Quantum phase transition in an array of coupled dissipative cavities
Ke Liu, Lei Tan, C. -H Lv +1
The features of superfluid-Mott insulator phase transition in the array of dissipative nonlinear cavities are analyzed. We show analytically that the coupling to the bath can be re…
Pauli equation for a charged spin particle on a curved surface in an electric and magnetic field
Yong-Long Wang, Long Du, Chang-Tan Xu +2
We derive the Pauli equation for a charged spin particle confined to move on a spatially curved surface in an electromagnetic field. Using the thin-layer quantization…
Curvature-induced bound states and coherent electron transport on the surface of a truncated cone
Long Du, Yong-Long Wang, Guo-Hua Liang +3
We study the curvature-induced bound states and the coherent transport properties for a particle constrained to move on a truncated cone-like surface. With longitudinal hard wall b…
Post-selected von Neumann measurement with Hermite-Gaussian and Laguerre-Gaussian pointer states
Yusuf Turek, Hirokazu Kobayashi, Tomotada Akutsu +2
Through the von Neumann interaction followed by post-selection, we can extract not only the eigenvalue of an observable of the measured system but also the weak value. In this post…
Uhrig Dynamical Control of a Three-Level System Via Non-Markovian Quantum State Diffusion
Wenchong Shu, Xinyu Zhao, Jun Jing +2
In this paper, we use the quantum state diffusion (QSD) equation to implement the Uhrig dynamical decoupling (UDD) to a three-level quantum system coupled to a non-Markovian reserv…
Phase-kicked control of counter-rotating interactions in the quantum Rabi model
Jin-Feng Huang, C. K. Law
We present an interaction scheme to control counter-rotating terms in the quantum Rabi model. We show that by applying a sequence of phase kicks to a two-level atom and a sin…
