extreme abundances in our Hercules stars as the one found by Koch for his 2 Hercules stars. The synthesis of the neutron capture elements Ba and Sr seems to originate from the same nucleosynthetic process in operation during the early stages of the galactic evolution.

description: Neutral particles in the plasma edge of fusion devices based on magnetic confinement are described by a transient kinetic equation incorporating ionization, recombination, and charge-exchange collisions. In charge-exchange dominated regimes, the neutral particle velocity distribution approaches the drifting Maxwellian defined by the mean velocity and temperature of the plasma. This enables model order reduction from the kinetic equation to approximate fluid models. We derive transient fluid models consistent with the kinetic equation by exploring a splitting based approach. We split the kinetic equation in sources and sinks on the one hand, and transport combined with charge-exchange on the other hand. Combining transport with charge-exchange collisions allows for deriving Hilbert expansion based fluid models. The retrieved fluid models depend on the assumed importance (scaling) of the different terms in the split equation describing transport and charge-exchange. We explore two scalings: the hydrodynamic scaling and the diffusive scaling. The performance of the fluid models with respect to a discrete velocity model and a Monte Carlo reference solver is assessed in numerical experiments. The code used to perform the numerical experiments is openly available.

description: Recent anisotropy studies of UHECR data at energies $\gtrsim$ 40 EeV, have disclosed a correlation of their angular distribution with the extragalactic local structure, specifically with either local starburst galaxies or AGN. Using Monte Carlo simulations taking into account photo-disintegration processes, we further explore a framework in which these UHECRs were accelerated by Centaurus A in a recent powerful outburst before being scattered by magnetic fields associated with local, Council of Giant, extragalactic structure. We find that the observed intermediate scale anisotropies can be accounted for by the Council of Giant structure imposing a response function on the initial outburst of UHECRs from a single source located at Centaurus A's position. The presence of these local structures creates `echoes' of UHECRs after the initial impulse, and focusing effects. The strongest echo wave has a lag of $\sim$ 20 Myr, comparable to the age of synchrotron-emitting electrons in the giant Centaurus A lobes. Through consideration of the composition of both the direct and echo wave components, we find that the distribution of the light (1$<\ln A<$1.5) component across the sky offers exciting prospects for testing the echo model using future facilities such as Auger prime. Our results demonstrate the potential that UHECR nuclei offer, as "composition clocks", for probing propagation scenarios from local sources.

description: The complex metal oxides Mn2ASbO6 (A=In, Sc) with a corundum-related structure A3BO6 have been prepared as polycrystalline powders by a solid state reaction route. The crystal structure and magnetic properties have been investigated using a combination of X-ray and neutron powder diffraction, electron microscopy, calorimetric and magnetic measurements. At room temperature these compounds adopt a trigonal structure, space group R-3 with a = 8.9313(1) Å, c = 10.7071(2) Å (for In) and a = 8.8836(1) Å, c = 10.6168(2) Å (for Sc) which persists down to 1.6 K. The Mn and A cations were found to be randomly distributed over the A-sites. The overall behavior of the magnetization of Mn2InSbO6 and Mn2ScSbO6 is quite similar. In spite of the relatively large amount of Mn ions on the A-site, only short-ranged magnetism is observed. Neutron diffraction patterns of Mn2InSbO6 showed no evidence of a long-range magnetic ordering at 1.6 K, instead only a weak diffuse magnetic peak was observed at low temperatures. The factors governing the observed structural and magnetic properties of Mn2ASbO6 are discussed and compared with those of other Mn-containing complex metal oxides with a corundum-related structure. The influence of the A-cation sublattice on magnetic properties is also considered.

