An analytical approach to quantum phase transitions of ultracold Bose systems in bipartite optical lattices: Along the avenue of Green's function
Zhi Lin, Jun Zhang, Yan Chen +1
In this paper, we present a generalized Green's function method which can be used to investigate the quantum phase transitions analytically in a systematic way for ultracold Bose s…
Quantum phase transitions of ultra-cold Bose system in non-rectangular optical lattices
Zhi Lin, Jun Zhang, Ying Jiang
In this paper, we investigate systematically the Mott-insulator-Superfluid quantum phase transitions for ultracold scalar bosons in triangular, hexagonal, as well as Kagomé optical…
Relation between directed polymers in random media and random bond dimer models
Ying Jiang, Thorsten Emig
We reassess the relation between classical lattice dimer models and the continuum elastic description of a lattice of fluctuating polymers. In the absence of randomness we determin…
Ordering of geometrically frustrated classical and quantum Ising magnets
Ying Jiang, Thorsten Emig
A systematic study of both classical and quantum geometric frustrated Ising models with a competing ordering mechanism is reported in this paper. The ordering comes in the classica…
String Picture of a Frustrated Quantum Magnet and Dimer Model
Ying Jiang, Thorsten Emig
We map a geometrically frustrated Ising system with transversal field generated quantum dynamics to a strongly anisotropic lattice of non-crossing elastic strings. The combined eff…
