Non-minimal gravitational reheating during kination

description: A new mechanism is presented which can reheat the Universe in non-oscillatory models of inflation, where the inflation period is followed by a period dominated by the kinetic density for the inflaton field (kination). The mechanism considers an auxiliary field non-minimally coupled to gravity. The auxiliary field is a spectator during inflation, rendered heavy by the non-minimal coupling to gravity. During kination however, the non-minimal coupling generates a tachyonic mass, which displaces the field, until its bare mass becomes important, leading to coherent oscillations. Then, the field decays into the radiation bath of the hot big bang. The model is generic and predictive, in that the resulting reheating temperature is a function only of the model parameters (masses and couplings) and not of initial conditions. It is shown that reheating can be very efficient also when considering only the Standard Model.

description: Continued gravitational collapse gives rise to curvature singularities. If a curvature singularity is globally naked then the space-time may be causally future ill-behaved admitting closed time-like or null curves which extend to asymptotic distances and generate a Cosmic Time Machine (de Felice (1995) Lecture Notes in Physics 455, 99). The conjecture that Cosmic Time Machines give rise to high energy impulsive events is here considered in more details.

Evolution of a capsule based dry powder aerosol generator for inhalation exposure of rodents in support of early drug development
Creators: name: Paul, Graham
Publisher: name: F1000 Research Limited
Year: 2019

description: The development of new medicines by the pharmaceutical industry is resource intensive due, at least in part, to a high attrition rate of candidate drugs in later stage development. Development programmes for inhaled compounds can consume large masses of candidate drugs, relative to other dose routes, and this is especially true of conventional inhalation exposure systems used for presentation of dry powder aerosols to laboratory animals. Compound requirements thus impose limitations for experiments early in respiratory drug development, when candidate drugs are in short supply.

This presentation will review the development of a capsule based aerosol generator designed to consume relatively small masses of test material for inhalation administration of dry powder aerosols to rodents. Technical challenges and the performance of a prototype will be discussed.
Theory of spin and charge fluctuations in the Hubbard model

description: A self-consistent theory of both spin and charge fluctuations in the Hubbard model is presented. It is in quantitative agreement with Monte Carlo data at least up to intermediate coupling $(U\sim 8t)$. It includes both short-wavelength quantum renormalization effects, and long-wavelength thermal fluctuations which can destroy long-range order in two dimensions. This last effect leads to a small energy scale, as often observed in high temperature superconductors. The theory is conserving, satisfies the Pauli principle and includes three-particle correlations necessary to account for the incipient Mott transition.

description: By coupling a $Λ$-type quantum emitter to a chiral waveguide, in which the polarization of a photon is locked to its propagation direction, we propose a controllable photon-emitter interface for quantum networks. We show that this chiral system enables the SWAP gate and a hybrid-entangling gate between the emitter and a flying single photon. It also allows deterministic storage and retrieval of single-photon states with high fidelities and efficiencies. In short, this chirally coupled emitter-photon interface can be a critical building block toward a large-scale quantum network.

Lossless Compression in HEVC with Integer-to-Integer Transforms
Creators: name: Kamisli, Fatih
Publisher: name: arXiv
Year: 2016
Subjects: subject: Multimedia (cs.MM)
subject: FOS: Computer and information sciences

description: Many approaches have been proposed to support lossless coding within video coding standards that are primarily designed for lossy coding. The simplest approach is to just skip transform and quantization and directly entropy code the prediction residual, which is used in HEVC version 1. However, this simple approach is inefficient for compression. More efficient approaches include processing the residual with DPCM prior to entropy coding. This paper explores an alternative approach based on processing the residual with integer-to-integer (i2i) transforms. I2i transforms map integers to integers, however, unlike the integer transforms used in HEVC for lossy coding, they do not increase the dynamic range at the output and can be used in lossless coding. Experiments with the HEVC reference software show competitive results.

A possible violation of cosmic censorship is avoided because the universe recollapses just when a naked singularity was about to form. The model has been chosen to have $c=4$ (or $\widehat c=4$ in the supersymmetric case), just like four dimensional Minkowski space.

