'Electron' and 'photon' emerging from supersymmetric neutral particles: A possible realization in ultracold Bose-Fermi atom mixture
Yue Yu, S. T. Chui
We show that the 'electron' and 'photon' can emerge from a supersymmetric Hubbard model which is a non-relativistic theory of the neutral particles. The Higgs boson and 'photon' ma…
Anisotropic transport for FQH state at intermediate magnetic field
Shi-Jie Yang, Yue Yu, Bang-Fen Zhu
The state is spin-unpolarized at weak magnetic field and fully polarized at strong field. At intermediate field, a plateau of half the maximal polarization is observed. We…
Interaction of a surface acoustic wave with a two-dimensional electron gas
Shi-Jie Yang, Hu Zhao, Yue Yu
When a surface acoustic wave propagates on the surface of a GaAs semiconductor, coupling between electrons in the two-dimensional electron gas beneath the interface and the elastic…
One-band Hubbard model with hopping asymmetry and the effective theory at finite U: Phase diagram and metal-insulator transition
Yuchuan Wen, Yue Yu
We study the one-band Hubbard model at half filling with hopping asymmetry and its effective model at finite but large U up to the second order of tmix/U. Two variational wave func…
Short-range coherence of a lattice Bose atom gas in the Mott insulating phase
Yue Yu
We study the short-range coherence of ultracold lattice Bose gases in the Mott insulating phase. We calculate the visibility of the interference pattern and the results agree quant…
Slave particle approach to the finite temperature properties of ultracold Bose gases in optical lattices
Xiancong Lu, Jinbin Li, Yue Yu
By using slave particle (slave boson and slave fermion) technique on the Bose-Hubbard model, we study the finite temperature properties of ultracold Bose gases in optical lattices.…
Incompressible excitonic superfluid of ultracold Bose atoms in an optical lattice: a new superfluid phase in the one-component Bose-Hubbard model
Yue Yu
We predict that a new superfluid phase, the incompressible excitonic superfluid (IESF), in the phase diagram of ultracold Bose atoms in dimensional optical lattices, which is…
