Publisher: name: arXiv

description: We consider the quantum Hall effect of two-dimensional electrons with a periodic potential and study the time dependence of the Hall and longitudinal currents when the electric field is applied abruptly. We find that the currents oscillate in time with very large frequencies because of quantum fluctuation and the oscillations eventually vanish, for their amplitudes decay as 1/t.

description: Find more information about the Text Encoding Initative at https://tei-c.orgTEI P5 version 2.9.0 release notesThis version of the TEI Guidelines introduces new features and resolves a number of issues raised by the TEI community. As always, the majority of these changes and corrections are a consequence of feature requests or bugs reported by the TEI community using the Github tracking system. If you find something you think needs to change in the TEI Guidelines, schemas, tools, or website, please submit a feature request or bug issue at https://github.com/TEIC/TEI/issues for consideration. Lists of closed bugs and closed feature requests are available on the site. Some of the more noticeable changes in this release include: Probably the most significant change in this release involves no real change to the Guidelines themselves, but a big shift in the way their development and publication proceeds. The TEI Guidlines are now hosted on Github. This has entailed significant changes to our testing and release processes and will, we hope, make it both easier for us to develop the Guidelines and easier for the TEI community to engage with their development. This change, and the associated work has unfortunately meant a delay in the release of two major new features: the Pure ODD content model revision and TEI Simple, which depends on Pure ODD. We plan to release these features before the end of 2015. A new element has been added, xenoData, which provides encoders with a place to put non-TEI data they wish to embed in TEI documents. See https://github.com/TEIC/TEI/issues/453. The critical apparatus elements lem and rdg may now contain structural elements, such as l, p, and div, allowing the creators of critical editions to describe textual variation at the structural level. See https://github.com/TEIC/TEI/issues/522 and https://github.com/TEIC/TEI/issues/1322. A new element to mark text secluded by an editor, secl was added, per https://github.com/TEIC/TEI/issues/531. The event element is now allowed in org, per https://github.com/TEIC/TEI/issues/616. The element hi is now permitted inside m, per https://github.com/TEIC/TEI/issues/556. The deprecated status attribute was removed from att.identified. Added a new selector attribute on rendition, per https://github.com/TEIC/TEI/issues/520. The deprecated degree attribute on precision has been removed. See https://github.com/TEIC/TEI/issues/468 and https://github.com/TEIC/TEI/issues/1324. And, of course, many typos were corrected. In addition, improvements have been made to the XSL stylesheets (which provide processing of TEI ODD files for Roma and OxGarage as well as other TEI conversions). The Stylesheets are maintained separately from the Guidelines and are at https://github.com/TEIC/Stylesheets. Home Feedback Date: 2015-10-09

Radiation Transfer in Gamma-Ray Bursts

Year: 1992
Subjects: subject: Astrophysics (astro-ph)

description: We have calculated gamma-ray radiative transport in regions of high energy density, such as gamma-ray burst source regions, using a discrete ordinate, discrete energy group method. The calculations include two-photon pair production and annihilation, as well as three-photon pair annihilation. The radiation field itself acts as an absorbing medium, and the optical depth depends on its intensity, so the problem is intrinsically nonlinear. Spherical divergence produces effective collimation of the flux. At high optical depth the high energy ($E > 1$ MeV) portion of the emergent spectrum assumes a nearly universal form. An approximate limit is derived for the high energy flux from a gamma-ray burst source region of given size, and the implications of this limit for the distance to the March 5, 1979 event are briefly discussed. We discuss more generally the problem of very luminous bursts, and implications of Galactic halo distances for flare models.

description: Moitvated in part by [3], in this note we obtain a rigidity result for globally hyperbolic vacuum spacetimes in arbitrary dimension that admit a timelike conformal Killing vector field. Specifically, we show that if M is a Ricci flat, timelike geodesically complete spacetime with compact Cauchy surfaces that admits a timelike conformal Killing field X, then M must split as a metric product, and X must be Killing. This gives a partial proof of the Bartnik splitting conjecture in the vacuum setting.

description: In this paper we consider the dynamics of point islands during submonolayer deposition, in which the fragmentation of subcritical size islands is allowed. To understand asymptotics of solutions, we use methods of centre manifold theory, and for globalisation, we employ results from the theories of compartmental systems and of asymptotically autonomous dynamical systems. We also compare our results with those obtained by making the quasi-steady state assumption.

