A transpacific aesthetic of redress : narrating disability and debilitation in Em, Burning vision, and Dogs at the perimeter
Creators: name: Lim, Olivia
Publisher: name: University of British Columbia
Year: 2024

description: This thesis attends to questions of redress and justice that arise from the ways American militarism in the transpacific endures in the body-mind as disability and debility. Focusing on the Cold War in Asia, including the atomic bombing of Hiroshima and Nagasaki, the legacy of the War in Vietnam, and the rise of the Khmer Rouge regime following the U.S. bombing of Cambodia, my research intervenes in liberal humanist juridical redress culture’s pathologization of disability as an index of harm and expresses its critical limits in accounting for the long temporality and nebulous scope of debilitative violence. Mobilizing the theoretical apparatuses of critical disability studies, redress studies, critical refugee studies, and scholarship on the Cold War in Asia, I theorize a transpacific aesthetic of redress, a cripistemology of redress that develops from aesthetic forms that work to produce alternative fields of sensibility surrounding disability and debilitative violence, making perceivable the complex transpacific entanglements of survival, beauty, and harm in the afterlives of U.S. imperialism. To articulate this epistemology of redress, I close read contemporary transnational literature that engages with histories of U.S. militarism in the transpacific. I consider how the formal qualities of these texts, particularly fragmentation and non-linear narrative, orient us towards frameworks of redress that emerge from recognizing U.S. imperialism’s debilitative violence as a condition of possibility for disability, while still resisting the reduction of disability to a redressable harm. Chapter One examines the quantification of violence in Kim Thúy’s novel Em, exploring critical ambivalences that express the entanglement of beauty and debilitation within the conflict’s chemical legacy. Chapter Two reads Marie Clements’s play Burning Vision for the slow violences of uranium that highlight the temporal limits of contemporary redress frameworks, turning to debilitation to theorize modes of contending with this unredressability. Chapter Three analyzes the rhythms of debilitative time held within Madeleine Thien’s novel Dogs at the Perimeter to conceptualize a theory of fugitive redress that unsettles state-based justice paradigms. Ultimately, I argue that a transpacific aesthetic of redress enables more capacious understandings of interconnection, disability, and debilitation that offers a radical reimagining of redress culture.

description: We have investigated the upper critical field anisotropy and magnetotransport properties of Fe1.14(1)Te0.91(2)S0.09(2) single crystals in stable magnetic fields up to 35 T. The results show that u0Hc2(T) along the c axis and in the ab-plane exhibit saturation at low temperatures. The anisotropy of u0Hc2(T) decreases with decreasing temperature, becoming nearly isotropic for T->0. Our analysis indicates that the spin-paramagnetic pair-breaking with spin-orbital scattering is responsible for the behavior of u0Hc2(T). Furthermore, from analysis of the normal state properties, we show evidence that the excess Fe acting as Kondo-type impurities is a key factor determining the normal and superconducting state physical properties.

On the interaction of pebble accreting embryos with the gaseous disc: importance of thermal forces

description: A planetary embryo embedded in a gaseous disc can grow by pebble accretion while subjected to a gravitational force from the disc that changes its orbital elements. Usually, that force is considered to arise from the Lindblad and corotation resonances with the embryo. However, more important contributions exist for low-mass planets. Radiative thermal diffusion in the vicinity of embryos yields an additional contribution to the disc's force that damps the eccentricity and inclination much more vigorously than the resonant interaction with the disc, and that in general induces fast inward migration. In addition, the irradiation of the disc by a hot embryo gives rise to an additional contribution that excites eccentricity and inclination, and induces outward migration. Which of the two contributions dominates depends on the embryo's luminosity. We assess the importance of these contributions (termed thermal forces) on the dynamics and growth of a set of pebble-accreting embryos initially of Martian mass, by means of N-body simulations that include analytic expressions for the disc's force. We find very different outcomes for the embryos subjected to thermal forces and those subjected only to resonant forces. Importantly, we find that the median final mass of the embryos subjected to thermal forces is nearly independent of the metallicity, whereas this mass roughly scales with the metallicity when they are subjected only to resonant forces. These results can be explained by the strong damping of eccentricity and inclination at low metallicity, which enhances the embryos' accretion efficiency.

