Exact dynamics and bound states of a cavity coupled to a two-dimensional reservoir
Heng-Na Xiong, Da-Wei Ye, Yang Yang +4
We demonstrate a robust scheme for quantum information storage based on bound states in a two-dimensional coupled-cavity array. When a target cavity is tuned to resonance with the…
Maximal quantum Fisher information for general su(2) parametrization processes
Xiao-Xing Jing, Jing Liu, Heng-Na Xiong +1
Quantum Fisher information is a key concept in the field of quantum metrology, which aims to enhance the parameter accuracy by using quantum resources. In this paper, utilizing a r…
Fidelity susceptibility and quantum Fisher information for density operators with arbitrary ranks
Jing Liu, Heng-Na Xiong, Fei Song +1
Taking into account the density matrices with non-full ranks, we show that the fidelity susceptibility is determined by the support of the density matrix. Combining with the corres…
Reply to the Comment on "General Non-Markovian Dynamics of Open Quantum System"
Wei-Min Zhang, Ping-Yuan Lo, Heng-Na Xiong +2
This is the reply to the 2nd version of the comment, [arXiv.1312.5286v2], by McCutcheon {\it et al.} on our paper [PRL 109, 170402 (2012)]. Our letter presents three examples. For…
Breakdown of Bose-Einstein distribution in photonic crystals
Ping-Yuan Lo, Heng-Na Xiong, Wei-Min Zhang
In the last two decades, considerable advances have been made in the investigation of nano-photonics in photonic crystals. Previous theoretical investigations of photon dynamics we…
Non-Markovian Dynamics Impact on the Foundations of Statistical Mechanics
Heng-Na Xiong, Ping-Yuan Lo, Wei-Min Zhang +2
The foundations of statistical mechanics, namely how equilibrium hypothesis emerges microscopically from quantum theory, is explored through investigating the environment-induced q…