Combining the Ginzburg-Landau theory with the bosonization techniques, we predict that the repulsive interaction between higher-band bosons and the quantum fluctuation can induce the ground state with a finite angular momentum around the trapped axis. In this state, the Z_2 reflection symmetry (clockwise or anticlockwise rotations) is spontaneously broken.

description: Muon ionization cooling involves passing particles through solid or liquid absorbers. Careful simulations are required to design muon cooling channels. New features have been developed for inclusion in the transfer map code COSY Infinity to follow the distribution of charged particles through matter. To study the passage of muons through material, the transfer map approach alone is not sufficient. The interplay of beam optics and atomic processes must be studied by a hybrid transfer map--Monte-Carlo approach in which transfer map methods describe the deterministic behavior of the particles, and Monte-Carlo methods are used to provide corrections accounting for the stochastic nature of scattering and straggling of particles. The advantage of the new approach is that the vast majority of the dynamics are represented by fast application of the high-order transfer map of an entire element and accumulated stochastic effects. The gains in speed are expected to simplify the optimization of cooling channels which is usually computationally demanding. Progress on the development of the required algorithms and their application to modeling muon ionization cooling channels is reported.

description: We present a regularisation approach to the study of the quantum dynamics of the Mixmaster universe which allows to approximate the anisotropy potential with the explicitly integrable periodic 3-particle Toda system. This approach is based on a covariant Weyl-Heisenberg integral quantization. Such a procedure naturally amplifies the dynamical role of the underlying Toda system by smoothing out the three canyons of the anisotropy potential. Since the respective eigenfunctions can be explicitly constructed, our finding paves the way to a novel perturbative approach to the quantum Mixmaster dynamics.

description: The Alpha Magnetic Spectrometer (AMS), whose final version AMS-02 is to be installed on the International Space Station (ISS) for at least 3 years, is a detector designed to measure charged cosmic ray spectra with energies up to the TeV region and with high energy photon detection capability up to a few hundred GeV, using state-of-the-art particle identification techniques. Following the successful flight of the detector prototype (AMS-01) aboard the space shuttle, AMS-02 is expected to provide a significant improvement on the current knowledge of the elemental and isotopic composition of hadronic cosmic rays due to its long exposure time (minimum of 3 years) and large acceptance (0.5 m^2 sr) which will enable it to collect a total statistics of more than 10^10 nuclei. Detector capabilities for charge, velocity and mass identification, estimated from ion beam tests and detailed Monte Carlo simulations, are presented. Relevant issues in cosmic ray astrophysics addressed by AMS-02, including the test of cosmic ray propagation models, galactic confinement times and the influence of solar cycles on the local cosmic ray flux, are briefly discussed.

Lossless Intra Coding in HEVC with Integer-to-Integer DST

description: It is desirable to support efficient lossless coding within video coding standards, which are primarily designed for lossy coding, with as little modification as possible. A simple approach is to skip transform and quantization, and directly entropy code the prediction residual, but this is inefficient for compression. A more efficient and popular approach is to process the residual block with DPCM prior to entropy coding. This paper explores an alternative approach based on processing the residual block with integer-to-integer (i2i) transforms. I2i transforms map integers to integers, however, unlike the integer transforms used in HEVC for lossy coding, they do not increase the dynamic range at the output and can be used in lossless coding. We use both an i2i DCT from the literature and a novel i2i approximation of the DST. Experiments with the HEVC reference software show competitive results.

description: We report on a high temperature perturbation expansion study of the superfluid-density spatial correlation function of a Ginzburg-Landau-model superconducting film in a magnetic field. We have derived a closed form which expresses the contribution to the correlation function from each graph of the perturbation theory in terms of the number of Euler paths around appropriate subgraphs. We have enumerated all graphs appearing out to 10-th order in the expansion and have evaluated their contributions to the correlation function. Low temperature correlation functions, obtained using Padé approximants, are in good agreement with Monte Carlo simulation results and show that the vortex-liquid becomes strongly correlated at temperatures well above the vortex solidification temperature.