description: Previous work [Gong and Brumer, Phys. Rev. Lett., 97, 240602 (2006)] motivates this study as to how asymmetry-driven quantum ratchet effects can persist despite a corresponding fully chaotic classical phase space. A simple perspective of ratchet dynamics, based on the Heisenberg picture, is introduced. We show that ratchet effects are in principle of common origin in classical and quantum mechanics, though full chaos suppresses these effects in the former but not necessarily the latter. The relationship between ratchet effects and coherent dynamical control is noted.

Intergenerational conflict and diasporic identity : a study of memory and affect in Jhumpa Lahiri's The namesake and The lowland
Creators: name: Huda, Dravida
Publisher: name: University of British Columbia
Year: 2024

description: The study of memory and affect has gained importance in the critical examination of intergenerationality since the advent of memory theory relating to the Holocaust. While in recent times, scholarly attention tends to view memory and affect in their fluid as well as multidirectional capacities, the two interconnected concepts also offer substantial insight in contexts where the acts and repercussions of memory and affect’s transmission from one generation to the next are conditioned by specific circumstances such as that of diaspora. Diaspora studies offer a broad spectrum of situations related to migratory movement, such as generational conflict, cultural assimilation, hybrid identity, multiculturalism, and transnationalism. These concepts are consistently raised in the extant criticism of prominent Indo-American author, Jhumpa Lahiri, and her nuanced rendition of the Bengali diaspora in the US. However, research on Lahiri’s fiction focuses on postcolonialism while generally overlooking the issues of memory and affect, and their capacity to provide new and important perspectives on intergenerational conflict and diasporic identity. My MA thesis addresses this significant gap in Lahiri studies and investigates two of the author’s novels, The Namesake and The Lowland. My study proposes that the migratory quality of memory and the affect associated with it instigate intergenerational conflicts in a diasporic situation, and eventually impact the formation of second generation diasporic identity specifically. I consider purposefully withheld memories of migration by first generation members of diaspora, the resultant “absent-presence” of affect in the second generation of diaspora, and finally the repercussions of such affect as it materializes in different forms of struggle for the second generation. Ultimately, my work contributes to an understanding of Lahiri’s representations of the fluidity of diasporic identity, as it is strongly connected to the movement of memory and affect between generations.

description: Neutral hydrogen is ubiquitous, absorbing and emitting 21 cm radiation throughout much of the Universe's history. Active sources of perturbations, such as cosmic strings, would generate simultaneous perturbations in the distribution of neutral hydrogen and in the Cosmic Microwave Background (CMB) radiation from recombination. Moving strings would create wakes leading to 21 cm brightness fluctuations, while also perturbing CMB light via the Gott-Kaiser-Stebbins effect. This would lead to spatial correlations between the 21 cm and CMB anisotropies. Passive sources, like inflationary perturbations, predict no cross correlations prior to the onset of reionization. Thus, observation of any cross correlation between CMB and 21 cm radiation from dark ages would constitute evidence for new physics. We calculate the cosmic string induced correlations between CMB and 21 cm and evaluate their observability.

description: Several NP-hard problems are solved exactly using exponential-time branching strategies, whether it be branch-and-bound algorithms, or bounded search trees in fixed-parameter algorithms. The number of tractable instances that can be handled by sequential algorithms is usually small, whereas massive parallelization has been shown to significantly increase the space of instances that can be solved exactly. However, previous centralized approaches require too much communication to be efficient, whereas decentralized approaches are more efficient but have difficulty keeping track of the global state of the exploration. In this work, we propose to revisit the centralized paradigm while avoiding previous bottlenecks. In our strategy, the center has lightweight responsibilities, requires only a few bits for every communication, but is still able to keep track of the progress of every worker. In particular, the center never holds any task but is able to guarantee that a process with no work always receives the highest priority task globally. Our strategy was implemented in a generic C++ library called GemPBA, which allows a programmer to convert a sequential branching algorithm into a parallel version by changing only a few lines of code. An experimental case study on the vertex cover problem demonstrates that some of the toughest instances from the DIMACS challenge graphs that would take months to solve sequentially can be handled within two hours with our approach.