description: The topic I have been asked to address — the principles guiding the choice of a monetary regime or constitution — has remained an unresolved issue in the theories of money and economic policy. The student of money confronts four formidable obstacles when addressing this issue as an application of economic theory. First, money is not only neutral in monetary theory, but it is one of many, undifferentiated commodities without any particular properties that can affect the economy's equilibrium. Any commodity chosen at random provides money services as well as any other. Second, although the choice of monetary institutions or a monetary standard can have real effects in practice, these effects are excluded from formal economic theory by the assumption of continuous market clearing and by making the competitive equilibrium independent of real world institutions. Third, relevant aspects of uncertainty that give rise to costly information are missing. At most, individuals hold certain expectations about all possible future contingencies. Fourth, a representative agent makes all decisions, bears all costs, and receives all benefits. There are no effects of redistribution through inflation or deflation. In this framework the choice of a monetary constitution is uninteresting.
Stimuli Thresholds for Isomerization-induced Molecular Motions in Azobenzene Containing Materials

Year: 2017
Subjects: subject: Soft Condensed Matter (cond-mat.soft)

description: We use large scale molecular dynamics simulations of the isomerizations of azobenzene molecules diluted inside a simple molecular material, to investigate the effect of a modification of the cis isomer shape on the induced diffusion mechanism. To this end we simulate incomplete isomerizations, modifying the amplitude of the trans to cis isomerization. We find thresholds in the evolution of the host molecules mobility with the isomerization amplitude, a result predicted by the cage- breaking mechanism hypothesis (Teboul, V.; Saiddine, M.; Nunzi, J.M.; Accary, J.B. J. Chem. Phys. 2011, 134, 114517) and by the gradient pressure mechanism theory (Barrett, C.J.; Rochon, P.L.; Natansohn, A.L. J. Chem. Phys. 1998, 109, 1505-1516. ). Above the threshold the diffusion then increases linearly with the variation of the chromophore size induced by the isomerization.

description: The spontaneous breakdown of the scale, the chiral and the superconformal symmetries for a hidden $SU(N)$ gauge group is studied in an effective lagrangean approach. The relevant low-energy degrees of freedom are taken to be the composite Goldstone particles associated with these three broken symmetries. Supersymmetry is spontaneously broken in the large $N$ limit and soft breaking terms in the observable sector are generated, together with nonrenormalisable Nambu-Jona-Lasinio type interactions.

Inside Type Iax supernovae: to the photosphere and beyond
Creators: name: Camacho-Neves, Yssavo
Publisher: name: No Publisher Supplied
Year: 2023

description: Type Iax supernovae (SNe Iax) are the largest known class of peculiar white dwarf supernovae,distinct from normal Type Ia supernovae (SNe Ia). The unique spectral properties of SNe Iax, especially their remarkably low velocities and strong photospheric lines out to extremely late times, are a special tool we can use to look inside this violent thermonuclear explosion. This thesis explores the physical properties of SNe Iax using high-cadence spectral observations, which allow us to constrain not just how, but exactly when, and how fast important physical parameters change over time. We present an extensive spectral timeseries of SN 2014dt from +11 to +562 days after maximumlight (Camacho-Neves et al. 2023). We are able to reproduce the entire timeseries with a self-consistent, nearly unaltered deflagration explosion model from Fink et al. (2014) using TARDIS, an open-source radiative transfer code (Kerzendorf & Sim 2014; Kerzendorf et al. 2023). We find that the photospheric velocity of SN 2014dt slows its evolution between +64 and +148 days, which closely overlaps the phase when we see SN 2014dt diverge from the normal spectral evolution of SNe Ia (+90 to +150 days). The photospheric velocity at these epochs, ∼400–1000 km s−1, may demarcate a boundary within the ejecta below which the physics of SNe Iax and normal SNe Ia differ. Our results suggest that SN 2014dt is consistent with a weak deflagration explosion model that leaves behind a bound remnant and drives an optically thick, quasi-steady-state wind creating the photospheric lines at late times. The data also suggest that this wind may weaken at epochs past +450 days, perhaps indicating a radioactive power source that has decayed away. We also present a large late-time spectral timeseries of SN 2019muj ranging from +102 to +463 days past maximum light. We find that SN 2019muj is generally consistent with post-SNe Iax wind models from Shen & Schwab (2017), with Ca and Fe lines tracing similar material at and above the photosphere. We also find that the density decreases faster over time in SN 2019muj than in other SNe Iax, pointing to diversity within the class. Overall, our spectral analyses of SN 2014dt andSN 2019muj suggest that both objects may have radioactively powered winds from post-explosion bound remnants, though the strength and evolution of the winds may vary.
Algorithms, Bounds, and Strategies for Entangled XOR Games

