Correlated Phases of Bosons in Tilted Frustrated Lattices
Pielawa, Susanne; Kitagawa, Takuya; Berg, Erez; Sachdev, Subir (American Physical Society, 2011)We study the "tilting" of Mott insulators of bosons into metastable states. These are described by Hamiltonians acting on resonant subspaces, and have rich possibilities for correlated phases with non-trivial entanglement ... -
Frustrated Quantum Ising Spins Simulated by Spinless Bosons in a Tilted Lattice: From a Quantum Liquid to Antiferromagnetic Order
Pielawa, Susanne; Berg, Erez; Sachdev, Subir (American Physical Society, 2012)We study spinless bosons in a decorated square lattice with a near-diagonal tilt. The resonant subspace of the tilted Mott insulator is described by an effective Hamiltonian of frustrated quantum Ising spins on a nonbipartite ... -
Ramsey Interference in One-Dimensional Systems: The Full Distribution Function of Fringe Contrast as a Probe of Many-Body Dynamics
Kitagawa, Takuya; Pielawa, Susanne; Imambekov, Adilet; Schmiedmayer, Jörg; Gritsev, Vladimir; Demler, Eugene A. (American Physical Society, 2010)We theoretically analyze Ramsey interference experiments in one-dimensional quasicondensates and obtain explicit expressions for the time evolution of full distribution functions of fringe contrast. We show that distribution ...
