Three-tangle for mixtures of generalized GHZ and generalized W states
Christopher Eltschka, Andreas Osterloh, Jens Siewert +1
We give a complete solution for the three-tangle of mixed three-qubit states composed of a generalized GHZ state, a|000>+b|111>, and a generalized W state, c|001>+d|010>+f|100>. Us…
Tangles of superpositions and the convex-roof extension
Andreas Osterloh, Jens Siewert, Armin Uhlmann
We discuss aspects of the convex-roof extension of multipartite entanglement measures, that is, $SL(2,\CC)$ invariant tangles. We highlight two key concepts that contain valuable i…
Generalized plasma-like permittivity and thermal Casimir force between real metals
B. Geyer, G. L. Klimchitskaya, V. M. Mostepanenko
The physical reasons why the Drude dielectric function is not compatible with the Lifshitz formula, as opposed to the generalized plasma-like permittivity, are presented. Essential…
Thermal correction to the Casimir force, radiative heat transfer, and an experiment
V. B. Bezerra, G. Bimonte, G. L. Klimchitskaya +2
The low-temperature asymptotic expressions for the Casimir interaction between two real metals described by Leontovich surface impedance are obtained in the framework of thermal qu…
Pulsating Casimir force
G. L. Klimchitskaya, U. Mohideen, V. M. Mostepanenko
Based on the Lifshitz theory we show that the illumination of one (Si) plate in the three-layer systems Au--ethanol--Si, Si--ethanol--Si and -AlO--ethanol--Si with l…
Analytic approach to the thermal Casimir force between metal and dielectric
B. Geyer, G. L. Klimchitskaya, V. M. Mostepanenko
The analytic asymptotic expressions for the Casimir free energy, pressure and entropy at low temperature in the configuration of one metal and one dielectric plate are obtained. Fo…
