description: We report on the use of elliptical pump spatial modes to increase the observed brightness of spontaneous parametric downconversion in critically phase matched crystals. Simulations qualitatively predict this improvement which depends on the eccentricity and orientation of the pump ellipse. We experimentally confirm a factor of two improvement in brightness when compared to the traditional circular-symmetric pump spatial modes. These results support previous theoretical work that proposes the use of elliptical pump modes to enhance the performance of parametric processes in anisotropic materials.

description: We present the discovery of long-period, low-amplitude, g-mode pulsations in the intermediate He-rich hot subdwarf (sdOB) star Feige 46. Up until now only one other He-enriched sdOB star (LS IV -14116) was known to exhibit such pulsations. From our ground-based light curves of Feige 46, we extracted five independent periodicities ranging from 2294 s to 3400 s. We fitted our low-resolution, high signal-to-noise optical spectrum of the star with our grid of non-LTE model atmospheres and derived the following atmospheric parameters: Teff = 36120 $\pm$ 230 K, log g = 5.93 $\pm$ 0.04 and log N(He)/N(H) = -0.32 $\pm$ 0.03 (formal fitting errors only). These parameters are very similar to those of LS IV -14116 and place Feige 46 well outside of the instability strip where the hydrogen-rich g-mode sdB pulsators are found. We used the Gaia parallax and proper motion of Feige 46 to perform a kinematic analysis of this star and found that it likely belongs to the Galactic halo population. This is most certainly an intriguing and interesting result given that LS IV -14116 is also a halo object. The mechanism responsible for the pulsations in these two peculiar objects remains unclear but a possible scenario involves the $ε$-mechanism. Although they are the only two members in their class of variable stars, these pulsators appear to have more in common than just their pulsation properties.

description: We prove that in bosonic quantum mechanics the two-point spectral form factor can be obtained as an average of the two-point out-of-time ordered correlation function, with the average taken over the Heisenberg group. In quantum field theory, there is an analogous result with the average taken over the tensor product of many copies of the Heisenberg group, one copy for each field mode. The resulting formula is expressed as a path integral over two fields, providing a promising approach to the computation of the spectral form factor. We develop the formula that we have obtained using a coherent state description from the JC model and also in the context of the large-$N$ limit of CFT and Yang-Mills theory from the large-$N$ matrix quantum mechanics.

description: We view $MgB_2$ as electronically equivalent to (non-staggered) graphite ($B^-$ layer) that has undergone a zero gap semiconductor to a superconductor phase transition by a large c-axis (chemical) pressure due to $Mg^{++}$ layers. Further, like the \ppi bonded planar organic molecules, graphite is an old resonating valence bond (RVB) system. The RVB's are the `preexisting cooper pairs' in the `parental' zero gap semiconducting $B^-$ (graphite) sheets that manifests themselves as a superconducting ground state of the transformed metal. Some consequences are pointed out.

description: We propose an efficient optomechanical mass sensor operating at exceptional points (EPs), non-hermitian degeneracies where eigenvalues of a system and their corresponding eigenvectors simultaneously coalesce. The benchmark system consists of two optomechanical cavities (OMCs) that are mechanically coupled, where we engineer mechanical gain (loss) by driving the cavity with a blue (red) detuned laser. The system features EP at the gain and loss balance, where any perturbation induces a frequency splitting that scales as the square-root of the perturbation strength, resulting in a giant sensitivity factor enhancement compared to the conventional optomechanical sensors. For non-degenerated mechanical resonators, quadratic optomechanical coupling is used to tune the mismatch frequency in order to get closer to the EP, extending the efficiency of our sensing scheme to mismatched resonators. This work paves the way towards new levels of sensitivity for optomechanical sensors, which could find applications in many other fields including nanoparticles detection, precision measurement, and quantum metrology.

description: The structural and electronic properties of interfaces between beta-SiC and III-V semiconductors are studied by first-principles calculations. Favorable bonding configurations are found to form between Si-V and C-III (model A) for BN, AlN, AlP, AlAs, GaN, GaP, GaAs, InN, InP, InAs and InSb, and Si-III and C-V (model B) for BP, BAs, BSb, AlSb and GaSb. The relationship between formation energy difference and lattice constant difference as well as charge distribution for these two models is found. The origin of bonding configurations can be explained in terms of the ionicity of III-V semiconductors, electrostatic effect, charge distribution and band-structure component.

