Exotic Node Line in ternary MgSrSi-type crystals
Jinling Lian, Lixian Yu, Qi-Feng Liang +3
Node line (NL) band-touchings protected by mirror symmetry (named as -NL), the product of inversion and time reversal symmetry (-NL), or nonsymmorphic symmet…
Creating a tunable spin squeezing via a time-dependent collective atom-photon coupling
Lixian Yu, Jingtao Fan, Shiqun Zhu +3
We present an experimentally feasible method to produce a large and tunable spin squeezing when an ensemble of many four-level atoms interacts simultaneously with a single-mode pho…
Quantum phases in circuit QED with a superconducting qubit array
Yuanwei Zhang, Lixian Yu, J. -Q. Liang +3
Circuit QED on a chip has become a powerful platform for simulating complex many-body physics. In this report, we realize a Dicke-Ising model with an antiferromagnetic nearest-neig…
Analytical solutions for the Rabi model
Lixian Yu, Shiqun Zhu, Qifeng Liang +2
The Rabi model that describes the fundamental interaction between a two-level system with a quantized harmonic oscillator is one of the simplest and most ubiquitous models in moder…
Quantum resonant effect of the strongly-driven spin-boson model
Qifeng Liang, Lixian Yu, Gang Chen +1
In this paper we discuss both analytically and numerically the rich quantum dynamics of the spin-boson model driven by a time-independent field of photon. Interestingly, we predict…
