Modified spin-wave theory with ordering vector optimization I: frustrated bosons on the spatially anisotropic triangular lattice
Philipp Hauke, Tommaso Roscilde, Valentin Murg +2
We investigate a system of frustrated hardcore bosons, modeled by an XY antiferromagnet on the spatially anisotropic triangular lattice, using Takahashi's modified spin-wave (MSW)…
Universal phase diagram of disordered bosons from a doped quantum magnet
Rong Yu, Stephan Haas, Tommaso Roscilde
A quantum particle cannot in general diffuse through a disordered medium because of its wavelike nature, but interacting particles can escape localization by collectively percolati…
Off-diagonal correlations in a one-dimensional gas of dipolar bosons
Tommaso Roscilde, Massimo Boninsegni
We present a quantum Monte Carlo study of the one-body density matrix (OBDM) and the momentum distribution of one-dimensional dipolar bosons, with dipole moments polarized perpendi…
Dynamical creation of a supersolid in asymmetric mixtures of bosons
Tassilo Keilmann, J. Ignacio Cirac, Tommaso Roscilde
We propose a scheme to dynamically create a supersolid state in an optical lattice, using an attractive mixture of mass-imbalanced bosons. Starting from a "molecular" quantum cryst…
Revealing Novel Quantum Phases in Quantum Antiferromagnets on Random Lattices
Rong Yu, Stephan Haas, Tommaso Roscilde
Quantum magnets represent an ideal playground for the controlled realization of novel quantum phases and of quantum phase transitions. The Hamiltonian of the system can be indeed m…
Quantum polarization spectroscopy of correlations in attractive fermionic gases
T. Roscilde, M. Rodriguez, K. Eckert +4
We show how spin-spin correlations, detected in a non-destructive way via spatially resolved quantum polarization spectroscopy, strongly characterize various phases realized in tra…