description: We study the complexity of computing the commuting-operator value $ω^*$ of entangled XOR games with any number of players. We introduce necessary and sufficient criteria for an XOR game to have $ω^* = 1$, and use these criteria to derive the following results: 1. An algorithm for symmetric games that decides in polynomial time whether $ω^* = 1$ or $ω^* < 1$, a task that was not previously known to be decidable, together with a simple tensor-product strategy that achieves value 1 in the former case. The only previous candidate algorithm for this problem was the Navascués-Pironio-Acín (also known as noncommutative Sum of Squares or ncSoS) hierarchy, but no convergence bounds were known. 2. A family of games with three players and with $ω^* < 1$, where it takes doubly exponential time for the ncSoS algorithm to witness this (in contrast with our algorithm which runs in polynomial time). 3. A family of games achieving a bias difference $2(ω^* - ω)$ arbitrarily close to the maximum possible value of $1$ (and as a consequence, achieving an unbounded bias ratio), answering an open question of Briët and Vidick. 4. Existence of an unsatisfiable phase for random (non-symmetric) XOR games: that is, we show that there exists a constant $C_k^{\text{unsat}}$ depending only on the number $k$ of players, such that a random $k$-XOR game over an alphabet of size $n$ has $ω^* < 1$ with high probability when the number of clauses is above $C_k^{\text{unsat}} n$. 5. A lower bound of $Ω(n \log(n)/\log\log(n))$ on the number of levels in the ncSoS hierarchy required to detect unsatisfiability for most random 3-XOR games. This is in contrast with the classical case where the $n$-th level of the sum-of-squares hierarchy is equivalent to brute-force enumeration of all possible solutions.

On Keynes and Monetarism

description: It is an honor to be invited to speak at a conference honoring Keynes. His work has probably stimulated more pages of analysis, discussion and controversy than the work of any other economist.* Many of the controversies proved sterile, but others have had lasting effects and some continue to shape economics. The particular controversy about which I have been asked to speak - the monetarist controversy - remains one of the more productive controversies. The controversy stimulated developments in micro and macro economics, in econometrics, in the theory of expectations and the relation of expectations to econometrics and to micro and macro economics. At times, some disputants ignore these gains and appear to see only retrogression where there is progress. Kaldor (1982) is one example, but an example familiar to this audience. Other economists, who undertake to read the literature - though highly critical of recent developments and distressed by their policy implications - recognize that the monetarist controversy has caused them to rethink and change their views - Modigliani (1977) - and, more importantly, has caused lasting changes in economic theory - Tobin (1981, pp. 41-2). I take as given and obvious that both monetarism and our understanding of Keynes1 theory continue to change, the former because it is part of economic science, the latter to considerable degree as a result of the excellent volumes containing Keynes' papers and letters produced for the Royal Economic Society

description: Helen Rosenau war eine Kunsthistorikerin und Archäologin, die 1933 nach der Machtübernahme der Nationalsozialisten aus Deutschland nach England flüchten musste. Nach ihrer Emigration befand sie sich, wie zahlreiche weitere jüdische Wissenschaftlerinnen und Wissenschaftler, in einer prekären Situation. In ihren Veröffentlichungen wurde nun erstmals eine deutliche politische Positionierung sichtbar. 1942 schrieb sie den vorliegenden Artikel für die Veröffentlichung „Women under the Swastika“, Frauen unter dem Hakenkreuz, im Rahmen der „Free German League of Culture in Great Britain“, dem Freien deutschen Kulturbund in Großbritannien, einer Organisation von Emigrierten. Der Bund verstand sich als eine überparteiliche Flüchtlingsorganisation, die sich der Vermittlung von deutscher Kultur verschrieben hatte. Dieser Bund stand der KPD nahe. Dennoch erfüllte er für viele, auch nicht kommunistische, Geflüchtete in England eine wichtige Aufgabe. In ihrer Veröffentlichung setzte sich Rosenau mit der Rolle von Frauen im nationalsozialistischen Deutschland auseinander und skizzierte die Entwicklung eines deutschen Feminismus. Hierbei übertrug sie Friedrich Schleiermachers „Idee zu einem Katechismus für edle Frauen“ von 1798 ins Englische und verglich diese Vorstellungen mit der Realität von Frauen im Nationalsozialismus. Rosenau äußerte die Hoffnung, dass die deutsche feministische Bewegung in Zukunft wieder auferstehen möge.

