Haake-Lewenstein-Wilkens approach to spin-glasses revisited

Maciej Lewenstein, David Cirauqui, Miguel Angel Garcia-March +5

We revisit the Haake-Lewenstein-Wilkens (HLW) approach to Edwards-Anderson (EA) model of Ising spin glass [Phys. Rev. Lett. 55, 2606 (1985)]. This approach consists in evaluation a…

Gravitational properties of light - The emission of counter-propagating laser pulses from an atom

Dennis Rätzel, Martin Wilkens, Ralf Menzel

The gravitational field of a laser pulse, although not detectable at the moment, comes with a peculiar feature which continues to attract attention; cause and effect propagate with…

The effect of polarization entanglement in photon-photon scattering

Dennis Rätzel, Martin Wilkens, Ralf Menzel

It is found that the differential cross section of photon-photon scattering is a function of the degree of polarization entanglement of the two-photon state. A reduced, general exp…

Gravitational properties of light - The gravitational field of a laser pulse

Dennis Rätzel, Martin Wilkens, Ralf Menzel

The gravitational field of a laser pulse of finite lifetime, is investigated in the framework of linearized gravity. Although the effects are very small, they may be of fundamental…

The effect of entanglement in gravitational photon-photon scattering

Dennis Rätzel, Martin Wilkens, Ralf Menzel

The differential cross section for gravitational photon-photon scattering calculated in Perturbative Quantum Gravity is shown to depend on the degree of polarization entanglement o…

Ground-state properties of trapped Bose-Fermi mixtures: role of exchange-correlation

Alexander P. Albus, Fabrizio Illuminati, Martin Wilkens

We introduce Density Functional Theory for inhomogeneous Bose-Fermi mixtures, derive the associated Kohn-Sham equations, and determine the exchange-correlation energy in local dens…
