Crystallization in mass-asymmetric electron-hole bilayers
We consider a \textit{mass-asymmetric} electron and hole bilayer. Electron
and hole Coulomb correlations and electron and hole quantum effects are treated
on first princles by path integral Monte Carlo methods. For a fixed layer
separation we vary the mass ratio of holes and electrons between 1 and 100
and analyze the structural changes in the system. While, for the chosen
density, the electrons are in a nearly homogeneous state, the hole arrangement
changes from homogeneous to localized, with increasing which is verified
for both, mesoscopic bilayers in a parabolic trap and for a macroscopic system.Comment: 10 pages, latex (styles files included
Advancing numerics for the Casimir effect to experimentally relevant aspect ratios
Within the scattering theoretical approach, the Casimir force is obtained
numerically by an evaluation of the round trip of an electromagnetic wave
between the objects involved. Recently [Hartmann M et al. 2017, Phys. Rev.
Lett. 119 043901] it was shown that a symmetrization of the scattering operator
provides significant advantages for the numerical evaluation of the Casimir
force in the experimentally relevant sphere-plane geometry. Here, we discuss in
more detail how the symmetrization modifies the scattering matrix in the
multipole basis and how computational time is reduced. As an application, we
discuss how the Casimir force in the sphere-plane geometry deviates from the
proximity force approximation as a function of the geometric parameters.Comment: 9 pages, 8 figure