description: Automatic singing evaluation independent of reference melody is a challenging task due to its subjective and multi-dimensional nature. As an essential attribute of singing voices, vocal timbre has a non-negligible effect and influence on human perception of singing quality. However, no research has been done to include timbre information explicitly in singing evaluation models. In this paper, a data-driven model TG-Critic is proposed to introduce timbre embeddings as one of the model inputs to guide the evaluation of singing quality. The trunk structure of TG-Critic is designed as a multi-scale network to summarize the contextual information from constant-Q transform features in a high-resolution way. Furthermore, an automatic annotation method is designed to construct a large three-class singing evaluation dataset with low human-effort. The experimental results show that the proposed model outperforms the existing state-of-the-art models in most cases.

description: In recent years, twisted bilayer graphene has become a hot topic and inspired the research upsurge of photonic moiré lattice. Here, we designed a photonic moiré superlattice with two synthetic twist angles and constructed a synthetic moiré sphere based on these two angles. Thus, we have more degrees of freedom to design the band structure flexibly. A type of transition photonic bands (TPBs) is obtained in such a moiré superlattice. We investigate the influence of two twist angles on TPBs and find a series of magic angle pairs with optimal band compression of TPB. The interesting optical properties of TPBs are experimentally demonstrated, including pulse delay, nonlinear optical enhancement, and pulse width compression. Our work introduces a new path to explore multi-twist angles moiré superlattices and reveals that the designed photonic moiré superlattice based on moiré spheres has broad application prospects including optical signal processing, nonlinear optics processes ,and other light-matter interactions.

We measure the magnitude, phase, and fit fraction of K*(892) K+, phi(1020)pi+, K0*(1430)K+, f_0(980)pi+, f_0(1710)pi+, and f_0(1370)pi+ contributions and limit the possible contributions of other KK and Kpi resonances that could appear in this decay.

description: We measure the frequency spectra of random spin fluctuations, or "spin noise", in ensembles of (In,Ga)As/GaAs quantum dots (QDs) at low temperatures. We employ a spin noise spectrometer based on a sensitive optical Faraday rotation magnetometer that is coupled to a digitizer and field-programmable gate array, to measure and average noise spectra from 0-1 GHz continuously in real time with sub-nanoradian/root-Hz sensitivity. Both electron and hole spin fluctuations generate distinct noise peaks, whose shift and broadening with magnetic field directly reveal their g-factors and dephasing rates within the ensemble. A large, energy-dependent anisotropy of the in-plane hole g-factor is clearly exposed, reflecting systematic variations in the average QD confinement potential.

This moduli space is a quasi-projective scheme. This is accomplished by showing that such framed sheaves may be considered as stable pairs in the sense of Huybrechts and Lehn. We characterize the obstruction to the smoothness of the moduli space, and discuss some examples on rational surfaces.

description: Bound states in the continuum (BICs) have attracted significant interest in recent years due to their unique optical properties, such as infinite quality factor and wave localization. In order to improve the optical performance of BICs based devices, more degrees of freedom are required to tune BICs in high-dimension parameter space for practical applications. To effectively tune more BICs, we form a 2D synthetic parameter space based on a nanohole metasurface array. Multiple symmetry protected BIC modes with high Q factors can be achieved at high-order symmetry point. Through manipulating asymmetry parameters, BIC lines formed by a series of BIC modes can be found in the 2D synthetic parameter space. Moreover, the electric field distributions are investigated to demonstrate the generation and evolution of BICs. By measuring the absorption spectra, the tuning of multiple BICs with synthet-ic asymmetry parameters is experimentally explored, which agrees well with theoretical results. Therefore, our de-sign can provide new insight for a variety of on-chip applications, such as non-linear devices, integrated nanolasing array and high-resolution sensors for infrared molecular detection.

