A Method to Modify RMT using Short-Time Behavior in Chaotic Systems

A. Matthew Smith, Lev Kaplan

We discuss a modification to Random Matrix Theory eigenstate statistics, that systematically takes into account the non-universal short-time behavior of chaotic systems. The method…

Exchange-Correlation Energy Functional Based on the Airy-Gas Reference System

Lucian A. Constantin, Adrienn Ruzsinszky, John P. Perdew

In recent work, generalized gradient approximations (GGA's) have been constructed from the energy density of the Airy gas for exchange but not for correlation. We report the random…

Workhorse Semilocal Density Functional for Condensed Matter Physics and Quantum Chemistry

John P. Perdew, Adrienn Ruzsinszky, Gabor I. Csonka +2

Semilocal density functionals for the exchange-correlation energy are needed for large electronic systems. The Tao-Perdew-Staroverov-Scuseria (TPSS) meta-generalized gradient appro…

Monge-Ampere foliations for degenerate solutions

Morris Kalka, Giorgio Patrizio

We study the problem of the existence and the holomorphicity of the Monge-Ampère foliation associated to a plurisubharmonic solutions of the complex homogeneous Monge-Ampère equati…

Spin Gap and Resonance at the Nesting Wavevector in Superconducting FeSe0.4Te0.6

Yiming Qiu, Wei Bao, Yang Zhao +9

Neutron scattering is used to probe magnetic excitations in FeSe_{0.4}Te_{0.6} (T_c=14 K). Low energy spin fluctuations are found with a characteristic wave vector th…

The p-adic valuations of sequences counting alternating sign matrices

Xinyu Sun, Victor H. Moll

The p-adic valuations of a sequence of integers T(n) counting alternating sign matrices is examined for p=2 and p=3. Symmetry properties of their graphs produce a new proof of the…
