Photon blockade effect from synergistic optical parametric amplification and driving force in Kerr-medium single-mode cavity
Zhang Zhiqiang
This work investigates photon blockade control in a hybrid quantum system containing a Kerr-nonlinear cavity coupled to an optical parametric amplifier (OPA). The dynamics are gove…
Predicting band gaps and band-edge positions of oxide perovskites using DFT and machine learning
Wei Li, Zigeng Wang, Xia Xiao +4
Density functional theory within the local or semilocal density approximations (DFT-LDA/GGA) has become a workhorse in electronic structure theory of solids, being extremely fast a…
The cause of extremely long-lasting room-temperature persistent photoconductivity in SrTiO and related materials
Zhiqiang Zhang, Anderson Janotti
It has been recently revealed that strontium titanate (SrTiO) displays persistent photoconductivity with unique characteristics: it occurs at room temperature and lasts over a…
Band gap evolution in Ruddlesden-Popper phases
Wei Li, Shanyuan Niu, Boyang Zhao +3
We investigate the variation of the band gap across the Ruddlesden-Popper (RP) series (An+1BnX3n+1) in model chalcogenide, oxide, and halide materials to understand the factors inf…
Non-equilibrium phase transition in a spin-1 Dicke model
Zhang Zhiqiang, Chern Hui Lee, Ravi Kumar +4
We realize a spin-1 Dicke model using magnetic sub-levels of the lowest F=1 hyperfine level of Rb atoms confined to a high finesse cavity. We study this system under conditi…
