An ALMA Disk Mass for the Candidate Protoplanetary Companion to FW Tau
Adam L. Kraus, Sean M. Andrews, Brendan P. Bowler +5
We present ALMA observations of the FW Tau system, a close binary pair of M5 stars with a wide-orbit (300 AU projected separation) substellar companion. The companion is extremely…
Time-resolved spectroscopy in time dependent density functional theory: An exact condition
Johanna I. Fuks, Kai Luo, Ernesto D. Sandoval +1
A fundamental property of a quantum system driven by an external field is that when the field is turned off the positions of its response frequencies are independent of the time at…
Electromagnetic Wave Transmission Through a Subwavelength Nano-hole in a Two-dimensional Plasmonic Layer
Norman J. M. Horing, Desire Miessein, Godfrey Gumbs
An integral equation is formulated to describe electromagnetic wave transmission through a sub-wavelength nano-hole in a thin plasmonic sheet in terms of the dyadic Green's functio…
Surface Plasmon Instability Leading to Emission of Radiation
Godfrey Gumbs, Andrii Iurov, Danhong Huang +1
We propose a new energy conversion approach from a dc electric field to a terahertz wave based on hybrid semiconductors by combining two-dimensional (2D) crystalline layers and a t…
An Unstable Change of Rings for Morava E-Theory
Robert Thompson
The Bousfield-Kan (or unstable Adams) spectral sequence can be constructed for various homology theories such as Brown-Peterson homology theory BP, Johnson-Wilson theory , or…
SpeX Spectroscopy of Unresolved Very Low Mass Binaries. II. Identification of Fourteen Candidate Binaries with Late-M/Early-L and T Dwarf Components
Daniella C. Bardalez Gagliuffi, Adam J. Burgasser, Christopher R. Gelino +7
Multiplicity is a key statistic for understanding the formation of very low mass (VLM) stars and brown dwarfs. Currently, the separation distribution of VLM binaries remains poorly…
UCAC4 Nearby Star Survey: A Search for Our Stellar Neighbors
Charlie Finch, Norbert Zacharias, John Subasavage +2
We use data from the U.S. Naval Observatory fourth CCD Astrograph Catalog (UCAC4) in combination with photometry from the AAVSO Photometric All-Sky Survey (APASS) and Two Micron Al…
Stallings graphs for quasi-convex subgroups
Olga Kharlampovich, Alexei Miasnikov, Pascal Weil
We show that one can define and effectively compute Stallings graphs for quasi-convex subgroups of automatic groups (\textit{e.g.} hyperbolic groups or right-angled Artin groups).…
The Solar Neighborhood XXXV: Distances to 1404 M Dwarf Systems Within 25 pc in the Southern Sky
Jennifer G. Winters, Todd J. Henry, John C. Lurie +11
We present trigonometric, photometric, and photographic distances to 1748 southern (0) M dwarf systems with 0\farcs18 yr, of which 1404 are believed to…
Controlling quantum-dot light absorption and emission by a surface-plasmon field
Danhong Huang, Michelle Easter, Godfrey Gumbs +4
The possibility for controlling the probe-field optical gain and absorption switching and photon conversion by a surface-plasmon-polariton near field is explored for a quantum dot…
Two Notes on Grover's Search: Programming and Discriminating
Daniel Reitzner, Mario Ziman
In this work we address two questions concerning Grover's algorithm. In the first we give an answer to the question how to employ Grover's algorithm for actual search over database…
The exact forces on classical nuclei in non-adiabatic charge transfer
Federica Agostini, Ali Abedi, Yasumitsu Suzuki +3
The decomposition of electronic and nuclear motion presented in~[A. Abedi, N. T. Maitra, and E. K. U. Gross, Phys. Rev. Lett. 105, 123002 (2010)] yields a time-dependent potential…
Resonant Scattering of Surface Plasmon Polaritons by Dressed Quantum Dots
Danhong Huang, Michelle Easter, Godfrey Gumbs +4
The resonant scattering of surface plasmon-polariton waves by embedded semiconductor quantum dots above the dielectric/metal interface is explored in the strong-coupling regime. In…
Plasmons in a Superlattice of Fullerenes or Metallic Shells
Antonios Balassis, Godfrey Gumbs
A theory for the collective plasma excitations in a linear periodic array of spherical two-dimensional electron gases (S2DEGs) is presented. This is a simple model for an ultra thi…
Combined Effect of Stacking and Magnetic Field on Plasmon Excitations in Bilayer Graphene
Jhao-Ying Wu, Godfrey Gumbs, Ming-Fa Lin
The electronic excitations of bilayer graphene (BLG) under a magnetic field are investigated with the use of the Peierls tight-binding model in conjunction with random-phase approx…
Revealing Hofstadter Spectrum for Graphene in a Periodic Potential
Godfrey Gumbs, Andrii Iurov, Danhong Huang +1
We calculate the energy bands for graphene monolayers when electrons move through a periodic electrostatic potential in the presence of a uniform perpendicular magnetic field. We c…
The Coolest Isolated Brown Dwarf Candidate Member of TWA
Jonathan Gagné, Jacqueline K. Faherty, Kelle Cruz +4
We present two new late-type brown dwarf candidate members of the TW Hydrae association (TWA) : 2MASS J12074836-3900043 and 2MASS J12474428-3816464, which were found as part of the…
Modeling Anisotropic Plasmon Excitations in Self-Assembled Fullerenes
Andrii Iurov, Godfrey Gumbs, Bo Gao +1
The plasmon excitations in Coulomb-coupled spherical two-dimensional electron gases (S2DEGs) reveal an interesting dependence on the displacement vector between the centers of the…
Challenging Adiabatic Time-dependent Density Functional Theory with a Hubbard Dimer: The Case of Time-Resolved Long-Range Charge Transfer
Johanna I. Fuks, Neepa T. Maitra
We explore an asymmetric two-fermion Hubbard dimer to test the accuracy of the adiabatic approximation of time-dependent density functional theory in modelling time-resolved charge…
Accretion onto Planetary Mass Companions of Low-Mass Young Stars
Yifan Zhou, Gregory J. Herczeg, Adam L. Kraus +2
Measurements of accretion rates onto planetary mass objects may distinguish between different planet formation mechanisms, which predict different accretion histories. In this Lett…