description: Aerodynamic collision avoidance manoeuvres provide an opportunity for satellites in Low Earth Orbits to reduce the risk during close encounters. With rising numbers of satellites and objects in orbit, satellites experience close encounters more frequently. Especially those satellites without thrusting capabilities face the problem of not being able to performimpulsive evasive manoeuvres. For satellites in Low Earth Orbits, though, perturbing forces due to aerodynamic drag may be used to influence their trajectories, thus offering a possibility to avoid collisions. This work introduces a tool for the analysis of aerodynamic collision avoidance manoeuvres. Current space-weather data are employed to estimate the density the satellite encounters. Achievable in-track separation distances following a variation of the ballistic coefficient through a change in attitude are then derived by evaluating an analytical equation from literature. Considering additional constraints for the attitude, e.g., charging phases, and uncertainties in the used parameters, the influence of a manoeuvre on the conjunction geometry and the collision probability is examined. The university satellite Flying Laptop of the University of Stuttgart is used as an exemplary satellite for analysis, which show the general effectiveness of evasive manoeuvres employing aerodynamic drag. First manoeuvring strategies can be deducted and the influence of parameter uncertainties is assessed.

Collective Flow Measurements from the PHENIX Experiment

Subjects: subject: Nuclear Experiment (nucl-ex)

description: Recent collective flow measurements including higher moment event anisotropy from the PHENIX experiment are presented, and the particle type, beam energy dependence and the relation with jet modification are discussed. The measured higher order event anisotropy with event plane defined at forward rapidities and the long range correlation with large $η$ gaps are both consistent with initial geometrical fluctuation of the participating nuclei. In 200 GeV Au+Au collisions, higher order event anisotropy, especially simultaneous description of v$_2$ and v$_3$, is found to give an additional constraining power on initial geometrical condition and viscosity in the hydrodynamic calculations. v$_2$, v$_3$ and v$_4$ are almost unchanged down to the lower colliding energy at 39 GeV in Au+Au. The measured two particle correlation with subtraction of the measured v$_n$ parameters shows a significant effect on the shape and yield in the associate particle $Δϕ$ distribution with respect to the azimuthal direction of trigger particles. However some medium responses from jet suppression or jet modification seems to be observed. Direct photon v$_2$ has been measured in 200 GeV Au+Au collisions. The measured v$_2$ is found to be small at high p$_{\rm T}$ as expected from non-suppressed direct photon R$_{\rm AA}$ $\simeq$ 1, which can be understood as being dominated by prompt photons from initial hard scattering. On the other hand, at lower p$_{\rm T}$ $

description: The Solar Mean Magnetic Field (SMMF) is the mean value of the line of sight (LOS) component of the solar vector magnetic field averaged over the visible hemisphere of the Sun. So far, the studies on SMMF have mostly been confined to the magnetic field measurements at the photosphere. In this study, we calculate and analyse the SMMF using magnetic field measurements at the chromosphere, in conjunction with that of photospheric measurements. For this purpose, we have used full disk LOS magnetograms derived from spectropolarimetric observations carried out in Fe I 630.15 nm and Ca II 854.2 nm by the Synoptic Optical Long term Investigations of the Sun (SOLIS)/Vector Spectromagnetograph (VSM) instrument during 2010 to 2017. It is found from this study that the SMMF at the chromosphere is weaker by a factor of 0.60 compared to the SMMF at the upper photosphere. The correlation analysis between them gives a Pearson correlation coefficient of 0.80. The similarity and reduced intensity of the chromospheric SMMF with respect to the photospheric SMMF corroborate the idea that it is the source of the Interplanetary Magnetic Field (IMF).

description: We present a novel distributed Brillouin optical time domain reflectometer (BOTDR) using standard telecommunication fibers based on single-photon avalanche diodes (SPADs) in gated mode, hd-BOTDR, with a range of 120 km and 10 m spatial resolution. We experimentally demonstrate the ability to perform a distributed temperature measurement, by detecting a hot spot at 100 km. Instead of using a frequency scan like conventional BOTDR, we use a frequency discriminator based on the slope of a fiber Bragg grating (FBG) to convert the count rate of the SPAD into a frequency shift. A procedure to take into account the FBG drift during the acquisition and perform sensitive and reliable distributed measurements is described. We also present the possibility to differentiate strain and temperature.