Refinement Types for Logical Frameworks

description: The logical framework LF and its metalogic Twelf can be used to encode and reason about a wide variety of logics, languages, and other deductive systems in a formal, machine-checkable way. Recent studies have shown that ML-like languages can profitably be extended with a notion of subtyping called refinement types. A refinement type discipline uses an extra layer of term classification above the usual type system to more accurately capture certain properties of terms. I propose that adding refinement types to LF is both useful and practical. To support the claim, I exhibit an extension of LF with refinement types called LFR,work out important details of itsmetatheory, delineate a practical algorithmfor refinement type reconstruction, andpresent several case studies that highlight the utility of refinement types for formalized mathematics. In the end I find that refinement types and LF are a match made in heaven: refinements enable many rich new modes of expression, and the simplicity of LF ensures that they come at a modest cost.

description: We prove a no-go theorem for the construction of a Galilean boost invariant and $z\neq2$ anisotropic scale invariant field theory with a finite dimensional basis of fields. Two point correlators in such theories, we show, grow unboundedly with spatial separation. Correlators of theories with an infinite dimensional basis of fields, for example, labeled by a continuous parameter, do not necessarily exhibit this bad behavior. Hence, such theories behave effectively as if in one extra dimension. Embedding the symmetry algebra into the conformal algebra of one higher dimension also reveals the existence of an internal continuous parameter. Consideration of isometries shows that the non-relativistic holographic picture assumes a canonical form, where the bulk gravitational theory lives in a space-time with one extra dimension. This can be contrasted with the original proposal by Balasubramanian and McGreevy, and by Son, where the metric of a $d+2$ dimensional space-time is proposed to be dual of a $d$ dimensional field theory. We provide explicit examples of theories living at fixed point with anisotropic scaling exponent $z=\frac{2\ell}{\ell+1}\,,\ell\in \mathbb{Z}$

description: The static stationary axially symmetric background ("infinite cosmic string") of the $D=4$ string theory provided with an axion charge is studied in the effective theory approach. The most general exact solution is constructed. It is found that the Kalb-Ramond axion charge, present in the string topology $R^{3} \times S^{1}$, produces nontrivial gravitational field configurations which feature horizons. The corresponding ``no-hair'' theorems are proved which stress uniqueness of black strings. Connection of the solutions with the gauged WZWN sigma model constructions on the world sheet is discussed since they are the only target spaces which hide their singularities behind horizons, and thus obey the cosmic censorship conjecture.

description: International aviation and ocean shipping are significant and potentially fast growing sources of greenhouse gas emissions. Both sectors also contribute to poor local and regional air quality. This thesis analyzes three interventions aimed at reducing air emissions from airplanes and ships. The first is the use of tugs, or an electric motor embedded in the landing gear, to propel the aircraft on the ground. If airlines were to tow all large narrowbody aircraft on domestic service from the gate to the edge of the runway before take off at 41 of the 50 busiest airports in the U.S., CO2 emissions would fall by 0.5 million tonnes annually. In addition, the switch would produce $150 million in annual air quality benefits from reduced emissions of particulate matter, hydrocarbons and the oxides of nitrogen. Using embedded electric motors to taxi large narrowbody aircraft would cut CO2 emissions by nearly 2 million tonnes per year. The second intervention is the market based mechanism, designed to cap CO2 emissions from international aviation at 2020 levels, currently being designed at ICAO. An analysis of an early draft of this mechanism suggests that it would require airlines to offset an average of 270 million tonnes in CO2 emissions during each of the years between 2021 and 2035 when it will be active. The analysis suggests that the current proposal is complex, and poorly specified. We recommend that the mechanism be made much simpler: for example, by simply determining an airline’s offset obligations on the basis of its carbon footprint in that year. Finally, we study the costs and benefits of a more widespread use of grid electricity to energize berthed vessels. We use mixed-integer linear programming to identify combinations of ports and vessels where using shore power would produce the greatest benefit to society. We conclude that the practice could reduce CO2 emissions by 0.2 million tonnes per year and yield air quality improvements worth $80-200 million per year at no net cost to society.