description: Caregiving in adolescence, specifically when directed towards a parent, is associated with increased depression. This study examines whether young carers caring for their parents are more likely to be depressed than those caring for other family members and non-caring youth. Using data from two waves of the Growing Up in Ireland study (N = 3,312), the above associations were examined cross-sectionally (Aged 17; T1), and longitudinally (Aged 20; T2). The role of parent and peer relationship quality in predicting depression was also examined. Compared to non-carers, carers of parents were 3.67 times more likely to be depressed at T1, but not at T2. Moreover, young carers of parents who were depressed reported lower peer attachments, as well as lower quality relationships with their parents. Logistic regression analyses showed these relationships to be predictive of depression. This research is discussed in terms of supporting young carers from a family-based perspective.

description: We report the development and application of a new method for carrying out computational investigations of the effects of mass and force-constant (FC) disorder on phonon spectra. The method is based on the recently developed typical medium dynamical cluster approach (TMDCA), which is a Green's function approach. Excellent quantitative agreement with previous exact diagonalization results establishes the veracity of the method. Application of the method to a model system of binary mass and FC-disordered system leads to several findings. A narrow resonance, significantly below the van Hove singularity, that has been termed as the boson peak, is seen to emerge for low soft particle concentrations. We show, using the typical phonon spectrum, that the states constituting the boson peak cross over from being completely localized to being extended as a function of increasing soft particle concentration. In general, an interplay of mass and FC disorder is found to be cooperative in nature, enhancing phonon localization over all frequencies. However, for certain range of frequencies, and depending on material parameters, FC disorder can delocalize the states that were localized by mass disorder, and vice-versa. Modeling vacancies as weakly bonded sites with vanishing mass, we find that vacancies, even at very low concentrations, are extremely effective in localizing phonons. Thus, inducing vacancies is proposed as a promising route for efficient thermoelectrics. Finally, we use model parameters corresponding to the alloy system, Ni1-xPtx, and show that mass disorder alone is insufficient to explain the pseudogap in the phonon spectrum; the concomitant presence of FC disorder is necessary.
Josephson current between chiral superconductors

description: We study chiral interface Andreev bound states and their influence on the Josephson current between clean superconductors. Possible examples are superconducting Sr2RuO4 and the B-phase of the heavy-fermion superconductor UPt3. We show that, under certain conditions, the low-energy chiral surface states enhance the critical current of symmetric tunnel junctions at low temperatures. The enhancement is substantially more pronounced in quantum point contacts. In classical junctions dispersive chiral states result in a logarithmic dependence of the critical current. This logarithmic behavior contains the temperature, the barrier transparency and the broadening of the bound states, and depends on the detailed relation between these parameters. The Josephson current through the domain wall doesn't acquire this logarithmic enhancement, although the contribution from the bound states is important in this case as well.

 LECTOTYPE: AMNH 691332, adult male, collected at Coopers Camp, Apsley Strait, Melville Island, Northern Territory, Australia, on 24 November 1911, by J.P. Rogers (no. 2512). From the Mathews Collection (no. 11336) via the Rothschild Collection.
 COMMENTS: In the original description, Mathews said that his type was from Melville Island, which was also given as the range of the form. AMNH 691332 bears, in addition to Rogers’ original label, Mathews and Rothschild type labels and a Mathews ‘‘Figured’’ label indicating that it was the model for Mathews (1924: pl. 511, lower figure, opp. p. 241, text p. 243), where the figured male is said to be the type of gradus, thereby designating it the lectotype. While Mathews’ catalog number is written on the type labels, it was not mentioned in the description. Mathews (1912b: 26) noted that he had received two shipments of birds collected on Melville Island prior to his description of this form. This included all of the specimens collected at Coopers Camp in 1911.There are six paralectotypes in AMNH: AMNH 691331 (Mathews no. 11337), male, 24 November; AMNH 691334 (10690), female, 3 October; AMNH 691335 (11615), female, 7 November; AMNH 691337 (11616), female, 7 November; AMNH 691338 (10689), female, 2 October; AMNH 691339 (10688), sex?, 13 October. A seventh paralectotype was cataloged by Mathews as no. 11338, male, collected 24 November 1911, but it did not come to AMNH.
Coopers Camp, according to Hart and Pilling (1964: 101), was across Apsley Strait from the Bathurst Island Mission Station, 11.45S, 130.41E (Times Atlas).

