Modified spin-wave theory with ordering vector optimization II: Spatially anisotropic triangular lattice and model with Heisenberg interactions
Philipp Hauke, Tommaso Roscilde, Valentin Murg +2
We study the ground state phases of the Heisenberg quantum antiferromagnet on the spatially anisotropic triangular lattice and on the square lattice with up to next-next-ne…
Comment on "Feshbach-Einstein Condensates" by V. G. Rousseau and P. J. H. Denteneer
María Eckholt, Tommaso Roscilde
In a recent paper (Phys. Rev. Lett. 102, 015301 (2009), arXiv:0810.3763) Rousseau and Denteneer claim that an unconventional "super-Mott" (SM) phase is realized by bosons trapped i…
Magnetic Bose glass phases of coupled antiferromagnetic dimers with site dilution
Rong Yu, Omid Nohadani, Stephan Haas +1
We numerically investigate the phase diagram of two-dimensional site-diluted coupled dimer systems in an external magnetic field. We show that this phase diagram is characterized b…
Localization of cold atoms in state-dependent optical lattices via a Rabi pulse
Birger Horstmann, Stephan Dürr, Tommaso Roscilde
We propose a novel realization of Anderson localization in non-equilibrium states of ultracold atoms trapped in state-dependent optical lattices. The disorder potential leading to…
Exploring the grand-canonical phase diagram of interacting bosons in optical lattices by trap squeezing
Tommaso Roscilde
In this paper we theoretically discuss how quantum simulators based on trapped cold bosons in optical lattices can explore the grand-canonical phase diagram of homogeneous lattice…
