Multiple Current Reversals Using Superimposed Driven Lattices
Applied 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.

Bloch oscillations in complex crystals with PT symmetry
, 2009 Bloch oscillations (BO) in complex lattices with PT symmetry are theoretically investigated with specific reference to optical BO in photonic lattices with gain/loss regions. Novel dynamical phenomena with no counterpart in ordinary lattices, such as non-

Optical conductivity with holographic lattices [PDF]
Journal of High Energy Physics, 2012 We add a gravitational background lattice to the simplest holographic model of matter at finite density and calculate the optical conductivity. With the lattice, the zero frequency delta function found in previous calculations (resulting from translation invariance) is broadened and the DC conductivity is finite.

Advanced Functional Materials, EarlyView.A lack of standard approaches for testing and reporting the performance of metal halide perovskites and organic semiconductor radiation detectors has resulted in inconsistent interpretation of performance parameters, impeding progress in the field. This Perspective recommends key metrics and experimental details, which are suggested for reporting in ...

Advanced Functional Materials, EarlyView.The separation of Helium gas from natural gas is challenging but highly important. MIL‐116(Ga), a “non‐porous” metal–organic framework is used as a molecular sieve to separate He from CH4. Druse‐like MIL‐116(Ga) particles are integrated into polysulfone mixed matrix membranes.

Time-dependent variational Monte Carlo study of the dynamic response of bosons in an optical lattice
SciPost Physics, 2022 We study the dynamics of a one-dimensional Bose gas at unit filling in both shallow and deep optical lattices and obtain the dynamic structure factor ${S(k,\omega)}$ by monitoring the linear response to a weak probe pulse. We introduce a new procedure,

Topological decomposition of hierarchical skyrmion lattices
Communications PhysicsThe decomposition of topological lattices is crucial for understanding their evolution and behavior in complex systems. Typically, decomposed substructures retain the primary lattice’s topology.

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