description: Using a recently introduced algorithm for simulating percolation in microcanonical (fixed-occupancy) samples, we study the convergence with increasing system size of a number of estimates for the percolation threshold for an open system with a square boundary, specifically for site percolation on a square lattice. We show that the convergence of the so-called "average-probability" estimate is described by a non-trivial correction-to-scaling exponent as predicted previously, and measure the value of this exponent to be 0.90(2). For the "median" and "cell-to-cell" estimates of the percolation threshold we verify that convergence does not depend on this exponent, having instead a slightly faster convergence with a trivial analytic leading exponent.

description: Molecular oxygen has been the subject of many observational searches as chemical models predicted it to be a reservoir of oxygen. Although it has been detected in two regions of the interstellar medium, its rarity is a challenge for astrochemical models. In this paper, we have combined the physical conditions computed with smoothed particle hydrodynamics (SPH) simulations with our full gas-grain chemical model Nautilus, to study the predicted O2 abundance in interstellar material forming cold cores. We thus follow the chemical evolution of gas and ices in parcels of material from the diffuse interstellar conditions to the cold dense cores. Most of our predicted O2 abundances are below 1e-8 (with respect to the total proton density) and the predicted column densities in simulated cold cores is at maximum a few 1e14 cm-2, in agreement with the non detection limits. This low O2 abundance can be explained by the fact that, in a large fraction of the interstellar material, the atomic oxygen is depleted onto the grain surface (and hydrogenated to form H2O) before O2 can be formed in the gas-phase and protected from UV photo-dissociations. We could achieve this result only because we took into account the full history of the evolution of the physical conditions from the diffuse medium to the cold cores.

 HOLOTYPE: AMNH 697065, adult male, collected at Utingu, Cape York, Queensland, Australia, on 13 May 1912, by Robin Kemp (no. 867). From the Mathews Collection (no. 12897) via the Rothschild Collection.
 COMMENTS: Mathews cited his catalog number of the holotype in the original description and gave the range of yorki as ‘‘Cape York.’’ The specimen bears Kemp’s original label, Mathews and Rothschild type labels, and a ‘‘Figured’’ label, indicating that this specimen was illustrated in Mathews (1925a: pl. 555, lower fig. labeled Neophilemon yorki, opp. p. 103, text p. 104), where it is confirmed as the type of yorki. The type also bears a tag annotated by Mathews: ‘‘To Gron old, Note bare skin, low down on neck;’’ this is undoubtedly a note to the artist, H. Grönvold. Only specimens collected by Kemp on Cape York in April and May 1912 were cataloged by Mathews before the publication of yorki on 18 September 1912. These four specimens are paratypes: AMNH 697066 (Mathews no. 13209), male, Utingu, 23 May; AMNH 697079 (12758), female, Thursday Island (but cataloged as Cape York), 30 April; AMNH 697080 (12898), female, Utingu, 10 May; AMNH 697081 (13210), female, Utingu, 23 May. See below for a discussion of the complicated nomenclature of the Australian forms of P. buceroides.

Invariants of motion with stochastic resetting and space-time coupled returns

description: Motion under stochastic resetting serves to model a myriad of processes in physics and beyond, but in most cases studied to date resetting to the origin was assumed to take zero time or a time decoupled from the spatial position at the resetting moment. However, in our world, getting from one place to another always takes time and places that are further away take more time to be reached. We thus set off to extend the theory of stochastic resetting such that it would account for this inherent spatio-temporal coupling. We consider a particle that starts at the origin and follows a certain law of stochastic motion until it is interrupted at some random time. The particle then returns to the origin via a prescribed protocol. We study this model and surprisingly discover that the shape of the steady-state distribution which governs the stochastic motion phase does not depend on the return protocol. This shape invariance then gives rise to a simple, and generic, recipe for the computation of the full steady-state distribution. Several case studies are analyzed and a class of processes whose steady-state is completely invariant with respect to the speed of return is highlighted. For processes in this class we recover the same steady-state obtained for resetting with instantaneous returns---irrespective of whether the actual return speed is high or low. Our work significantly extends previous results on motion with stochastic resetting and is expected to find various applications in statistical, chemical, and biological physics.

