Doping dependence of Meissner effect in triangular-lattice superconductors
Ling Qin, Xixiao Ma, Lulin Kuang +2
In the spin-excitation-mediated pairing mechanism for superconductivity, the geometric frustration effects not only the spin configuration but also the superconducting-state proper…
Magnetic properties of spin-1/2 Fermi gases with ferromagnetic interaction
Baobao Wang, Jihong Qin, Huaiming Guo
We investigate the magnetic properties of spin- charged Fermi gases with ferromagnetic coupling via mean-field theory, and find the interplay among the paramagnetism, diamagne…
Effect of the pseudogap on the infrared response in cuprate superconductors
Ling Qin, Jihong Qin, Shiping Feng
One of the most essential aspects of cuprate superconductors is a large pseudogap coexisting with a superconducting gap, then some anomalous properties can be understood in terms o…
Quantum pumping induced by disorder in one dimension
Jihong Qin, Huaiming Guo
The topological property in one dimension (1D) is protected by symmetry. Based on a concrete model, we show that since a 1D topological model usually contain two of the three Pauli…
Magnetic properties of two-dimensional charged spin-1 Bose gases
Yingxue Chen, Jihong Qin, Qiang Gu
Within the mean-field theory, we investigate the magnetic properties of a charged spin-1 Bose gas in two dimension. In this system the diamagnetism competes with paramagnetism, whe…
Pseudogap and charge dynamics in doped cuprates
Ling Qin, Jihong Qin, Shiping Feng
Within the microscopic theory of the normal-state pseudogap state, the doping and temperature dependence of the charge dynamics in doped cuprates is studied in the whole doping ran…