description: We present new dynamical models of dwarf spheroidal galaxies (dSphs) in which both the stellar component and the dark halo are described by analytic distribution functions that depend on the action integrals. In their most general form these distribution functions can represent axisymmetric and possibly rotating stellar systems. Here, as a first application, we model the Fornax dSph, limiting ourselves, for simplicity, to the non rotating, spherical case. The models are compared with state-of-the-art spectroscopic and photometric observations of Fornax, exploiting the knowledge of the line-of-sight velocity distribution of the models and accounting for the foreground contamination from the Milky Way. The model that best fits the structural and kinematic properties of Fornax has a cored dark halo, with core size $r_{\rm c}\simeq1.03$ kpc. The dark-to-luminous mass ratio is $(M_{\rm dm}/M_{\star})|_{R_{\rm eff}}\simeq9.6$ within the effective radius $R_{\rm eff} \simeq 0.62\,$kpc and $(M_{\rm dm}/M_{\star})|_{3 {\rm kpc}} \simeq 144$ within 3 kpc. The stellar velocity distribution is isotropic almost over the full radial range covered by the spectroscopic data and slightly radially anisotropic in the outskirts of the stellar distribution. The dark-matter annihilation $J$-factor and decay $D$-factor are, respectively, $\log_{10}(J$ $[$GeV$^2$ cm$^{-5}])\simeq18.34$ and $\log_{10}(D$ $[$GeV cm$^{-2}])\simeq18.55$, for integration angle $θ= 0.5^{\circ}$. This cored halo model of Fornax is preferred, with high statistical significance, to both models with a Navarro, Frenk and White dark halo and simple mass-follows-light models.

description: The Streaming Instability (SI) is a mechanism to concentrate solids in protoplanetary disks. Nonlinear particle clumping from the SI can trigger gravitational collapse into planetesimals. To better understand the numerical robustness of the SI, we perform a suite of vertically-stratified 3D simulations with fixed physical parameters known to produce strong clumping. We vary the numerical implementation, namely the computational domain size and the vertical boundary conditions (vBCs), comparing newly-implemented outflow vBCs to the previously-used periodic and reflecting vBCs. We find strong particle clumping by the SI is mostly independent of the vBCs. However, peak particle densities are higher in larger simulation domains due to a larger particle mass reservoir. We report SI-triggered zonal flows, i.e., azimuthally-banded radial variations of gas pressure. These structures have low amplitudes, insufficient to halt particle radial drift, confirming that particle trapping in gas pressure maxima is not the mechanism of the SI. We find that outflow vBCs produce artificially large gas outflow rates at vertical boundaries. However, the outflow vBCs reduce artificial reflections at vertical boundaries, allowing more particle sedimentation, and showing less temporal variation and better convergence with box size. The radial spacing of dense particle filaments is $\sim0.15$ gas scale heights ($H$) for all vBCs, which sets the feeding zone for planetesimal growth in self-gravitating simulations. Our results validate the use of the outflow vBCs in SI simulations, even with vertical boundaries close ($\leq 0.4H$) to the disk midplane. Overall, our study demonstrates the numerical robustness of nonlinear particle clumping by the SI.

description: The U.S. electric power sector is in the early stages of transitioning from a reliance on carbon intensive generation sources to a system based on low-carbon sources. In this thesis, I present analyses of four different aspects of this transition, with an emphasis on the PJM Interconnection. The effects of bulk electricity storage on the PJM market I analyze the value of three storage technologies in the PJM day-ahead energy market, using a reduced-form unit commitment model with 2010 data. I find that large-scale storage would increase overall social welfare in PJM. However, the annualized capital costs of storage would exceed social welfare gains. Consumers would save up to $4 billion annually, largely at the expense of generator surplus. Storage modestly increases emissions of CO2 and other pollutants. The external costs and benefits of wind energy in PJM Large deployments of wind create external costs and benefits that are not fully captured in power purchase agreements. I find that wind’s external costs in the PJM market are uncertain but significant when compared to levelized PPA prices. Pollution reduction benefits are very uncertain but exceed external costs with high probability. The climate and health effects of a USA switch from coal to gas electricity generation I analyze the emission benefits created by a hypothetical scenario in which all U.S. coal plants are switched to natural gas plants in 2016. The net effect on warming is unclear; results are highly sensitive to the rate of fugitive methane emissions and the efficiency of replacement gas plants. However, the human health benefits of such a switch are substantial. The costs of building and operating new gas plants likely exceed the health benefits. Robust resource adequacy planning in the face of coal retirements Over the next decade, many U.S. coal-fired power plants are expected to retire, posing a challenge to system planners. I investigate the resource adequacy requirements of the PJM Interconnection, and how procuring less capacity may affect reliability. I find that PJM’s 2010 reserve margin of 20.5% was sufficient to achieve the stated reliability standard with 90% confidence. PJM could reduce reserve margins to 13% and still achieve levels of reliability accepted by other power systems.

