The impact of nitrogen doping on the linear and nonlinear terahertz response of graphene
Roozbeh Anvari, Eugene Zaremba, Marc M. Dignam
It is well known that impurities play a central role in the linear and nonlinear response of graphene at optical and terahertz frequencies. In this work, we calculate the bands and…
Collective excitations of a harmonically trapped, two-dimensional, spin-polarized dipolar Fermi gas in the hydrodynamic regime
B. P. van Zyl, E. Zaremba, J. Towers
The collective excitations of a zero-temperature, spin-polarized, harmonically trapped, two-dimensional dipolar Fermi gas are examined within the Thomas-Fermi von Weizsäcker hydrod…
Probing the optical conductivity of trapped charge-neutral quantum gases
Zhigang Wu, Edward Taylor, Eugene Zaremba
We study a harmonically confined atomic gas which is subjected to an additional external potential such as an optical lattice. Using a linear response formulation, we determine the…
A nonlocal kinetic energy functional for an inhomogeneous two-dimensional Fermi gas
B. P. van Zyl, A. Farrell, E. Zaremba +3
The average-density approximation is used to construct a nonlocal kinetic energy functional for an inhomogeneous two-dimensional Fermi gas. This functional is then used to formulat…
Mean-field yrast spectrum of a two-component Bose gas in ring geometry: persistent currents at higher angular momentum
Zhigang Wu, Eugene Zaremba
We use analytic soliton solutions of a two-component Bose gas in ring geometry to analyze the mean-field yrast spectrum of the system. We find that the spectrum exhibits a surprisi…
Thomas-Fermi von Weizsäcker theory for a harmonically trapped, two-dimensional, spin-polarized dipolar Fermi gas
Brandon P. van Zyl, E. Zaremba, P. Pisarski
We systematically develop a density functional description for the equilibrium properties of a two-dimensional, harmonically trapped, spin-polarized dipolar Fermi gas based on the…
