Coherent transport of neutral atoms in spin-dependent optical lattice potentials
, 2003 We demonstrate the controlled coherent transport and splitting of atomic wave packets in spin-dependent optical lattice potentials. Such experiments open intriguing possibilities for quantum state engineering of many body states.

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.

Reflectionless and invisible potentials in photonic lattices
, 2017 An arbitrarily-shaped optical potential on a discrete photonic lattice, which transversely drifts at a speed larger than the maximum one allowed by the light cone of the lattice band, becomes reflectionless.

Advanced Engineering Materials, EarlyView.Curvature‐tuned auxetic lattices are designed, fabricated, and mechanically characterized to reveal how geometric curvature governs stretchability, stress redistribution, and Poisson's ratio evolution. Photoelastic experiments visualize stress pathways, while hyperelastic simulations quantify deformation mechanics.

Spin–orbit modulated optical properties in Lieb-to-kagome lattices
Results in PhysicsWe investigate the optical conductivity of two-dimensional flat-band systems undergoing a transition from Lieb to kagome lattice geometries. Using a generalized tight-binding Hamiltonian with intrinsic spin–orbit coupling (ISOC), we compute both the real

Simulation of non-Abelian lattice gauge fields with a single component gas
, 2014 We show that non-Abelian lattice gauge fields can be simulated with a single component ultra-cold atomic gas in an optical lattice potential. An optical lattice can be viewed as a Bravais lattice with a $N$-point basis.

Advanced Engineering Materials, EarlyView.Microstructural evolution and hardness optimization along the cross‐section of friction stir welded AA6061/AlSi10MgMn joints, for electric vehicle battery housings, were investigated. Postweld aging between 170°C and 220°C enhances hardness uniformity within the nugget zone.

Cancellation of collisional frequency shifts in optical lattice clocks with Rabi spectroscopy
New Journal of Physics, 2016 We analyze both the s- and p -wave collision induced frequency shifts and propose an over- π pulse scheme to cancel the shifts in optical lattice clocks interrogated by a Rabi pulse.

Optical lattices with micromechanical mirrors [PDF]
Physical Review A, 2010 We investigate a setup where a cloud of atoms is trapped in an optical lattice potential of a standing wave laser field which is created by retro-reflection on a micro-membrane. The membrane vibrations itself realize a quantum mechanical degree of freedom.

Advanced Engineering Materials, EarlyView.In this experimental study, the mechanical properties of additively manufactured Ti‐6Al‐4V lattice structures of different geometries are characterized using compression, four point bending and fatigue testing. While TPMS designs show superior fatigue resistance, SplitP and Honeycomb lattice structures combine high stiffness and strength. The resulting