description: We propose that thermal noise in local stripe orientation should be readily detectable via STM on systems in which local stripe orientations are strongly affected by quenched disorder. Stripes, a unidirectional, nanoscale modulation of electronic charge, are strongly affected by quenched disorder in two-dimensional and quasi-two-dimensional systems. While stripe orientations tend to lock to major lattice directions, dopant disorder locally breaks rotational symmetry. In a host crystal with otherwise $C_4$ rotational symmetry, stripe orientations in the presence of quenched disorder map to the random field Ising model. While the low temperature state of such a system is generally a stripe glass in two dimensional or strongly layered systems, as the temperature is raised, stripe orientational fluctuations become more prevalent. We propose that these thermally excited fluctuations should be readily detectable in scanning tunneling spectroscopy as {\em telegraph noise} in the high voltage part of the local $I(V)$ curves. We predict the spatial, temporal, and thermal evolution of such noise, including the circumstances under which such noise is most likely to be observed. In addition, we propose an in-situ test, amenable to any local scanning probe, for assessing whether such noise is due to correlated fluctuations rather than independent switchers.

title: Das Paradigma des Brudermordes in der Darstellung römischer Bürgerkriege
Creators: name: Lampl, Tamara
Year: 2023

description: Roms Bürgerkriege werden von lateinischen Autoren als Akt der Selbstzerstörung und als fester Bestandteil der römischen Geschichte wahrgenommen. Szenen, bei denen enge Familienmitglieder – insbesondere Brüder – aus politischen Interessen gegeneinander kämpfen, stellen die vielleicht prägnanteste Repräsentation von Bürgerkriegen dar. Ziel dieser Arbeit war die Bestimmung des Phänomens Bruderkampf bei lateinischen Autoren hinsichtlich seiner Funktionen in der lateinischen Literatur. Unterschieden wurde dabei zwischen dem bewussten Töten des eigenen Bruders, das durch Streitigkeiten bezüglich der Thronfolge motiviert ist, und dem unbeabsichtigten Morden auf dem Schlachtfeld. Für Ersteres wurden zwei Beispiele aus der Mythologie näher beleuchtet: einerseits Romulus‘ Mord an Remus, andererseits das thebanische Brüderpaar Eteocles und Polynices. Für Zweiteres, die unbewusste Tötung des eigenen Bruders, wurde die Rezeption einer Szene des Historiographen Sisenna analysiert, bei der ein Soldat auf dem Schlachtfeld erkennt, dass es sich bei dem getöteten Gegner um seinen eigenen Bruder handelt, und anschließend Suizid begeht. Es zeigte sich, dass die Darstellungsweise in vielerlei Hinsicht von den beiden Mythen beeinflusst ist. Weiters wurde ein unterschiedlicher Einsatz der Episode je nach Argumentationsziel sichtbar: Während sie in der Historiographie (etwa bei Livius) zur Illustration von Bürgerkriegsperioden genutzt wird, dient der Selbstmord des Soldaten bei Tacitus zur Vorhebung römischer Idealwerte. Bei christlichen Autoren fungiert sie hingegen als Negativbespiel für pagane Ideologien. Dabei konnte herausgearbeitet werden, dass Orosius die Definition der Episode als bewussten oder unbewussten Brudermord als hinfällig betrachtet, da die Bereitschaft zum Töten von Blutsverwandten überhaupt erst Bürgerkriege ermögliche.

