Magnetic Quantum Phases of Ultracold Dipolar Gases in an Optical Superlattice
Xiangguo Yin, Lushuai Cao, Peter Schmelcher
We propose an effective Ising spin chain constructed with dipolar quantum gases confined in a one-dimensional optical superlattice. Mapping the motional degrees of freedom of a sin…
Stability and Tunneling Dynamics of a Dark-Bright Soliton Pair in a Harmonic Trap
E. T. Karamatskos, J. Stockhofe, P. G. Kevrekidis +1
We consider a binary repulsive Bose-Einstein condensate in a harmonic trap in one spatial dimension and investigate particular solutions consisting of two dark-bright (DB) solitons…
Bloch dynamics in lattices with long range hoppings
J. Stockhofe, P. Schmelcher
We study a discrete Schrödinger equation with arbitrary long range hopping terms under the influence of an external force. The impact of long range hoppings on the single particle…
Degeneracy and Inversion of Band Structure for Wigner Crystals on a Toroidal Helix
A. V. Zampetaki, J. Stockhofe, P. Schmelcher
We explore the formation of Wigner crystals for charged particles on a toroidal helix. Focusing on certain commensurate cases we show that the ground state undergoes a pitchfork bi…
Nonlinear dynamics of atoms in a crossed optical dipole trap
Rosario González-Férez, Manuel Iñarrea, J. Pablo Salas +1
We explore the classical dynamics of atoms in an optical dipole trap formed by two identical Gaussian beams propagating in perpendicular directions. The phase space is a mixture of…
Symmetries and transport in site-dependently driven quantum lattices
Thomas Wulf, Christoph Petri, Benno Liebchen +1
We explore the quantum dynamics of particles in a spatiotemporally driven lattice. A powerful numerical scheme is developed, which provides us with the Floquet modes and thus enabl…
