Different roles of quantum interference in a quantum dot photocell with two intermediate bands
Shun-Cai Zhao, Jing-Yi Chen, Xin Li
It is generally believed that quantum interference can improve the transport of photo-generated carriers in a photocell, thereby improve the photoelectric conversion efficiency. In…
Negative refraction index manipulated by a displaced squeezed Fock state in the mesoscopic dissipative left-handed transmission line
Hong-Wei Guo, Shun-Cai Zhao, Xiao-Jing Wei
Negative refractive index (NRI) of the mescopic dissipative left-handed transmission line (LHTL) is manipulated by the displaced squeezed Fock state (DSFS) and the dissipation pres…
Localization of cold atom within half-wavelength domain
Shun-Cai Zhao, Xin Li, Ping Yang
Simulating the cold atom with a three-level quantum system interacting with two orthogonal standing-wave fields, the localization within half-wavelength domain in the x-y…
Dual peaks evoluting into single-peak for sub-wavelength 2-D atom localization in a V-type atomic system
Shun-Cai Zhao, Xin Li, Ping Yang
The atom localization of a V-type atomic system is discussed by the detunings associated with the probe and the two orthogonal standing-wave fields, and by the spontaneously genera…
Nonperturbative Dyson-Schwinger equation approach to strongly interacting Dirac fermion systems
Xiao-Yin Pan, Zhao-Kun Yang, Xin Li +1
Studying the strong correlation effects in interacting Dirac fermion systems is one of the most challenging problems in modern condensed matter physics. The long-range Coulomb inte…
Phase transition with trivial quantum criticality in anisotropic Weyl semimetal
Xin Li, Jing-Rong Wang, Guo-Zhu Liu
When a metal undergoes continuous quantum phase transition, the correlation length diverges at the critical point and the quantum fluctuation of order parameter behaves as a gaples…
Effect of decoherence on the Berry phase of a spin-half in a rotating magnetic field
Xin Li, Yu Shi
We investigate the decoherence effect of a bosonic bath on the Berry phase of a spin-1/2 in a time-dependent magnetic field, without making the Markovian approximation. A two-cycle…
Decoherence of quantum gates based on Aharonov-Anandan phases in a multistep scheme
Xin Li, Yu Shi
We study quantum decoherence of single-qubit and two-qubit Aharonov-Anandan (AA) geometric phase gates realized in a multistep scheme. Each AA gate is also compared with the dynami…
Quantum resonance scheme to determine the gravitational constant G
Zhiping Li, Xin Li
Building on the principles of quantum electrodynamics and special relativity, we develop a semi-classical QED theory of gravitation. The experiment model for theoretical analysis i…
Precision benchmark calculations for four particles at unitarity
Shahin Bour, Xin Li, Dean Lee +2
The unitarity limit describes interacting particles where the range of the interaction is zero and the scattering length is infinite. We present precision benchmark calculations fo…
Atomic Fermi gas at the unitary limit by quantum Monte Carlo methods: Effects of the interaction range
Xin Li, Jindrich Kolorenc, Lubos Mitas
We calculate the ground-state properties of unpolarized two-component Fermi gas by the diffusion quantum Monte Carlo (DMC) methods. Using an extrapolation to the zero effective ran…
