Bose-Glass Phases of Ultracold Atoms due to Cavity Backaction Hessam Habibian,
... Bragg diffraction is a manifestation of the wave properties of light and provides a criterion for the existence of long-range order in the scattering medium [1]. Bragg diffraction of light by atoms in optical lattices was measured for various geometries and settings, from gratings of laser-cooled at ...

Feynman-Kac formula for L´evy processes and semiclassical (Euclidean) momentum representation
... instead of (1.7) with initial condition g(·) ∈ S(R). Finally we will study the limiting behavior of (1.8) as ~ approaches 0. Usually there are two different methods to derive a Feynman-Kac type formula: • martingale methods combined with the Itô formula (see for example Section 5.7 of [14] and Sect ...

The origins of interventionism can be traced back to the mid 20th century, more precisely, to Peter Bergmann and Joel Lebowitz’s paper ‘New Approach to Nonequilibrium Processes’ (1955) and to Reichenbach’s book The Direction of Time (1956). Also the model that J.M. Blatt put forward a few years late ...

Since spin gradient thermometry does not depend on the number of atoms per lattice site n, we perform measurements at a range of n values between 1 and 4. The trapping ...