Spanish heritage language learners in Canadian high school Spanish classes : negotiating ethnolinguistic identities and ideologies
Creators: name: Abdi, Klara
Publisher: name: University of British Columbia
Year: 2009

description: Many young people today are growing up with two or more languages. The development of their heritage language (HL) plays a role in the learners’ intellectual development, cultural identification, and family and HL community relations. Growing numbers of students are thus choosing to enrol in high school or post-secondary language classes for their HL development, posing challenges for teachers who generally have to teach them alongside other (non-HL) “foreign language” (FL) students. Although this area of research, particularly in relation to the teaching of Spanish in the United States, is growing, few studies have looked at the interactions of HL and FL students in mixed classes at the high school level in Canada or elsewhere. This ethnographic case study investigated the interactions and positionings of Spanish HL (SHL) students in intermediate high school Spanish FL (SFL) classes. Three classes were observed over a six-month period and interviews were conducted with all participating students and teachers. One class was then chosen for in-depth analysis for this thesis. The goal of the study was to analyse the nature of the interactions of SHL and SFL students in order to provide insights into how best to accommodate various types of students in one language course. The study found that the SHL students were positioned in various ways depending on the instructional (whole class or group) setting and the nature of the students’ relationships to those they were working with. Their various types and levels of language expertise was one factor in how they were perceived, with greater oral expertise at times making their cultural heritage more salient to their teacher and classmates. The SHL students’ ages and social group affiliations were also important factors affecting their status in class. In fact, their ages or particular groups of friends were sometimes found to be greater factors in how their classmates and teacher perceived them than their language expertise. The study offers new insights into the complex nature of teaching SHL and SFL students in one class at the high school level and offers implications for pedagogy, theory and future research.

description: The kinetic Sunyaev-Zeldovich (kSZ) effect has now become a clear target for ongoing and future studies of the cosmic microwave background (CMB) and cosmology. Aside from the bulk cluster motion, internal motions also lead to a kSZ signal. In this work, we study the rotational kSZ effect caused by coherent large-scale motions of the cluster medium using cluster hydrodynamic cosmological simulations. To utilise the rotational kSZ as a cosmological probe, simulations offer some of the most comprehensive data sets that can inform the modelling of this signal. In this work, we use the MACSIS data set to investigate the rotational kSZ effect in massive clusters specifically. Based on these models, we test stacking approaches and estimate the amplitude of the combined signal with varying mass, dynamical state, redshift and map-alignment geometry. We find that the dark matter, galaxy and gas spins are generally misaligned, an effect that can cause a sub-optimal estimation of the rotational kSZ effect when based on galaxy motions. Furthermore, we provide halo-spin-mass scaling relations that can be used to build a statistical model of the rotational kSZ. The rotational kSZ contribution, which is largest in massive unrelaxed clusters ($\gtrsim$100 $μ$K), could be relevant to studies of higher-order CMB temperature signals, such as the moving lens effect. The limited mass range of the MACSIS sample strongly motivates an extended investigation of the rotational kSZ effect in large-volume simulations to refine the modelling, particularly towards lower mass and higher redshift, and provide forecasts for upcoming cosmological CMB experiments (e.g. Simons Observatory, SKA-2) and X-ray observations (e.g. Athena/X-IFU).

description: We explore the connection between the gravitational wave (GW) merger rates of stellar-mass binary black holes (BBH) and galaxy properties. We do this by generating populations of stars using the binary population synthesis code COMPAS and evolving them in galaxies from the semi-analytic galaxy formation model Shark, to determine the number of mergers occurring in each simulation time-step. We find that metal-rich and massive galaxies with star formation rate (SFR) greater than $1M_{\odot}/ \rm yr$ are 10 times more likely to have GW events compared to younger, less massive and metal poor galaxies. Our simulation with the default input parameters predicts a higher local merger rate density compared to the third GW transient catalogue (GWTC-3) prediction from LIGO, VIRGO and KAGRA, due to short coalescence times, low metallicities and a high SFR at low redshift in the simulation, which produces more BBHs that merge within the age of the Universe compared to observations. We identify alternate remnant mass models that more accurately reproduce the volumetric rate and provide updated fits to the merger rate as a function of redshift. We then investigate the relative fraction of GW events in our simulation that are in observable host galaxies from upcoming galaxy surveys, determining which of those are ideal for tracing host galaxies with high merger rates. The implications of this work can be utilised for constraining stellar evolution models, better informing follow-up programs, and placing informative priors on host galaxies when measuring cosmological parameters such as the Hubble constant.

