Multiple Current Reversals Using Superimposed Driven Lattices

open access: yesApplied Sciences, 2020
We demonstrate that directed transport of particles in a two dimensional driven lattice can be dynamically reversed multiple times by superimposing additional spatially localized lattices on top of a background lattice.

Chiral emission induced by optical Zeeman effect in polariton micropillars

open access: yesPhysical Review Research, 2021
The low sensitivity of photons to external magnetic fields is one of the major challenges for the engineering of photonic lattices with broken time-reversal symmetry.

Trapping effects in quantum atomic arrays

open access: yesSciPost Physics Core, 2022
Quantum emitters, particularly atomic arrays with subwavelength lattice constant, have been proposed to be an ideal platform for studying the interplay between photons and electric dipoles.

Solitons in optical mesh lattices

open access: yes, 2013
We study nonlinear dynamics of light in a new class of optical lattices which are discretized in both the transverse and longitudinal directions. We show that such lattices admit different families of soliton solutions.

Low‐Angle Grain Boundaries and Re‐Segregation in Single‐Crystalline Ni‐Base Superalloys

open access: yesAdvanced Engineering Materials, EarlyView.
This work demonstrates that Re‐segregation at low‐angle grain boundaries (LAGBs) in Ni‐base superalloys is influenced by misorientation angle. Advanced microscopy and atom probe tomography reveal that higher misorientation angles increases Re‐segregation.

Cold bosons in optical lattices [PDF]

open access: yesLaser Physics, 2009
Basic properties of cold Bose atoms in optical lattices are reviewed. The main principles of correct self-consistent description of arbitrary systems with Bose-Einstein condensate are formulated. Theoretical methods for describing regular periodic lattices are presented. A special attention is paid to the discussion of Bose-atom properties in the frame

Large-amplitude superexchange of high-spin fermions in optical lattices

open access: yesNew Journal of Physics, 2013
We show that fermionic high-spin systems with spin-changing collisions allow one to monitor superexchange processes in optical superlattices with large amplitudes and strong spin fluctuations.
