γ-Cycles In Arc-Colored Digraphs
Discussiones Mathematicae Graph Theory, 2016 We call a digraph D an m-colored digraph if the arcs of D are colored with m colors. A directed path (or a directed cycle) is called monochromatic if all of its arcs are colored alike.

An atom interferometer enabled by spontaneous decay [PDF]
, 2005 We investigate the question whether Michelson type interferometry is possible if the role of the beam splitter is played by a spontaneous process. This question arises from an inspection of trajectories of atoms bouncing inelastically from an evanescent ...

Localization of Matter Waves in 2D-Disordered Optical Potentials [PDF]
, 2005 We consider ultracold atoms in 2D-disordered optical potentials and calculate microscopic quantities characterizing matter wave quantum transport in the non-interacting regime.

Thermal limitation of far-field matter-wave interference [PDF]
, 2006 We assess the effect of the heat radiation emitted by mesoscopic particles on their ability to show interference in a double slit arrangement. The analysis is based on a stationary, phase-space based description of matter wave interference in the ...

Kernels by monochromatic paths and the color-class digraph
Discussiones Mathematicae Graph Theory, 2011 An m-coloured digraph is a digraph whose arcs are coloured with m colors. A directed path is monochromatic when its arcs are coloured alike. A set S ⊆ V (D) is a kernel by monochromatic paths whenever the two following conditions hold: 1. For any x, y ∈ S, x 6= y, there is no monochromatic directed path between them. 2.

Entanglement and Thouless times from coincidence measurements across disordered media
, 2011 We show that the entanglement of an initially frequency-entangled photon pair propagating through a disordered scattering medium can be read off in transmission from the coincidence counting rate.

Path-tracing Monte Carlo Library for 3D Radiative Transfer in Highly Resolved Cloudy Atmospheres [PDF]
, 2019 Interactions between clouds and radiation are at the root of many difficulties in numerically predicting future weather and climate and in retrieving the state of the atmosphere from remote sensing observations. The large range of issues related to these

On the spin-rotation-gravity coupling [PDF]
, 1998 The inertial and gravitational properties of intrinsic spin are discussed and some of the recent work in this area is briefly reviewed. The extension of relativistic wave equations to accelerated systems and gravitational fields is critically examined. A

Quantum Brownian motion in ratchet potentials
, 2002 We investigate the dynamics of quantum particles in a ratchet potential subject to an ac force field. We develop a perturbative approach for weak ratchet potentials and force fields.
