Bernoulli potential in type-I and weak type-II supercoductors: II. Surface dipole
P. Lipavsky, K. Morawetz, J. Kolacek +3
The Budd-Vannimenus theorem is modified to apply to superconductors in the Meissner state. The obtained identity links the surface value of the electrostatic potential to the densi…
Bernoulli potential in type-I and weak type-II superconductors: I. Surface charge
P. Lipavsky, K. Morawetz, J. Kolacek +3
The electrostatic potential close to the surface of superconductors in the Meissner state is discussed. We show that beside the Bernoulli potential, the quasiparticle screening, an…
Two Coupled Harmonic Oscillators on Non-commutative Plane
Ahmed Jellal, El Hassan El Kinani, Michael Schreiber
We investigate a system of two coupled harmonic oscillators on the non-commutative plane \RR^2_θ by requiring that the spatial coordinates do not commute. We show that the system c…
Anisotropic Quantum Hall Matrix Model
Ahmed Jellal, Rudolf A. Roemer, Michael Schreiber
We consider the anisotropic effect in the quantum Hall systems by applying a confining potential that is not of parabolic type. This can be done by extending Susskind--Polychronako…
Stochastic unraveling of Redfield master equations and its application to electron transfer problems
Ivan Kondov, Ulrich Kleinekathoefer, Michael Schreiber
A method for stochastic unraveling of general time-local quantum master equations (QMEs) is proposed. The present kind of jump algorithm allows a numerically efficient treatment of…
Resonance peak in underdoped cuprates
A. Sherman, M. Schreiber
The magnetic susceptibility measured in neutron scattering experiments in underdoped YBaCuO is interpreted based on the self-consistent solution of the t-J model of…
