Quantum paraelastic two-dimensional materials
Tyler B. Bishop, Erin E. Farmer, Afsana Sharmin +3
We study the elastic energy landscape of two-dimensional tin oxide (SnO) monolayers and demonstrate a transition temperature of K using ab-initio molecular dynamic…
On the magnetoelastic and magnetoelectric couplings across the antiferromagnetic transition in multiferroic BiFeO3
Mariusz Lejman, Charles Paillard, Vincent Juvé +7
Clear anomalies in the lattice thermal expansion (deviation from linear variation) and elastic properties (softening of the sound velocity) at the antiferromagnetic-to-paramagnetic…
Curved Space, curved Time, and curved Space-Time in Schwarzschild geodetic geometry
Rafael T. Eufrasio, Nicholas A. Mecholsky, Lorenzo Resca
We investigate geodesic orbits and manifolds for metrics associated with Schwarzschild geometry, considering space and time curvatures separately. For `a-temporal' space, we solve…

Image Processing in Quantum Computers
Aditya Dendukuri, Khoa Luu
Quantum Image Processing (QIP)is an exciting new field showing a lot of promise as a powerful addition to the arsenal of Image Processing techniques. Representing image pixel by pi…
Emergence of intrinsic superconductivity below 1.178 K in the topologically non-trivial semimetal state of CaSn3
Y. L. Zhu, J. Hu, F. N. Womack +4
Topological materials which are also superconducting are of great current interest, since they may exhibit a non-trivial topologically-mediated superconducting phase. Although ther…
Magnetic Interactions in BiFeO: a First-Principles Study
Changsong Xu, Bin Xu, Bertrand Dupé +1
First-principles calculations, in combination with the four-state energy mapping method, are performed to extract the magnetic interaction parameters of multiferroic BiFeO. Suc…
Interplay between Kitaev interaction and single ion anisotropy in ferromagnetic CrI and CrGeTe monolayers
Changsong Xu, Junsheng Feng, Hongjun Xiang +1
Magnetic anisotropy is crucially important for the stabilization of two-dimensional (2D) magnetism, which is rare in nature but highly desirable in spintronics and for advancing fu…
Constraining the potential liquid water environment at Gale crater, Mars
Edgard G. Rivera-Valentín, Raina V. Gough, Vincent F. Chevrier +3
The Mars Science Laboratory (MSL) Rover Environmental Monitoring Station (REMS) has now made continuous in-situ meteorological measurements for several martian years at Gale crater…
Automatic Face Aging in Videos via Deep Reinforcement Learning
Chi Nhan Duong, Khoa Luu, Kha Gia Quach +4
This paper presents a novel approach to synthesize automatically age-progressed facial images in video sequences using Deep Reinforcement Learning. The proposed method models facia…
Injection current in ferroelectric group-IV monochalcogenide monolayers
Suman Raj Panday, Salvador Barraza-Lopez, Tonatiuh Rangel +1
We study the injection current response tensor (also known as circular photogalvanic effect or ballistic current) in ferrolectric monolayer GeS, GeSe, SnS, and SnSe. We find that t…
On-Chip Chiral Single-Photon Interface: Isolation and Unidirectional Emission
Lei Tang, Jiangshan Tang, Weidong Zhang +5
Chiral quantum systems have received intensive attention in fundamental physics and applications in quantum information processing including optical isolation and photon unidirecti…
On the Nature of the X-ray Emission from the Ultraluminous X-ray Source, M33 X-8: New Constraints from NuSTAR and XMM-Newton
Lacey A. West, Bret D. Lehmer, Daniel Wik +12
We present nearly simultaneous NuSTAR and XMM-Newton observations of the nearby (832 kpc) ultraluminous X-ray source (ULX) M33 X-8. M33 X-8 has a 0.3-10 keV luminosity of LX ~ 1.4…
Variability-selected low-luminosity active galactic nuclei candidates in the 7 Ms Chandra Deep Field-South
N. Ding, B. Luo, W. N. Brandt +13
In deep X-ray surveys, active galactic nuclei (AGNs) with a broad range of luminosities have been identified. However, cosmologically distant low-luminosity AGN (LLAGN, $L_{\mathrm…
Leveraging Product as an Activation Function in Deep Networks
Luke B. Godfrey, Michael S. Gashler
Product unit neural networks (PUNNs) are powerful representational models with a strong theoretical basis, but have proven to be difficult to train with gradient-based optimizers.…
Water splits to degrade two-dimensional group-IV monochalcogenides in nanoseconds
Salvador Barraza-Lopez, Thaneshwor P. Kaloni
