Bilayer Coherent and Quantum Hall Phases: Duality and Quantum Disorder
(American Physical Society (APS), 2001)
We consider a fully spin-polarized quantum Hall system with no interlayer tunneling at total filling factor n 3 1 k (where k is an odd integer) using the Chern-Simons-Ginzburg-Landau theory. Exploit- ing particle-vortex ...
Bilayer paired quantum Hall states and Coulomb drag
(American Physical Society (APS), 2001)
We consider a number of strongly correlated quantum Hall states that are likely to be realized in bilayer quantum Hall systems at total Landau level filling fraction T 1. One state, the (3,3, 1) state, can occur as an ...
Magnetoplasmon excitations and spin density instabilities in an integer quantum Hall system with a tilted magnetic field
(American Physical Society (APS), 2002)
We study the magnetoplasmon collective-mode excitations of integer quantum Hall systems in a paraboli- cally confined quantum well nanostructure in the presence of a tilted magnetic field by using the time- dependent ...
Searching for a supersolid in cold-atom optical lattices
(American Physical Society (APS), 2006)
We suggest a technique for the observation of a predicted supersolid phase in extended Bose–Hubbard models which are potentially realizable in cold-atom optical lattice systems. In particular, we discuss important subtleties ...
Spontaneous symmetry breaking and exotic quantum orders in integer quantum Hall systems under a tilted magnetic field
(American Physical Society (APS), 2003)
We use the microscopic Hartree-Fock approximation to investigate various quantum phase transitions associated with possible spontaneous symmetry breaking induced by a tilted magnetic field in the integral quantum Hall QH ...
