Superadiabatic and Speed Limited Quantum Driving of Bose-Einstein Condensates in Optical Lattices
, 2012 We implement optimal control schemes that approach the quantum speed limit as well as superadiabatic driving, achieving nearly perfect fidelity for a two-level quantum system realized with BECs in optical ...

Advanced Engineering Materials, EarlyView.A combined experimental–computational framework identifies energy‐dependent laser absorptivity for NiTi in laser powder‐bed fusion, applicable to conduction and transition modes. Single‐track experiments and thermofluid smoothed particle hydrodynamics simulations are coupled through inverse analysis of melt pool geometry.

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.

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.

Vortex solitons in moiré optical lattices
Optics Letters, 2023 We show that optical moiré lattices enable the existence of vortex solitons of different types in self-focusing Kerr media. We address the properties of such states both in lattices having commensurate and incommensurate geometries (i.e., constructed with Pythagorean and non-Pythagorean twist angles, respectively), in the different regimes that occur ...
