Bloch oscillations of cold atoms in optical lattices

, 2004
This work is devoted to Bloch oscillations (BO) of cold neutral atoms in optical lattices. After a general introduction to the phenomenon of BO and its realization in optical lattices, we study different extentions of this problem, which account for ...

Observation of exceptional points in reconfigurable non-Hermitian vector-field holographic lattices

Nature Communications, 2016
Non-Hermitian Hamiltonians have attracted significant attention because of the unconventional wave-dynamic effects they allow. Here, Hahn et al. report reconfigurable non-Hermitian photonic lattices that permit versatile control of real and imaginary sub-

Trace Nickel Activated Biphasic Core‐CuOii/Shell‐CuOi Secondary Microspheres Enable Room Temperature Parts‐Per‐Trillion‐Level NO2 Detection

Advanced Engineering Materials, EarlyView.
An idea of designing novel sensors is proposed by creating appropriate Schottky barriers and vacancies between isomorphous Core‐CuOii/ Shell‐CuOi secondary microspheres and enhancing catalytic and spill‐over effects, and electronegativity via spontaneous biphasic separation, self‐assembly, and trace‐Ni‐doping.

Quantum walk and Anderson localization of rotational excitations in disordered ensembles of polar molecules

New Journal of Physics, 2015
We consider the dynamics of rotational excitations placed on a single molecule in spatially disordered one-dimensional (1D), two-dimensional (2D) and three-dimensional (3D) ensembles of ultracold molecules trapped in optical lattices. The disorder arises