Consequences of the US-China Trade War on the US Agriculture Industry: Evidence of Intra-industry Fragmentation
Creators: name: Kim, Gaegoung
Publisher: name: University of Chicago
Year: 2021

description: The majority of existing literature in trade politics finds support for the firm centric model in the manufacturing sector. Therefore, less is known about how preferences for trade policy are formed in other sectors of the economy, especially the agricultural sector. Using Political Action Committee (PAC) contribution data, this paper looks at how party preferences of US agricultural interest groups change before and after the onset of the US-China trade war. The two main findings of this paper are as follows: 1) PACs prior to the outbreak of the US-China trade war in 2016 were fairly unified in their political preferences with most donations going to the Republican party but from 2018 to 2020, preferences become highly variegated; 2) more profitable, exporting farms were more likely to shift their support to the Democratic party, while the less profitable, import-competing farms were more likely to continue supporting the Republican party. These findings are suggestive of two important facts. First, agricultural interest groups punish parties for implementing trade policies that harm their industry by giving less contributions. Second, the firm centric model holds in the US agriculture sector but only under certain circumstances where great harm has been inflicted on the agribusinesses.

description: High-resolution ARPES studies in cuprates have detected low-energy changes in the dispersion and absorption of quasi-particles at low temperatures, in particular, in the superconducting state. Based on a new 1/N expansion of the t-J-Holstein model, which includes collective antiferromagnetic fluctuations already in leading order, we argue that the observed low-energy structures are mainly caused by phonons and not by spin fluctuations, at least, in the optimal and overdoped regime.

description: Cancer stem cells have been shown to be critical to the development of a variety of solid cancers. The precise interplay mechanisms between cancer stem cells and the rest of a tissue are still not elucidated. To shed light on the interactions between stem and non-stem cancer cell populations we develop a two-population mathematical model, which is suitable to describe tumorsphere growth. Both interspecific and intraspecific interactions, mediated by the microenvironment, are included. We show that there is a tipping point, characterized by a transcritical bifurcation, where a purely non-stem cell attractor is replaced by a new attractor that contains both stem and differentiated cancer cells. The model is then applied to describe the outcome of a recent experiment. This description reveals that, while the intraspecific interactions are inhibitory, the interspecific interactions stimulate growth. This can be understood in terms of stem cells needing differentiated cells to reinforce their niches, and phenotypic plasticity favoring the de-differentiation of differentiated cells into cancer stem cells. We posit that this is a consequence of the deregulation of the quorum sensing that maintains homeostasis in healthy tissues.

 Philemon argenticeps kempi Mathews, 1912d: 101 (Cape York, Queensland).
 Now Philemon agenticeps kempi Mathews, 1912. See Salomonsen, 1967: 410, Schodde and Mason, 1999: 291, Christidis and Boles, 2008: 185–191, and Higgins et al., 2008: 682.
 HOLOTYPE: AMNH 697015, female?, collected at Utingu, Cape York, Queensland, Australia, on 8 June 1912, by Robin Kemp (no. 1001). From the Mathews Collection (no. 13208) via the Rothschild Collection.
 COMMENTS: Mathews cited his catalog number of the holotype in the original description; it bears Kemp’s original label and Mathews and Rothschild type labels. Mathews (1912d: 101) gave the range of kempi as ‘‘ Cape York.’’ Of all of the specimens of this form that Kemp collected on Cape York, the holotype is the only one cataloged by Mathews before the name was published on 18 September 1912. He had two additional specimens, collected on CapeYork by McLennan early enough, but I did not find them in Mathews’ catalog and do not know when they came into his possession: AMNH 697005, male, Jardine River, 12 April 1911; AMNH 697018, male, Cape York, 9 December 1910.
Utingu was a coconut plantation opposite Possession Island (Jack, 1921: 342), 10.43S, 142.24E (USBGN, 1957).

description: The paper is concerned with the existence and multiplicity of positive solutions of the nonhomogeneous Choquard equation over an annular type bounded domain. Precisely, we consider the following equation \[ -\De u = \left(\int_{\Om}\frac{|u(y)|^{2^*_μ}}{|x-y|^μ}dy\right)|u|^{2^*_μ-2}u+f \; \text{in}\; \Om,\quad u = 0 \; \text{ on } \pa \Om , \] where $\Om$ is a smooth bounded annular domain in $\mathbb{R}^N( N\geq 3)$, $2^*_μ=\frac{2N-μ}{N-2}$, $f \in L^{\infty}(\Om)$ and $f \geq 0$. We prove the existence of four positive solutions of the above problem using the Lusternik-Schnirelmann theory and varitaional methods, when the inner hole of the annulus is sufficiently small.

description: Vertically stacked and coupled InAs/GaAs self-assembled quantum dots (SADs) are predicted to exhibit a strong non-parabolic dependence of the interband transition energy on the electric field, which is not encountered in single SAD structures nor in other types of quantum structures. Our study based on an eight-band strain-dependent ${\bf k}\cdot{\bf p}$ Hamiltonian indicates that this anomalous quantum confined Stark effect is caused by the three-dimensional strain field distribution which influences drastically the hole states in the stacked SAD structures.