description: The nonlocal response of chiral electron fluid in a semi-infinite Weyl semimetal slab with the electric current source and drain attached to its surface is studied by using the consistent hydrodynamic framework. It is found that the Chern-Simons terms lead to a spatial asymmetry of the electron flow and the electric field. Most remarkably, the corresponding topological terms could result in a negative nonlocal resistance. In addition, they give rise to the anomalous Hall current, which is sensitive to the spatial distribution of the electric field in the plane of the contacts and depends on the orientation of the chiral shift.

description: In order to support a multi-standard platform using a Software Defined Radio (SDR), the novel idea of reconfigurable Radio Frequency (RF) frontends have recently been proposed by the U.S. Defense Advanced Research Projects Agency (DARPA). A reconfigurable RF front-end has RF components that are reconfigured separately in order to satisfy the requirement of a particular communication standard. The reconfigurable RF front-end is a more reliable front-end for SDR than the currently used fixed wide-band RF front-ends, which have degraded system performance by passing more interference signals spread out in a wide range of frequency band. In order to realize the reconfigurable RF front-end, this thesis investigates the optimization method to select from the available configurations in radio environments with interference. In order to select an optimal configuration, we propose the Environment-Adaptable Fast (EAF) optimization algorithm for a reconfigurable RF front-end. A reconfigurable RF front-end not only needs to select an appropriate configuration that can operate for a given standard, but also needs to adapt quickly to a dynamic communication condition. This is difficult since there may be millions of available configurations. First, we studied RF impairment estimation for reconfigurable RF front-ends. Nonlinearity, phase noise, noise figure as well as frequency offset are RF impairments most likely to affect a particular standard. Second, we formulated the Signal-to-Interference-and-Noise Ratio (SINR) calculation which hastens the optimization process. We demonstrate the performance of the EAF optimization method in an exemplary scenario using Matlab Simulink. Finally, we designed the EAF optimization algorithm as a heuristic to select a configuration from the available ones. These simulation results demonstrate that while finding an optimal configuration, the EAF optimization significantly reduces simulation time compared to the four other previously proposed optimization methods. Thus, we expect that a reconfigurable RF front-end would be useful in real-time communication environments, since it would need significantly fewer reconfigurations to find an adequate configurations.

description: We calculate a pump current in a classical two-state stochastic chemical kinetics by means of the non-adiabatic geometrical phase interpretation. The two-state system is attached to two particle reservoirs, and under a periodic perturbation of the kinetic rates, it gives rise to a pump current between the two-state system and the absorbing states. In order to calculate the pump current, the Floquet theory for the non-adiabatic geometrical phase is extended from a Hermitian case to a non-Hermitian case. The dependence of the pump current on the frequency of the perturbative kinetic rates is explicitly derived, and a stochastic resonance-like behavior is obtained.

description: OA movement is very helpful for developing country like India where society lacks free access to research information and is unable to afford sufficient subscriptions to journals. India's premier R&D organizations such as CSIR, DBT and DST have adopted OA policies to support the OA movement. However, the absence of proper initiatives, mindset of researchers, unavailability of dedicated IT resources, undefined standard practices and lack of skill set were the bottlenecks in the implementation of OA policies for these organizations. This presentation discusses a case study of conceptualization and implementation of two Central Platforms for hosting Open Repositories and Harvester services namely "CSIR-Central" and "Science-Central". This has helped CSIR, DBT and DST to overcome the initial barriers. These platforms provide repository-as-a-service, thereby, activities such as configuration, UI customization, support, maintenance, and backup are taken care centrally. The participating institutes need not worry about technical aspects and focus only on the content development and review processes on their respective IR. Case study presents status of 30 IRs hosted on these platforms and their global visibility and shows that despite of crossing initial hurdles, the true success of these initiatives depends on the content enrichment and exploitation of services by various stakeholders.

description: In this paper we consider a generalized diffusion equation on a square lattice corresponding to Mellin transforms of the $k$-path Laplacian. In particular, we prove that superdiffusion occurs when the parameter $s$ in the Mellin transform is in the interval $(2,4)$ and that normal diffusion prevails when $s>4$.