description: We study some basic quantum confinement effects through investigation a deformed harmonic oscillator algebra. We show that spatial confinement effects on a quantum harmonic oscillator can be represented by a deformation function within the framework of nonlinear coherent states theory. Using the deformed algebra, we construct a quantum field theory in confined space. In particular, we find that the confinement influences on some physical properties of the electromagnetic field and it gives rise to nonlinear interaction. Furthermore, we propose a physical scheme to generate the nonlinear coherent states associated with the electromagnetic field in a confined region.

description: Recent experiments on electron- or hole-doped SrTiO$_{3}$ have revealed a hitherto unknown form of superconductivity, where the Fermi energy of the paired electrons is much lower than the energies of the bosonic excitations thought to be responsible for the attractive interaction. We show that this situation requires a fresh look at the problem calling for (i) a systematic modeling of the dynamical screening of the Coulomb interaction by ionic and electronic charges, (ii) a transverse optical phonon mediated pair interaction and (iii) a determination of the energy range over which the pairing takes place. We argue that the latter is essentially given by the limiting energy beyond which quasiparticles cease to be well defined. The model allows to find the transition temperature as a function of both, the doping concentration and the dielectric properties of the host system, in good agreement with experimental data. The additional interaction mediated by the transverse optical soft phonon is shown to be essential in explaining the observed anomalous isotope effect. The model allows to capture the effect of the incipient (or real) ferroelectric phase in pure, or oxygen isotope substituted SrTiO$_{3}$ .

description: Helen Rosenau was an art historian and archaeologist who had to flee Germany for England in 1933 after the Nazis came to power. After her emigration, she, like numerous other Jewish scholars, found herself in a precarious situation. In her publications, a clear political positioning now became visible for the first time. In 1942, she wrote the present article for the publication „Women under the Swastika“ published by the Free German League of Culture in Great Britain Freier deutscher Kulturbund in Großbritannien, an organization of emigrants. The League saw itself as a non-partisan refugee organization dedicated to teaching German culture. It was close to the German Communist Party (KPD). Nevertheless, it fulfilled an important task for many, even non-Communist, refugees in England. In her publication, Rosenau examined the role of women in National Socialist Germany and outlined the development of a German feminism. In doing so, she translated Friedrich Schleiermacher's 1798 “Idea for a Catechism for Noble Women” into English and compared these ideas to the reality of women under National Socialism. Rosenau expressed the hope that the German feminist movement would be resurrected in the future.

description: Dust is observed to form in nova ejecta. The grain temperature is determined by the diluted nova radiation field rather than the gas kinetic temperature, making classical nucleation theory inapplicable. We used kinetic equations to calculate the growth of carbon nuclei in these ejecta. For expected values of the parameters too many clusters grew, despite the small sticking probability of atoms to small clusters, and the clusters only reached radii of about 100Å when the carbon vapor was depleted. We then included the effects of cluster photodissociation by ultraviolet radiation from the nova. This suppresses nucleation, but too well, and no grains form at all. Finally we suggest that a few growing carbon nuclei may be protected from photodissociation by a sacrificial surface layer of hydrogen.

description: Hydrogel, with excellent hydrophilicity biocompatibility and stimuli responsive, has been widely used in biomedical and artificial organs fields. However, synthetic hydrogel usually displays poor gel strength, poor toughness and slow speed of absorbing water. Therefore, extensive exploratory research is still required to develop new composite materials for the application of bionic viscera. In this work, we constructed a new kind of composite hydrogel by a facile wet chemistry method to cross-link three kinds of polymer resin, polyvinyl alcohol, carboxymethyl cellulose, and carboxymethyl starch. The conductivity, moisture content and elastic modulus of hydrogel can be controlled by the dosage of potassium salt, sodium salt, water and glycerol. After molding and testing, the electrical conductivity, elastic modulus, and moisture content of the artificial liver and kidney organs were similar to those of the corresponding pig viscera, which is superior to most of the current research on hydrogels. This work provides a facile approach to synthesize highly efficient hydrogel, which accelerates the application of hydrogel in bionic organs.