description: Blind image quality assessment is a challenging task particularly due to the unavailability of reference information. Training a deep neural network requires a large amount of training data which is not readily available for image quality. Transfer learning is usually opted to overcome this limitation and different deep architectures are used for this purpose as they learn features differently. After extensive experiments, we have designed a deep architecture containing two CNN architectures as its sub-units. Moreover, a self-collected image database BIQ2021 is proposed with 12,000 images having natural distortions. The self-collected database is subjectively scored and is used for model training and validation. It is demonstrated that synthetic distortion databases cannot provide generalization beyond the distortion types used in the database and they are not ideal candidates for general-purpose image quality assessment. Moreover, a large-scale database of 18.75 million images with synthetic distortions is used to pretrain the model and then retrain it on benchmark databases for evaluation. Experiments are conducted on six benchmark databases three of which are synthetic distortion databases (LIVE, CSIQ and TID2013) and three are natural distortion databases (LIVE Challenge Database, CID2013 and KonIQ-10 k). The proposed approach has provided a Pearson correlation coefficient of 0.8992, 0.8472 and 0.9452 subsequently and Spearman correlation coefficient of 0.8863, 0.8408 and 0.9421. Moreover, the performance is demonstrated using perceptually weighted rank correlation to indicate the perceptual superiority of the proposed approach. Multiple experiments are conducted to validate the generalization performance of the proposed model by training on different subsets of the databases and validating on the test subset of BIQ2021 database.
Status and development needs of urban forest inventories in British Columbia, Canada
Creators: name: Miao, Alice
Publisher: name: University of British Columbia

description: Many Canadian cities have begun developing urban forestry strategies that provide strategic guidance for the preservation and revitalization of their urban tree populations and urban green spaces. However, while tree inventory programs are often identified as the cornerstone of such strategies, a standardized practical framework for tree inventory practices, specifically designed for urban forests, has been slow to emerge. This research: 1) examines how urban forest inventories are understood by British Columbia (BC) municipalities; 2) evaluates the status of, and identifies trends in, BC municipal urban forest inventory programs for the first time, and 3) identifies inventory elements and provides recommendations for a more standardized and enhanced municipal urban forest inventory program in BC. A total of 162 BC municipalities were invited to share information on their municipal urban forest inventory programs via an online questionnaire. The questionnaire response rate was 50%. Key findings included the discovery that urban forests and urban forest inventory programs were not well understood and managed in a consistent manner across BC municipalities, and that this trend is likely to continue in the absence of a concerted effort to reverse it. Increased municipal expenditures on parks, culture and recreation was positively correlated to the existence of an urban forest inventory system, among other contributing factors such as the presence of an urban forest strategy, the location of the municipality and municipal policies. Street trees were identified as the most common focus of BC municipal inventory activities, and inventory data were commonly used for both strategic planning and daily operations. Based on these findings, I proposed a list of recommendations for the development of an approach to urban forest inventory programs for BC municipalities that is sensitive to local circumstances.

description: We present an extended study of single impurity atoms at the interface between the half-metallic ferromagnetic zinc-blende CrAs compound and the zinc-blende binary InAs and CdSe semiconductors in the form of very thin multilayers. Contrary to the case of impurities in the perfect bulk CrAs studied in [I. Galanakis and S.G. Pouliasis, J. Magn. Magn. Mat. 321 (2009) 1084] defects at the interfaces do not alter in general the half-metallic character of the perfect systems. The only exception are Void impurities at Cr or In(Cd) sites which lead, due to the lower-dimensionality of the interfaces with respect to the bulk CrAs, to a shift of the $p$ bands of the nearest neighboring As(Se) atom to higher energies and thus to the loss of the half-metallicity. But Void impurities are Schottky-type and should exhibit high formation energies and thus we expect the interfaces in the case of thin multilayers to exhibit a robust half-metallic character.

