Coherent Phonons, Localization, and Slow Polaron Formation in Lead‐Free Gold Perovskite
Advanced Optical Materials, EarlyView.Using ultrafast optical and Raman spectroscopy with bandstructure calculations, coupled electronic and vibrational dynamics are explained in Cesium Gold Bromide, a promising lead‐free perovskite. Photoexcitation is strongly coupled to Au─Br stretching phonon modes. Lattice relaxation along these modes leads to a polaronic state.

Deterministic nonlinear phase gates induced by a single qubit
New Journal of Physics, 2018 We propose deterministic realizations of nonlinear phase gates by repeating a finite sequence of non-commuting Rabi interactions between a harmonic oscillator and only a single two-level ancillary qubit.

A Design Study of 100GHz Band Local Oscillator System by Using Yig Oscillator [PDF]
Journal of Astronomy and Space Sciences, 2003 In this paper, we make a design study for a local oscillator system of the 100 GHz band cosmic radio receiving system. We use the YIG oscillator with digital driver which is the main oscillator. This oscillator has a good frequency and phase stability at

Photochromic Molecules Enable Optical Control of Optomechanical Coupling in a Cavity
Advanced Optical Materials, EarlyView.An optomechanical system with optically‐tunable coupling is introduced, featuring a multilayered membrane with a photochromic molecule and NIR‐absorbing dye. Laser cooling of a membrane vibrational mode is evidenced, with a 60% improvement in efficiency achieved upon photoisomerization, as well as reversible control of photothermal forces.

Non-classical correlations beyond Bell’s inequality violation in qubit-pairs with an intrinsic noise
Results in Physics, 2019 In this paper, we analytically explore two qubits interacting with a coherent harmonic oscillator field under intrinsic noise. The interaction of the uncorrelated two qubits with a harmonic oscillator initially in the superposition of coherent states ...