description: We consider T--shaped, two--dimensional quantum waveguides containing attractive or repulsive impurities with a smooth, realistic shape, and study how the resonance behavior of the total conductance depends upon the strength of the defect potential and the geometry of the device. The resonance parameters are determined locating the relevant S-matrix poles in the Riemann energy surface. The total scattering operator is obtained from the S-matrices of the various constituent segments of the device through the *-product composition rule. This allows for a numerically stable evaluation of the scattering matrix and of the resonance parameters.

description: Precise and absolute beam polarization measurements are critical for the RHIC spin physics program. Because all experimental spin-dependent results are normalized by beam polarization, the normalization uncertainty contributes directly to final physics uncertainties. We aimed to perform the beam polarization measurement to an accuracy of $ΔP_{beam}/P_{beam} < 5%$. The absolute polarimeter consists of Polarized Atomic Hydrogen Gas Jet Target and left-right pairs of silicon strip detectors and was installed in the RHIC-ring in 2004. This system features \textit{proton-proton} elastic scattering in the Coulomb nuclear interference (CNI) region. Precise measurements of the analyzing power $A_N$ of this process has allowed us to achieve $ΔP_{beam}/P_{beam} =4.2%$ in 2005 for the first long spin-physics run. In this report, we describe the entire set up and performance of the system. The procedure of beam polarization measurement and analysis results from 2004-2005 are described. Physics topics of $A_N$ in the CNI region (four-momentum transfer squared $0.001 < -t < 0.032 ~ ({\rm GeV}/c)^2$) are also discussed. We point out the current issues and expected optimum accuracy in 2006 and the future.

Nonstationary Gravitational Lenses and the Fermat Principle

description: We apply Perlick's (1990a) rigorous formulation of the Fermat principle in arbitrary spacetimes to prove the correctness of the description of gravitational lensing by gravitational waves, given in the literature using the scalar and vector formalisms. We obtain an expression for the time delay due to such nonstationary lenses; the advantage over previous papers is that Perlick's formulation of the Fermat principle is very rigorous and more suitable for practical calculations in some cases. It is also shown that ordinary moving gravitational lenses must be considered as a stationary case.

description: Optical Character Recognition has been a challenging field in the advent of digital computers. It is needed where information is to be readable both to humans and machines. The process of OCR is composed of a set of pre and post processing steps that decide the level of accuracy of recognition. This paper deals with one of the pre-processing steps involved in the OCR process i.e. Skew (Slant) Detection and Correction. The proposed algorithm implemented for skew-detection is termed as the COG (Centre of Gravity) method and for that of skew-correction is Sub-Pixel Shifting method. The algorithm has been kept simple and optimized for efficient skew-detection and correction. The performance analysis of the algorithm after testing has been aptly demonstrated.

description: MR. SYRING (1967) suggests that I relied on assertion rather than evidence or proof to support my statement that "little bias results from the exclusion of human wealth from the measure of wealth used to test the [demand-for-money] hypothesis" (Meltzer, 1963, p. 234). Further, he finds nothing in the empirical evidence to support my assumption that the ratio (d) of income from human wealth (yh) to the stock of human wealth (wh) is constant in the long run, although he recognizes that the assumption may be correct. In this note I will show that the estimated elasticities of real money balances with respect to real income and real non-human wealth are quite consistent with my assumption that d is constant in the long run. I will then discuss the more general problem that he raises, namely, whether it is possible to distinguish empirically between income and wealth as constraints on the demand for money.

description: Electrical Impedance Tomography (EIT) is a noninvasive imaging technique that does not use ionizing radiation, with application both in environmental sciences and in health. Image reconstruction is performed by solving an inverse problem and ill-posed. Evolutionary Computation and Swarm Intelligence have become a source of methods for solving inverse problems. Fish School Search (FSS) is a promising search and optimization method, based on the dynamics of schools of fish. In this article the authors present a method for reconstruction of EIT images based on FSS and Non-Blind Search (NBS). The method was evaluated using numerical phantoms consisting of electrical conductivity images with subjects in the center, between the center and the edge and on the edge of a circular section, with meshes of 415 finite elements. The authors performed 20 simulations for each configuration. Results showed that both FSS and FSS-NBS were able to converge faster than genetic algorithms.
On Global Warming: Flow-Based Soft Global Constraints

