The Luttinger liquid kink
Trinanjan Datta, E. W. Carlson, Jiangping Hu
Although the Tomonaga-Luttinger liquid exhibits spin-charge separation and the electron is not an elementary excitation of the system, nevertheless an effective electronic dispersi…
Majorana Fermions, Exact Mappings between Classical and Topological Orders
Han-Dong Chen, Jiangping Hu
Motivated by the duality between site-centered spin and bond-centered spin in one-dimensional system, which connects two different constructions of fermions from the same set of Ma…
Nature of the Quantum Phase Transition in Quantum Compass Model
Han-Dong Chen, Chen Fang, Jiangping Hu +1
In this work, we show that the quantum compass model on an square lattice can be mapped to a fermionic model with local density interaction. We introduce a mean-field approximation…
Vortex configurations of bosons in an optical lattice
Congjun Wu, Han-dong Chen, Jiang-ping Hu +1
The single vortex problem in a strongly correlated bosonic system is investigated self-consistently within the mean-field theory of the Bose-Hubbard model. Near the superfluid-Mott…
