The matter beyond the ring: the recent evolution of SN 1987A observed by the Hubble Space Telescope

J. Larsson, C. Fransson, D. Alp +14

The nearby SN 1987A offers a spatially resolved view of the evolution of a young supernova remnant. Here we precent recent Hubble Space Telescope imaging observations of SN 1987A,…

Quadrupolar interactions between acceptor pairs in p-doped semiconductors

Adam C. Durst, Genesis Yang-Mejia, R. N. Bhatt

We consider the interaction between acceptor pairs in doped semiconductors in the limit of large inter-acceptor separation relevant for low doping densities. Modeling individual ac…

Nodeless superconducting gap in the candidate topological superconductor Sn $_{1 - x}$ In $_{x}$ Te for x = 0.7

M. P. Smylie, Kaya Kobayashi, T. Takahashi +4

High-pressure synthesis techniques have allowed for the growth of Sn $_{1 - x}$ In $_{x}$ Te samples beyond the ambient In-saturation limit of $x$ = 0.5 (T $_{c} \sim$ 4.5 K). In this study,…

A $6$ -chromatic two-distance graph in the plane

Geoffrey Exoo, Dan Ismailescu

We prove that if one colors each point of the Euclidean plane with one of five colors, then there exist two points of the same color that are either distance $1$ or distance $2$ ap…

Regularized deep learning with nonconvex penalties

Sujit Vettam, Majnu John

Regularization methods are often employed in deep learning neural networks (DNNs) to prevent overfitting. For penalty based DNN regularization methods, convex penalties are typical…

Magnetic and superconducting anisotropy in Ni-doped RbEuFe $_{4}$ As $_{4}$ single crystals

K. Willa, M. P. Smylie, Y. Simsek +5

We investigate the effect of Ni doping on the Fe-site in single crystals of the magnetic superconductor RbEuFe $_{4}$ As $_{4}$ for doping concentrations of up to 4%. A clear suppression…

The X-ray-Resolved Supernova Remnant S8 in the Dwarf Irregular Galaxy IC 1613

Eric M. Schlegel, Thomas G. Pannuti, T. Lozinskaya +2

We conducted an observation of the nearby irregular galaxy IC 1613 with the Chandra X-ray Observatory using the S3 chip of the ACIS with an effective exposure time of 49.9 ksec. Th…

Melting of vortex lattice in magnetic superconductor $Rb Eu Fe_{4} As_{4}$

A. E. Koshelev, K. Willa, R. Willa +6

The iron-based superconductors are characterized by strong fluctuations due to high transition temperatures and small coherence lengths. We investigate fluctuation behavior in the…

Anisotropic upper critical field of pristine and proton-irradiated single crystals of the magnetically ordered superconductor RbEuFe $_{4}$ As $_{4}$

M. P. Smylie, A. E. Koshelev, K. Willa +12

We present a study of the upper critical field, H $_{c 2}$ , of pristine and proton-irradiated RbEuFe $_{4}$ As $_{4}$ crystals in pulsed magnetic fields of up to 65 T. The data for H $_{c 2}$ …

The large $N$ limit of OPEs in symmetric orbifold CFTs with $N = (4, 4)$ supersymmetry

Thomas de Beer, Benjamin A. Burrington, Ian T. Jardine +1

We explore the OPE of certain twist operators in symmetric product ( $S_{N}$ ) orbifold CFTs, extending our previous work arXiv:1804.01562 to the case of $N = (4, 4)$ supersymme…

Nonlocal fermions and the entropy volume law

G. C. Levine

To produce a fermionic model exhibiting an entanglement entropy volume law, we propose a particular version of nonlocality in which the energy-momentum dispersion relation is effec…