description: In case a CSP is over-constrained, it is natural to allow some constraints, called soft constraints, to be violated. We propose a generic method to soften global constraints that can be represented by a flow in a graph. Such constraints are softened by adding violation arcs to the graph and then computing a minimum-weight flow in the extended graph to measure the violation. We present efficient propagation algorithms, based on different violation measures, achieving domain consistency for the alldifferent constraint, the global cardinality constraint, the regular constraint and the same constraint.
On Families of Split Cuts that Can Be Generated Efficiently

description: Split cuts represent the most widely used class of cutting planes currently employed by state-of-the-art branch-and-cut solvers for mixed integer linear programming. Rank-1 cuts often have better numerical properties than higher rank cuts. In this paper, we study several heuristics to generate new families of strong rank-1 split cuts, by considering integer linear combinations of the rows of the simplex tableau, and deriving the corresponding mixed integer Gomory cuts. In particular, we propose several cut generation algorithms that share the following aims: reducing the number of nonzeroes, obtaining small coefficients, generating orthogonal cuts. A key idea is that of selecting a subset of the variables, and trying to generate a cut which cuts deeply on those variables. We show that variables with small reduced cost are good candidates for this purpose, yielding cuts that close a larger integrality gap. On a set of test instances where standard split cut generators close on average 28.8% of the integrality gap in the first pass, we can close 35.3% by investing 10 times as much cut generation time. Incorporating our new split cuts into a branch-and-cut algorithm yields an improvement in the overall performance: except on very easy instances, where our procedure is too slow to bring advantage, on average we can save 23% computing time on instances which are solved, and close more integrality gap on unsolved instances in a fixed amount of time.

description: We study a simple and versatile diatomic potential function coined to prevent crystallization in supercooled liquids. We show that the corresponding liquid does not crystallize even with very long simulation runs at the lowest temperature that we can access with ergodic simulations. The medium displays the usual features of supercooled materials and a non-Arrhenius dependence of the diffusion coefficient and alpha relaxation time with temperature. We also observe the breakdown of the Stokes-Einstein relation at low temperatures.

description: An outsider reading the literature on SEC regulation is struck by the contrast between the amount of space devoted to the unresolved problems created by industry practices and the paucity of material dealing with problems crated by SEC practices. Even more striking, after 30 years of regulation, is the absence of discussion of the rationale for continuing present regulations or a review of the achievements or deficiencies of past regulations. While there is considerable discussion of current proposals to extend SEC regulation into new areas, little attention is paid to the problems that would be reduced if existing regulations were changed or eliminated. One of the few attempts to present some evidence of the effects of SEC regulation on the industry, 1 produced a reaction that seems excessive, to an outsider, considering the tentative nature of the evidence presented. Indeed, a major point of the respondents seems to be that no assessment of the SEC's achievements or deficiencies is required. It is sufficient, for them, that the law and the SEC have eliminated some of the practices that previously existed.
Stability of Room Temperature Compensated Half-Metallicity in Cr-based Inverse-Heusler Compounds

description: Using three correlated band approaches, namely the conventional band approach plus on-site Coulomb repulsion $U$, the modified Becke-Johnson functional, and hybrid functional, we have investigated inverse-Heusler ferrimagnets Cr$_2$Co${\cal Z}$ (${\cal Z}$=Al, Ga, In). These approaches commonly indicate that the Cr$_2$CoAl synthesized recently is a precise compensated half-metal (CHM), whereas Cr$_2$CoGa and Cr$_2$CoIn are ferrimagnets with a small moment. This is also confirmed by the fixed spin moment approach. Analysis of the Bader charge decomposition and the radial charge densities indicates that this contrast is due to chemical differences among the ${\cal Z}$ ions. Additionally, in Cr$_2$CoAl, changing the volume by $\pm$ 5% or the ratio of $c/a$ by $\pm$ 2% does not alter the CHM state, suggesting that this state is robust even under application of moderate pressure or strain. Considering the observed high Curie temperature of 750 K, our results suggest that Cr$_2$CoAl is a promising candidate for robust high $T_C$ CHMs. Furthermore, the electronic structure of the CHM Cr$_2$CoAl is discussed.
