Two Mode Photon Bunching Effect as Witness of Quantum Criticality in Circuit QED
Qing Ai, Ying-Dan Wang, Guilu Long +1
We suggest a scheme to probe critical phenomena at a quantum phase transition (QPT) using the quantum correlation of two photonic modes simultaneously coupled to a critical system.…
Photonic Feshbach Resonance
D. Z. Xu, H. Ian, T. Shi +2
Hermann Feshbach predicted fifty years ago that when two atomic nuclei are scattered within an open entrance channel-- the state observable at infinity, they may enter an intermedi…
Quantum Zeno switch for single-photon coherent transport
Lan Zhou, S. Yang, Yu-xi Liu +2
Using a dynamical quantum Zeno effect, we propose a general approach to control the coupling between a two-level system (TLS) and its surroundings, by modulating the energy level s…
On thermal stability of topological qubit in Kitaev's 4D model
R. Alicki, M. Horodecki, P. Horodecki +1
We analyse stability of the four-dimensional Kitaev model - a candidate for scalable quantum memory - in finite temperature within the weak coupling Markovian limit. It is shown th…
Quantum Optomechanics with Single Atom
Yue Chang, H. Ian, C. P. Sun
The recently increasing explorations for cavity optomechanical coupling assisted by a single atom or an atomic ensemble have opened an experimentally accessible fashion to interfac…
Observable Topological Effects of Mobius Molecular Devices
Nan Zhao, H. Dong, Shuo Yang +1
We study the topological properties of quantum states for the spinless particle hopping in a Mobius ladder. This system can be regarded as a molecular device possibly engineered fr…
Quantum super-cavity with atomic mirrors
Lan Zhou, H. Dong, Yu-xi Liu +2
We study single-photon transport in an array of coupled microcavities where two two-level atomic systems are embedded in two separate cavities of the array. We find that a single-p…
Lehmann-Symanzik-Zimmermann Reduction Approach to Multi-Photon Scattering in Coupled-Resonator Arrays
T. Shi, C. P. Sun
We present a quantum field theoretical approach based on the Lehmann-Symanzik-Zimmermann reduction for the multi-photon scattering process in a nano-architecture consisting of the…
An alternative quantum fidelity for mixed states of qudits
Xiaoguang Wang, Chang-Shui Yu, X. X. Yi
We give an alternative definition of quantum fidelity for two density operators on qudits in terms of the Hilbert-Schmidt inner product between them and their purity. It can be reg…
Induced Entanglement Enhanced by Quantum Criticality
Qing Ai, Tao Shi, Guilu Long +1
Two qubit entanglement can be induced by a quantum data bus interacting with them. In this paper, with the quantum spin chain in the transverse field as an illustration of quantum…
Intrinsic Cavity QED and Emergent Quasi-Normal Modes for Single Photon
H. Dong, Z. R. Gong, H. Ian +2
We propose a special cavity design that is constructed by terminating a one-dimensional waveguide with a perfect mirror at one end and doping a two-level atom at the other. We show…
Effective Hamiltonian approach to the Kerr nonlinearity in an optomechanical system
Z. R. Gong, H. Ian, Yu-xi Liu +2
Using the Born-Oppenheimer approximation, we derive an effective Hamiltonian for an optomechanical system that leads to a nonlinear Kerr effect in the system's vacuum. The oscillat…
Controlling Quasibound States in 1D Continuum Through Electromagnetic Induced Transparency Mechanism
Z. R. Gong, H. Ian, Lan Zhou +1
We study the coherent scattering process of a single photon confined in an one-dimensional (1D) coupled cavity-array, where a -type three-level atom is placed inside one of the…

We theoretically study a cavity filled with atoms, which provides the optical-mechanical interaction between the modified cavity photonic field and a movable mirror at one end. We…
Fidelity susceptibility and long-range correlation in the Kitaev honeycomb model
Shuo Yang, Shi-Jian Gu, Chang-Pu Sun +1
We study exactly both the ground-state fidelity susceptibility and bond-bond correlation function in the Kitaev honeycomb model. Our results show that the fidelity susceptibility c…
Controlling soliton excitations in Heisenberg spin chain through magic angle
Jing Lu, Lan Zhou, Le-Man Kuang +1
We study the nonlinear dynamics of collective excitation in a -site quantum spin chain, which is manipulated by an oblique magnetic field. We show that, when the tilted fi…

Ming-Guang Hu, Dong-Ling Deng, Jing-Ling Chen
We investigate the maximal violations for both sides of the -dimensional CGLMP inequality by using the Bell operator method. It turns out that the maximal violations have a dece…
