Synthetic-lattice enabled all-optical devices based on orbital angular momentum of light
Nature Communications, 2017 Design of all-optical devices rely on large numbers of optical elements and precise control makes this approach challenging. The authors demonstrate that optical devices such as quantum memory and optical filters can be realized using synthetic orbital ...

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.

Trapping effects in quantum atomic arrays
SciPost 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.

Resonance Scattering in Optical Lattices and Molecules: Interband versus Intraband Effects
, 2010 We study the low-energy two-body scattering in optical lattices with all higher-band effects included in an effective potential, using a renormalization group approach.

Advanced Engineering Materials, EarlyView.Trace additions of Sn and Sr combined with a two‐step aging treatment are shown to enhance the microstructure and performance of Al–Zr–Sc conductor alloys. Strength and electrical conductivity increase concurrently through accelerated precipitation of fine Al3(Sc, Zr) precipitates and improved dislocation resistance, offering a cost‐effective pathway ...

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.

Chiral emission induced by optical Zeeman effect in polariton micropillars
Physical 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.

Application of Raman and Photoluminescence Spectroscopy to MgO‐C Refractories
Advanced Engineering Materials, EarlyView.Visible to near infrared luminescence of MgO is studied on MgO‐C bricks and nominally pure MgO powder, with focus on two similar sharp high‐intensity signals, at 699 and 871 nm, each surrounded by symmetrical sidebands. The nature of these sidebands is investigated by temperature‐dependent spectroscopic measurements, confirming phonon involvement by ...
