Realization of SU(2)*SU(6) Fermi System [PDF]
, 2010 We report the realization of a novel degenerate Fermi mixture with an SU(2)*SU(6) symmetry in a cold atomic gas. We successfully cool the mixture of the two fermionic isotopes of ytterbium 171Yb with the nuclear spin I=1/2 and 173Yb with I=5/2 below the ...

Temporal non-equilibrium dynamics of a Bose–Josephson junction in presence of incoherent excitations
New Journal of Physics, 2015 The time-dependent non-equilibrium dynamics of a Bose–Einstein condensate (BEC) typically generates incoherent excitations out of the condensate due to the finite frequencies present in the time evolution.

Laser assisted tunneling in a Tonks–Girardeau gas
New Journal of Physics, 2016 We investigate the applicability of laser assisted tunneling in a strongly interacting one-dimensional (1D) Bose gas (the Tonks–Girardeau gas) in optical lattices.

Rice–Mele model with topological solitons in an optical lattice
New Journal of Physics, 2015 Attractive ultracold fermions trapped in a one-dimensional periodically shaken optical lattice are considered. For an appropriate resonant shaking, a dimerized structure emerges for which the system realizes paradigmatic physics described by the Rice ...

Emergence of junction dynamics in a strongly interacting Bose mixture
New Journal of Physics, 2018 We study the dynamics of a one-dimensional system composed of a bosonic background and one impurity in single- and double-well trapping geometries.

Ab initio lattice results for Fermi polarons in two dimensions [PDF]
, 2015 We investigate the attractive Fermi polaron problem in two dimensions using non-perturbative Monte Carlo simulations. We introduce a new Monte Carlo algorithm called the impurity lattice Monte Carlo method.

Spin-orbit coupled repulsive Fermi atoms in a one-dimensional optical lattice
New Journal of Physics, 2015 Motivated by recent experimental development, we investigate spin–orbit coupled repulsive Fermi atoms in a one-dimensional optical lattice. Using the density-matrix renormalization group method, we calculate the momentum distribution function, gap, and ...

Robustness of discrete semifluxons in closed Bose–Hubbard chains
New Journal of Physics, 2016 We present the properties of the ground state and low-energy excitations of Bose–Hubbard chains with a geometry that varies from open to closed and with a tunable twisted link.

Statistics of the work distribution for a quenched Fermi gas
New Journal of Physics, 2014 The local quench of a Fermi gas, giving rise to the Fermi edge singularity and the Anderson orthogonality catastrophe, is an analytically tractable out-of-equilibrium problem in condensed matter.

Synthetic topological Kondo insulator in a pumped optical cavity
New Journal of Physics, 2018 Motivated by experimental advances on ultracold atoms coupled to a pumped optical cavity, we propose a scheme for synthesizing and observing the Kondo insulator in Fermi gases trapped in optical lattices.