description: A recent experimental demonstration of a parametric magnetization oscillation excited by applying a microwave voltage to a ferromagnetic metal will be applicable not only to a new magnetization switching method but also to bio-inspired computing. It should be, however, noted that a phase of the parametric magnetization oscillation is not uniquely locked, related to the fact that a frequency of the microwave voltage is twice the value of the magnetization oscillation. There are two possible phases in the parametric oscillation state, and which of the two is realized depends on the initial condition of the magnetization. Here, we examine two approaches to lock the phase uniquely. One is to suppress the distribution of the initial state by enhancing the perpendicular magnetic anisotropy before applying microwave voltage, and the other is to use a sweeping frequency. Through numerical simulation of the Landau-Lifshitz-Gilbert equation and quantification of locked rate, we find that the sweeping frequency is more effective to lock the phase of the parametric magnetization oscillation.

description: The International Gamma-Ray Astrophysics Laboratory (INTEGRAL) is discovering hundreds of new hard X-ray sources, many of which remain unidentified. We report on optical spectroscopy of five such sources for which X-ray observations at lower energies (~0.5-10 keV) and higher angular resolutions than INTEGRAL have allowed for unique optical counterparts to be located. We find that IGR J16426+6536 and IGR J22292+6647 are Type 1 Seyfert active galactic nuclei (with IGR J16426+6536 further classified as a Seyfert 1.5) which have redshifts of z=0.323 and z=0.113, respectively. IGR J18308-1232 is identified as a cataclysmic variable (CV), and we confirm a previous identification of IGR J19267+1325 as a magnetic CV. IGR J18214-1318 is identified as an obscured high mass X-ray binary (HMXB), which are systems thought to have a compact object embedded in the stellar wind of a massive star. We combine Chandra fluxes with distances based on the optical observations to calculate X-ray luminosities of the HMXB and CVs, finding L_(0.3-10 keV)=5e36 erg s^-1 for IGR J18214-1318, L_(0.3-10 keV)=1.3e32 erg s^-1 for IGR J18308-1232, and L_(0.3-10 keV)=6.7e32 erg s^-1 for IGR J19267+1325.

description: Input-driven dynamical systems have attracted attention because their dynamics can be used as resources for brain-inspired computing. The recent achievement of human-voice recognition by spintronic oscillator also utilizes an input-driven magnetization dynamics. Here, we investigate an excitation of input-driven chaos in magnetization dynamics by voltage controlled magnetic anisotropy effect. The study focuses on the parametric magnetization oscillation induced by a microwave voltage and investigates the effect of random-pulse input on the oscillation behavior. Solving the Landau-Lifshitz-Gilbert equation, temporal dynamics of the magnetization and its statistical character are evaluated. In a weak perturbation limit, the temporal dynamics of the magnetization are mainly determined by the input signal, which is classified as input-driven synchronization. In a large perturbation limit, on the other hand, chaotic dynamics are observed, where the dynamical response is sensitive to the initial state. The existence of chaos is also identified by the evaluation of the Lyapunov exponent.

description: Diese Masterarbeit beschäftigt sich umfassend mit der Abtrennung Südtirols nach dem Ersten Weltkrieg. Obwohl die Annexion Südtirols bereits über hundert Jahre zurückliegt, bleibt das Thema aufgrund von wiederaufkommenden Konflikten in Bezug auf Minderheiten und Unabhängigkeitsbestrebungen in verschiedenen Regionen aktuell. Um den Hintergrund für die Abtrennung Südtirols zu verdeutlichen, wird im ersten Teil der Arbeit zunächst ein umfassender historischer Rückblick geschaffen. In weiterer Folge beschäftigt sich die Arbeit intensiv mit der Abtrennung Südtirols und mit den direkten Folgen der Annexion. Dabei steht im Fokus, wie mit den deutschsprachigen Südtiroler*innen umgegangen wurde und wie die österreichische Bevölkerung und die Presse auf die Teilung Tirols reagierte. Im zweiten Teil dieser Masterarbeit werden drei historische österreichische Zeitungen aus den Jahren 1918-1920 analysiert. Dabei soll vor allem untersucht werden, wie die österreichischen Autoren über die Abtrennung Südtirols berichtet haben und welche Stimmung und Haltung sie den Leser*innen damit vermitteln. Im dritten und letzten Teil dieser Arbeit wird ein Unterrichtskonzept für den Geschichtsunterricht einer 3. Klasse der Sekundarstufe I entwickelt. Ziel dieses Unterrichtskonzeptes ist es, die Schüler*innen unter anderem auch mithilfe von historischen Zeitungen mit dem Thema ‚Annexion Südtirols‘ vertraut zu machen. Zudem soll für die Schüler*innen auch ein Lebensweltbezug hergestellt werden.

