Exact Maps in Density Functional Theory for Lattice Models
Tanja Dimitrov, Heiko Appel, Johanna I. Fuks +1
In the present work, we employ exact diagonalization for model systems on a real-space lattice to explicitly construct the exact density-to-potential and for the first time the exa…
Thermal smearing of the magneto-Kohn anomaly for Dirac materials and comparison with the two-dimensional electron liquid
Godfrey Gumbs, Antonios Balassis, Dipendra Dahal +1
We compute and compare the effects due to a uniform perpendicular magnetic field as well as temperature on the static polarization functions for monolayer graphene (MLG), associate…
Coherence as a resource in decision problems: The Deutsch-Jozsa algorithm and a variation
Mark Hillery
That superpositions of states can be useful for performing tasks in quantum systems has been known since the early days of quantum information, but only recently has quantitative t…
Plasmon dissipation in gapped-graphene open systems at finite temperature
Andrii Iurov, Godfrey Gumbs, Danhong Huang +1
Numerical and closed-form analytic expressions for plasmon dispersion relations and rates of dissipation are first obtained at finite-temperatures for free-standing gapped graphene…
Kepler Monitoring of an L Dwarf II. Clouds with Multiyear Lifetimes
John E. Gizis, Kyle G. Dettman, Adam J. Burgasser +7
We present Kepler, Spitzer Space Telescope, Gemini-North, MMT, and Kitt Peak observations of the L1 dwarf WISEP J190648.47+401106.8. We find that the Kepler optical light curve is…
Relations between coherence and path information
Emilio Bagan, Janos A. Bergou, Seth S. Cottrell +1
We find two relations between coherence and path-information in a multi-path interferometer. The first builds on earlier results for the two-path interferometer, which used minimum…
Environmental Effects on the Terahertz Surface Plasmons in Epitaxial Graphene
Godfrey Gumbs, Andrii Iurov, Jhao-Ying Wu +2
In this paper, we predict the existence of low-frequency nonlocal plasmon excitations at the vacuum-surface interface of a superlattice of graphene layers interacting with a th…
Fundamental Parameters and Spectral Energy Distributions of Young and Field Age Objects with Masses Spanning the Stellar to Planetary Regime
Joseph C. Filippazzo, Emily L. Rice, Jacqueline Faherty +3
We combine optical, near-infrared and mid-infrared spectra and photometry to construct expanded spectral energy distributions (SEDs) for 145 field age (\textgreater 500 Myr) and 53…
The Exact Potential Driving the Electron Dynamics in Enhanced Ionization
Elham Khosravi, Ali Abedi, Neepa T. Maitra
It was recently shown that the exact factorization of the electron-nuclear wavefunction allows the construction of a Schrödinger equation for the electronic system, in which the po…
Geodesically Complete Hyperbolic Structures
Ara Basmajian, Dragomir Saric
In the first part of this work we explore the geometry of infinite type surfaces and the relationship between its convex core and space of ends. In particular, we show that a geode…
The Brown Dwarf Kinematics Project (BDKP). IV. Radial Velocities of 85 Late-M and L dwarfs with MagE
Adam J. Burgasser, Sarah E. Logsdon, Jonathan Gagne +6
Radial velocity measurements are presented for 85 late M- and L-type very low mass stars and brown dwarfs obtained with the Magellan Echellette (MagE) spectrograph. Targets primari…
A Geometric Approach to Quantum State Separation
Emilio Bagan, Vadim Yerokhin, Andi Shehu +2
Probabilistic quantum state transformations can be characterized by the degree of state separation they provide. This, in turn, sets limits on the success rate of these transformat…
The BANYAN All-Sky Survey for Brown Dwarf Members of Young Moving Groups
Jonathan Gagné, David Lafrenière, René Doyon +9
We describe in this work the BASS survey for brown dwarfs in young moving groups of the solar neighborhood, and summarize the results that it generated. These include the discovery…
The effect of perpendicular electric field on Temperature-induced plasmon excitations for intrinsic silicene
Jhao-Ying Wu, Chiun-Yan Lin, Godfrey Gumbs +1
We use the tight-binding model and the random-phase approximation to investigate the intrinsic plasmon in silicene. At finite temperatures, an undamped plasmon is generated from th…
Probabilistically Perfect Cloning of Two Pure States: A Geometric Approach
Vadim Yerokhin, Andi Shehu, Edgar Feldman +2
We solve the long-standing problem of making n perfect clones from m copies of one of two known pure states with minimum failure probability in the general case where the known sta…
A Simple Method for Finding the Scattering Coefficients of Quantum Graphs
Seth S. Cottrell
Quantum walks are roughly analogous to classical random walks, and like classical walks they have been used to find new (quantum) algorithms. When studying the behavior of large gr…
A 3D Search for Companions to 12 Nearby M-Dwarfs
Cassy L. Davison, Russel J. White, Todd J. Henry +7
We present a carefully vetted equatorial ( 30 Decl.) sample of all known single (within 4'') mid M-dwarfs (M2.5V-M8.0V) extending out to 10 pc; their proximity and low…
Coulomb Excitations for a Short Linear Chain of Metallic Shells
Liubov Zhemchuzhna, Godfrey Gumbs, Andrii Iurov +2
A self-consistent-field theory is given for the electronic collective modes of a chain containing a finite number, , of Coulomb-coupled spherical two-dimensional electron gases…