description: The magnetic behavior of single-crystalline CeCuGa3 has been investigated. The compound forms in a tetragonal BaAl4-type structure consisting of rare-earth planes separated by Cu-Ga layers. If the Cu-Ga site disorder is reduced, CeCuGa3 adopts the related, likewise tetragonal BaNiSn3-type structure, in which the Ce ion are surrounded by different Cu and Ga layers and the inversion symmetry is lost. In the literature conflicting reports about the magnetic order of CeCuGa3 have been published. Single crystals with the centrosymmetric structure variant exhibit ferromagnetic order below approx. 4 K with a strong planar anisotropy. The magnetic behavior above the transition temperature can be well understood by the crystal-field splitting of the 4f Hund's rule ground-state multiplet of the Ce ions.

description: We present a general theory of non-Markovian dynamics for open quantum systems. We explore the non-Markovian dynamics by connecting the exact master equations with the non-equilibirum Green functions. Environmental back-actions are fully taken into account. The non-Markovian dynamics consists of non-exponential decays and dissipationless oscillations. Non-exponential decays are induced by the discontinuity in the imaginary part of the self-energy corrections. Dissipationless oscillations arise from band gaps or the finite band structure of spectral densities. The exact analytic solutions for various non-Markovian environments show that the non-Markovian dynamics can be largely understood from the environmental-modified spectra of the open systems.

On the Evolution of the Cores of Radio Sources and Their Extended Radio Emission

description: The work in this paper aims at determining the evolution and possible co-evolution of radio-loud active galactic nuclei (AGNs) and their cores via their radio luminosity functions (i.e., total and core RLF respectively). Using a large combined sample of 1063 radio-loud AGNs selected at low radio frequency, we investigate the radio luminosity function (RLF) at 408 MHz of steep-spectrum radio sources. Our results support a luminosity-dependent evolution. Using core flux density data of the complete sample 3CRR, we investigate the core RLF at 5.0 GHz. Based on the combined sample with incomplete core flux data, we also estimate the core RLF using a modified factor of completeness. Both results are consistent and show that the comoving number density of radio cores displays a persistent decline with redshift, implying a negative density evolution. We find that the core RLF is obviously different from the total RLF at 408 MHz band which is mainly contributed by extended lobes, implying that the cores and extended lobes could not be co-evolving at radio emission.

Evading the Landau pole in the minimal 3-3-1 model with leptoquarks

description: In its original version, the minimal 3-3-1 model possess a Landau-pole around 2-6 TeV scale. Current LHC bound on $Z^{\prime}$ implies that the $SU(3)_L\times U(1)_X$ symmetry must break spontaneously around 4 TeV which means that the model may lose its perturbative character even before symmetry breaking. This is a disaster for the model. Few attention has been devoted to this problem. Here we investigate the efficiency of scalar leptoquarks in evading or shifting the Landau pole to a harmless energy scale.

Generalized modeling of metal cutting mechanics
Creators: name: Kaymakci, Mustafa
Publisher: name: University of British Columbia
Year: 2009

description: Metal cutting is the most commonly used manufacturing process for producing parts with final dimensions. The aim of engineering science is to model the physics of the process which allows the simulation of part machining operations ahead of costly trials. There is a need to develop generalized models of cutting process which is applicable to various tool geometries and cutting processes in order to simulate machining of industrial parts in virtual environment. This thesis presents a generalized mathematical model which can be used to predict turning, drilling, boring and milling processes. The tool geometry is adopted from ISO 13399 standards. The rake face of the tool is mathematically modeled from ISO13399 model by considering tool geometry, engagement with the workpiece, feed and speed directions of cutting motion. Various geometric features of the tool, such as chamfer, nose radius, and cutting edge angles, are considered in developing coordinate transformation models between the machine motion and tool coordinate systems. The cutting forces on the rake face are defined in the direction of chip flow and per-pendicular to the rake face. The cutting force coefficients in the two directions are either identified mechanistically by conducting experiments specific to the tool geometry, or using orthogonal to oblique transformation of shear angle, average friction angle and shear stress. The friction and normal forces on the rake face are transformed to both stationary and rotating tool coordinate systems defined on the machine tool.
Thermal Stability of C4+4nH8 Polycubanes

