Realizing Fractional Chern Insulators with Dipolar Spins
Norman Y. Yao, Alexey V. Gorshkov, Chris R. Laumann +3
Strongly correlated quantum systems can exhibit exotic behavior controlled by topology. We predict that the ν=1/2 fractional Chern insulator arises naturally in a two-dimensional a…
Entanglement spectrum of the two dimensional Bose-Hubbard model
Vincenzo Alba, Masudul Haque, Andreas M. Laeuchli
We study the entanglement spectrum (ES) of the Bose-Hubbard model on the two dimensional square lattice at unit filling, both in the Mott insulating and in the superfluid phase. In…
Shell-Filling Effect in the Entanglement Entropies of Spinful Fermions
Fabian H. L. Essler, Andreas M. Läuchli, Pasquale Calabrese
We consider the von Neumann and Rényi entropies of the one dimensional quarter-filled Hubbard model. We observe that for periodic boundary conditions the entropies exhibit an unexp…
Hierarchy of fractional Chern insulators and competing compressible states
A. M. Läuchli, Z. Liu, E. J. Bergholtz +1
We study the phase diagram of interacting electrons in a dispersionless Chern band as a function of their filling. We find hierarchy multiplets of incompressible states at fillings…
Effective Spin Couplings in the Mott Insulator of the Honeycomb Lattice Hubbard Model
H-Y. Yang, A. F. Albuquerque, S. Capponi +2
Motivated by the recent discovery of a spin liquid phase for the Hubbard model on the honeycomb lattice at half-filling, we apply both perturbative and non-perturbative techniques…
Fractional Chern Insulators in Topological Flat bands with Higher Chern Number
Zhao Liu, Emil J. Bergholtz, Heng Fan +1
Lattice models forming bands with higher Chern number offer an intriguing possibility for new phases of matter with no analogue in continuum Landau levels. Here, we establish the e…