description: We consider the hydrodynamics of relativistic conformal field theories at finite temperature and its slow motions limit, where it reduces to the incompressible Navier-Stokes equations. The symmetries of the equations and their solutions are analyzed. We construct exact solutions with finite time singularities of one-dimensional relativistic conformal hydrodynamic motions, and use them to generate multi-dimensional solutions via special conformal transformations. These solutions, however, are shown to have no non-trivial slow motions limit. A simple non-equilibrium steady state in the form of a shock solution is constructed, and its inner structure is analyzed. We demonstrate that the derivation of the gravitational dual description of conformal hydrodynamics is analogous to the derivation of hydrodynamics equations from the Boltzmann equation. The shock solution is shown to correspond to a domain-wall solution in gravity. We show that the solutions to the non-relativistic incompressible Navier-Stokes equations play a special role in the construction of global solutions to gravity.

description: This paper describes a novel atom-cavity interaction induced by periodically poled atom-cavity coupling constant which leads to multiple narrow photoemission bands for an initially inverted two-level atom under the strong coupling condition. The emission bandpass narrowing has a close analogy with the folded Solc filter in the context of quasi-phase matching by periodic poling. We present a closed form solution of the emission probability at the end of interaction and deduce the multiple phase matching condition for this system which is programmable by the interaction time. The Bloch sphere analysis provides a clear understanding of the underlying atomic dynamics associated with the multiple resonances in the semiclassical limit. Furthermore, we show that this interaction can be applied to generation of the nonclassical field with sub-Poisson photon statistics.

description: We study spin-rotation effects in a magnetic molecule bridged between two conducting leads. Dynamics of the total angular momentum couples spin tunneling to the mechanical rotations. Landau-Zener spin transition produced by the time-dependent magnetic field generates a unique pattern of mechanical oscillations that can be detected by measuring the electronic tunneling current through the molecule.

description: Using standard techniques in string/D-brane scattering amplitude computations, we evaluate the scattering of open strings off D-particles in brane world scenarios. The D-particles are viewed as D3 branes wrapped up around three cycles, and their embedding in brane worlds constitutes a case of intersecting branes, among which strings are stretched, representing various types of excitations of the Standard Model (SM) particles in the low-energy limit. Our analysis, reveals interesting and novel selection rules for the resulting causal time delays, proportional to the energy of the incident matter state, from the processes of splitting, capture and re-emission of the latter by the D-particles. In particular, we show that there are relatively large time delays only for excitations that belong to the Cartan subalgebra of the SM gauge group, which notably includes photons. We discuss the possible relevance of these results to the models of space time foam predicting a non-trivial vacuum refractive index for photons and the associated cosmic γ-ray phenomenology. In particular, we demonstrate how low-string-scale models can be falsified already in this context, by current astrophysical observations of cosmic photons, and how such observations serve as a way to discriminate low- from high-string scale models.

description: We consider the scenario of a fluctuating spacetime due to a deformed commutation relation with a fluctuating deformation parameter, or to a fluctuating metric tensor. By computing the resulting dynamics and averaging over these fluctuations, we find that a system experiences a decoherence in the momentum basis. We studied the predictions of the model for a free particle and an harmonic oscillator. Using experimental data taken from a mechanical oscillator prepared in quantum states of motion, we put a bound on the free parameters of the considered model. In addition, we comment on how these measurements can also provide bounds to other phenomenological quantum gravity models, such as the length scale for nonlocal dynamics.