record description

description: In 2018, the University of the Pacific Libraries worked with a faculty member in the School of Engineering and Computer Science to upload a class project involving multi-file records to the institutional repository. One of the file types was an .EXE executable Virtual Reality (VR) application. This was a first at the institution and in my experience with institutional repositories; I was stymied on how to describe and provide metadata for the VR piece – to both human and machine audiences. Attempting to read up on best practices and query the community didn't result in much concrete assistance and we muddled through as best we could. Since the first project occurred, I have continued to research standards and best practices regarding hosting and describing virtual reality, augmented reality, etc., file types in an open repository. We will also be facing this problem again as the faculty member will repeat the course and the project and wants to continue using the repository as a host. Interested? Come learn about what I did and what I've discovered along the way.

description: We investigate the low-energy spectrum of excitations of a compressible electron liquid in a strong magnetic field. These excitations are localized at the periphery of the system. The analysis of a realistic model of a smooth edge yields new branches of acoustic excitation spectrum in addition to the well known edge magnetoplasmon mode. The velocities are found and the observability conditions are established for the new modes.

description: In June 2018 the KU Leuven Association launched a new institutional repository, Lirias 2.0 (Leuven Institutional Repository and Information Archiving System). It was an ambitious project in collaboration with several stakeholders and a complex integration of various tools and infrastructures. The main goal was to ensure that the content and the repository components were interoperable, that they could connect with other systems and that it would be possible to transfer data. Furthermore, we wanted to create a stable environment in which data could be stored and accessed long-term. After a European tender procedure for the renewal of the old Lirias, KU Leuven selected 'Elements' (of the British company Symplectic, part of Digital Science) as the new publication management system. The long-term storage of the full text publications occurs in DSpace. In this presentation, we will give a functional and technical overview of the old and new version of our repository. We will also discuss the benefits and challenges of our project and describe the changes we had to make to our DSpace repository.

description: We investigate the nature of the ground ring of c=1 string theory at the special A-D-E points in the c=1 moduli space associated to discrete subgroups of SU(2). The chiral ground rings at these points are shown to define the A-D-E series of singular varieties introduced by Klein. The non-chiral ground rings relevant to closed-string theory are 3 real dimensional singular varieties obtained as U(1) quotients of the Kleinian varieties. The unbroken symmetries of the theory at these points are the volume-preserving diffeomorphisms of these varieties. The theory of Kleinian singularities has a close relation to that of complex hyperKahler surfaces, or gravitational instantons. We speculate on the relevance of these instantons and of self-dual gravity in c=1 string theory.

Recognition and Modeling of Planar Mechanical Linkages from Images Using Symbolic and Behavioral Cues

Publisher: name: Carnegie Mellon University
Year: 2015
Subjects: subject: Mechanical Engineering
subject: FOS: Mechanical engineering

description: From windshield wipers to selfie sticks, many of the machines and consumer products we use rely on mechanical linkages to accomplish functional goals. Even though we observe the dynamic behavior of these mechanisms on a daily basis, during the design and analysis of such systems, the visual content is largely static. Students may be forced to grapple with abstract depictions found in textbooks, and engineers may use hand-drawn sketches to brainstorm design ideas. Current software tools are ill-suited for fast kinematic visualization of mechanical designs and may require expertise that hinders novice users. With that in mind, the goal of this work is to create a computational method capable of quickly generating accurate kinematic models from images of planar mechanical linkages. Despite remarkable progress in recent years for computer vision tasks such as object recognition, scene understanding, and image segmentation, the problem of identifying a collection of connected parts with unknown structure in an image is a challenging one. Our framework leverages supervised learning methods for localizing mechanical parts (e.g. joints, rigid bodies) with the optimizing power of a multiobjective evolutionary algorithm for predicting feasible topologies. We systematically evaluate each stage of our framework and introduce a novel metric called the user effort ratio to compare the overall performance of different algorithms and assess the benefit of automatic recognition over manual model construction. The final outcome is a standalone software application that takes a raw image as input and produces a kinematic simulation of the pictured mechanism with minimal user interaction.
Defect-induced modification of low-lying excitons and valley selectivity in monolayer transition metal dichalcogenides

description: We study the effect of point-defect chalcogen vacancies on the optical properties of monolayer transition metal dichalcogenides using ab initio GW and Bethe-Salpeter equation calculations. We find that chalcogen vacancies introduce unoccupied in-gap states and occupied resonant defect states within the quasiparticle continuum of the valence band. These defect states give rise to a number of strongly-bound defect excitons and hybridize with excitons of the pristine system, reducing the valley-selective circular dichroism. Our results suggest a pathway to tune spin-valley polarization and other optical properties through defect engineering.