Using a combination of quasar spectra from HST/COS and from Keck/HIRES or VLT/UVES we measure column densities of, or determine limits on, CGM absorption lines. We then use a Monte-Carlo Markov chain approach with Cloudy to estimate the metallicity of cool (T$\sim$$10^4$K) CGM gas. We also use HST images to determine host galaxy inclination and quasar--galaxy azimuthal angles. Our sample spans a HI column density range of $13.8$ cm s$^{-1}

description: We propose a method of generating a vortex ring in a Bose-Einstein condensate by means of electromagnetically-induced atomic transitions. Some remnant population of atoms in a second internal state remains within the toroidal trap formed by the mean field repulsion of the vortex ring. This population can be removed, or it can be made to flow around the torus (i.e. within the vortex ring). If this flow has unit topological winding number, the entire structure formed by the two condensates is an example of a three-dimensional skyrmion texture.

Phase space veto method for next-to-leading order event generators in hadronic collisions
Creators: name: Dobbs, Matt
Publisher: name: arXiv
Year: 2001
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: A method for organizing next-to-leading order QCD calculations using a veto which enforces the cancellations between virtual and real emission diagrams is applied to hadronic collisions. The method employs phase space slicing with the slicing parameter determined dynamically event-by-event. It allows for the generation of unweighted events and can be consistently merged with a parton shower. The end product is more intuitive for the end user, as it is probabilistic, and can be easily interfaced to general purpose showering and hadronization programs to obtain a complete event description suitable for experimental analyses. As an example an event generator for the process pp --> Z + X at NLO is presented and interfaced consistently to the PYTHIA shower and hadronization package.

 Philemon argenticeps melvillensis Mathews, 1912b: 51 (Melville Island, Northern Territory).
 Now Philemon argenticeps argenticeps (Gould, 1840). See Salomonsen, 1967: 411, Schodde and Mason, 1999: 291, Christidis and Boles, 2008: 185–191, and Higgins et al., 2008: 682.
 HOLOTYPE: AMNH 696989, female, collected at Coopers Creek, Apsley Strait, Melville Island, Northern Territory, Australia, on 16 October 1911, by J.P. Rogers (no. 2195). From the Mathews Collection (no. 10757) via the Rothschild Collection.
 COMMENTS: Mathews cited his catalog number of the holotype in the original description and gave the range as ‘‘ Melville Island. ’’ The holotype bears Rogers’ original label and Mathews and Rothschild type labels. When this form was named, Mathews (1912b: 26) had received only two shipments of specimens from Melville Island, all collected in 1911. Paratypes are: males, AMNH 696983 (Mathews no. 10762), 29 September; AMNH 696984 (11547), 21 November; AMNH 696985 (11546), 16 November; females, AMNH 696986 (11548), 10 November; AMNH 696987 (11545), 29 November; AMNH 696988 (10756), 30 October; AMNH 696990 (10761), 1 October. An additional specimen, not in AMNH, was cataloged by Mathews as no. 11549, male, 25 November 1911 and, if found, is also a paratype.
Hart and Pilling (1964: 101) gave the location of Coopers Camp as directly across Apsley Strait from the Bathurst Island Mission Station, 11.45S, 130.41E (Times Atlas).

‘Not One but Many Silences’: The Functions of Silence in Foucauldian Discourse

description: From a broad consideration of discourse, a general set of questions emerges: Who is speaking and what are they saying? Who is not speaking and what are they not saying? What is the significance of each in either case? Here I take up a line of inquiry corresponding to the second part of this formulation regarding the lack of speakers and speech. My chosen path into this field of thought is through the writing of Michel Foucault—an especially convenient figure due to the capaciousness of his understanding of discourse. Much work on Foucault and language is focused on questions of discourse in its positivity, i.e. what discourse is, how it is formed, and what its potential power-effects are. However, there is also a corresponding set of ideas concerning a lack of discourse—i.e. silence—and much can be meaningfully said about these ideas in Foucault’s writing. Given these assertions, this thesis seeks to answer the following question: what is the function of silence in Foucault’s understanding of discourse?
