Patchy Forsterite Clouds in the Atmospheres of Two Highly Variable Exoplanet Analogs
Johanna M. Vos, Ben Burningham, Jacqueline K. Faherty +12
We present an atmospheric retrieval analysis of a pair of highly variable, Myr old, early-T type planetary-mass exoplanet analogs SIMP J01365662+0933473 and 2MASS J213926…
Dynamical optical conductivity for gapped materials with a curved "flat" band
Andrii Iurov, Liubov Zhemchuzhna, Godfrey Gumbs +1
We have calculated the dynamical optical conductivity for materials in the presence of a finite bandgap in their energy bandstructure. This is a special type of e…
Local behavior of the Eden model on graphs and tessellations of manifolds
Dongming Hua, Fedor Manin, Tahda Queer +1
The Eden Model in constructs a blob as follows: initially a single unit hypercube is infected, and each second a hypercube adjacent to the infected ones is selected…
Development of a Neural Network-Based Mathematical Operation Protocol for Embedded Hexadecimal Digits Using Neural Architecture Search (NAS)
Victor Robila, Kexin Pei, Junfeng Yang
It is beneficial to develop an efficient machine-learning based method for addition using embedded hexadecimal digits. Through a comparison between human-developed machine learning…
Examining the Rotation Period Distribution of the 40 Myr Tucana-Horologium Association with TESS
Mark Popinchalk, Jacqueline K. Faherty, Jason L. Curtis +6
The Tucana-Horologium Association (Tuc-Hor) is a 40 Myr old moving group in the southern sky. In this work, we measure the rotation periods of 313 Tuc-Hor objects with TESS light c…
Discovery of a Mid-L Dwarf Companion to the L 262-74 System
Léopold Gramaize, Adam C. Schneider, Federico Marocco +9
We present the discovery of CWISE J151044.74524923.5, a wide low-mass companion to the nearby (24.7 pc) system L 262-74, which was identified through the Backyard Worlds:…
Discrete outcome quantum sensor networks
Mark Hillery, Himanshu Gupta, Caitao Zhan
We model a quantum sensor network using techniques from quantum state discrimination. The interaction between a qubit detector and the environment is described by a unitary operato…
The Oceanus Moving Group: A New 500 Myr-Old Host for the Nearest Brown Dwarf
Jonathan Gagné, Leslie Moranta, Jacqueline K. Faherty +5
We report the discovery of the Oceanus moving group, a 500 Myr-old group with 50 members and candidate members at distances 2-50 pc from the Sun using an unsupervised clu…
The Astropy Project: Sustaining and Growing a Community-oriented Open-source Project and the Latest Major Release (v5.0) of the Core Package
The Astropy Collaboration, Adrian M. Price-Whelan, Pey Lian Lim +133
The Astropy Project supports and fosters the development of open-source and openly-developed Python packages that provide commonly needed functionality to the astronomical communit…
Models for the Cohomology of Certain Polyhedral Products
Martin Bendersky, Jelena Grbić
For a commutative ring with unit, we describe and study various differential graded -modules and -algebras which are models for the cohomology of…
wdwarfdate: A Python Package to Derive Bayesian Ages of White Dwarfs
Rocio Kiman, Siyi Xu, Jacqueline K. Faherty +5
White dwarfs have been successfully used as cosmochronometers in the literature, however their reach has been limited in comparison to their potential. We present wdwarfdate, a pub…
Developing a semiclassical Wentzel-Kramers-Brillouin theory for model
Kathy Blaise, Chinedu Ejiogu, Andrii Iurov +3
We have developed a complete semiclassical Wentzel-Kramers-Brillouin (WKB) theory for model which describes a wide class of existing pseudospin-1 Dirac cone mater…
Polarizability, plasmons, and screening in 1T-MoS with tilted Dirac bands
Antonios Balassis, Godfrey Gumbs, Oleksiy Roslyak
In the presence of an external vertical electric field and strain, it is evident that 1T-MoS exhibits tilted Dirac bands which are valley-spin-polarized. Additionall…
Plasmon damping rates in Coulomb-coupled two-dimensional layers in a heterostructure
Dipendra Dahal, Godfrey Gumbs, Andrii Iurov +1
The Coulomb excitations of charge density oscillation are calculated for a double-layer heterostructure. Specifically, we consider two-dimensional (2D) layers of silicene and graph…
Broadcast of a restricted set of qubit and qutrit states
Mark Hillery, János A. Bergou, Tzu-Chieh Wei +2
The no-cloning theorem forbids the distribution of an unknown state to more than one receiver. However, if the sender knows the state, and the state is chosen from a restricted set…
Characteristic function and operator approach to M-indeterminate probability densities
Patrick Loughlin, Leon Cohen
Based on a quantum mechanical approach, we investigate moment- (or M-) indeterminate probability densities by way of the characteristic function and self-adjoint operators. The app…
Glyme-based electrolytes: suitable solutions for next-generation lithium batteries
Daniele Di Lecce, Vittorio Marangon, Hun-Gi Jung +3
The concept of green in a battery involves the chemical nature of electrodes and electrolytes as well as the economic sustainability of the cell. Although these aspects are typical…
Finite-temperature plasmons, damping and collective behavior for model
Andrii Iurov, Liubov Zhemchuzhna, Godfrey Gumbs +3
We have conducted a thorough theoretical and numerical investigation of the electronic susceptibility, polarizability, plasmons, their damping rates, as well as the static screenin…