description: The temperature dependences of the lifetimes of polycubanes C4+4nH8 with n = 2 - 5 up to their decomposition have been directly calculated using the molecular dynamics method. It has been shown that the activation energy of decomposition of these metastable clusters, in which the C-C bonds form an angle of 90^0 that is not characteristic of carbon systems, rapidly decreases with an increase in n due to the lowering of the energy barrier that prevents the decomposition of the clusters. This has cast some doubt on the recently made suggestion that there exist nanotubes (n >> 1) with a square cross section. Nonetheless, the stability of bicubane (n = 2) and tricubane (n = 3) has proved to be sufficient for their existence at the liquid-nitrogen temperature.

description: Enterocytozoon hepatopenaei (EHP) is a parasite that mostly affects shrimp; it is linked to spore-forming and obligatory intracellular microsporidia and causes growth retardation and body length fluctuation, which results in financial consequences for the shrimp industry in Asian nations. However, the introduction of technologies to detect EHP has been complicated by the absence of a thorough knowledge of the properties of spore wall proteins (SWPs) linked to host infection. Thus, characterization, feature identification, 3D modeling of protein sequence, prediction of transmembrane regions, motif analysis, as well as model validation of SWPs can help improve drug delivery in the future. Conservation analysis was performed using ClustalW. InterPro, MEMEsuite, and TMHMM Server v2.0 were used to perform motif analysis, family domain prognosis, and transmembrane region analysis, respectively. Finally, the Alphafold2 server was used for analogy modeling and 3D layout. Different model validation servers were used to validate the protein structural model. Physicochemical features for SWPs were analyzed and found molecular weight around 16.701 KDa-38.314 KDa, theoretical pI 5.25–9.05, instability index 32.04–48.89, aliphatic index 76.49–99.84, grand average of hydropathicity (GRAVY) – 0.059 to −0.892. Each SWP was discovered to be hydrophilic. There was no significant region detected in the conserved region analysis. Both a lower and higher E value were found by the motif analysis. For most of the proteins, there were no transmembrane regions. Finally, analogous 3D models for each protein were created and verified using various bioinformatics tools and software. This investigation could aid in the further research of diseases and the development of drug delivery systems.

Orbit Representations from Linear mod 1 Transformations

description: We show that every point $x_0\in [0,1]$ carries a representation of a $C^*$-algebra that encodes the orbit structure of the linear mod 1 interval map $f_{β,α}(x)=βx +α$. Such $C^*$-algebra is generated by partial isometries arising from the subintervals of monotonicity of the underlying map $f_{β,α}$. Then we prove that such representation is irreducible. Moreover two such of representations are unitarily equivalent if and only if the points belong to the same generalized orbit, for every $α\in [0,1[$ and $β\geq 1$.

description: We establish that the interplay of itinerant fermions with localized magnetic moments on a checkerboard lattice leads to magnetic flux-phases. For weak itineracy the flux-phase is coplanar and the electronic dispersion takes the shape of graphene-like Dirac fermions. Stronger itineracy drives the formation of a non-coplanar, chiral flux-phase, in which the Dirac fermions acquire a topological mass that is proportional to a ferromagnetic spin polarization. Consequently the system self-organizes into a ferromagnetic Quantum Anomalous Hall state in which the direction of its dissipationless edge-currents can be switched by an applied magnetic field.

Electrons surf phason waves in moiré bilayers

description: We investigate the effect of thermal fluctuations on the atomic and electronic structure of a twisted MoSe$_{2}$/WSe$_{2}$ heterobilayer using a combination of classical molecular dynamics and \textit{ab-initio} density functional theory calculations. Our calculations reveal that thermally excited phason modes give rise to an almost rigid motion of the moiré lattice. Electrons and holes in low-energy states are localized in specific stacking regions of the moiré unit cell and follow the thermal motion of these regions. In other words, charge carriers surf phason waves that are excited at finite temperatures. Small displacements at the atomic scale are amplified at the moiré scale, which gives rise to significant surfing speeds. We also show that such surfing survives in the presence of a substrate and disorder. This effect has potential implications for the design of charge and exciton transport devices based on moiré materials.
