Direct Lattice Shaking of Bose Condensates: Finite Momentum Superfluids
Abstract
Here, we address band engineering in the presence of periodic driving by numerically shaking a lattice containing a bosonic condensate. By not restricting to simplified band structure models we are able to address arbitrary values of the shaking frequency, amplitude, and interaction strengths g. For "nearresonant" shaking frequencies with moderate g, a quantum phase transition to a finite momentum superfluid is obtained with KibbleZurek scaling and quantitative agreement with experiment. We use this successful calibration as a platform to support a more general investigation of the interplay between (one particle) Floquet theory and the effects associated with arbitrary g. Band crossings lead to superfluid destabilization, but where this occurs depends on g in a complicated fashion.

Finitemomentum BoseEinstein condensates in shaken twodimensional square optical lattices
We consider ultracold bosons in a twodimensional square optical lattice described by the BoseHubbard model. In addition, an external timedependent sinusoidal force is applied to the system, which shakes the lattice along one of the diagonals. The effect of the shaking is to renormalize the nearestneighborhopping coefficients, which can be arbitrarily reduced, can vanish, or can even change sign, depending on the shaking parameter. Therefore, it is necessary to account for higherorderhopping terms, which are renormalized differently by the shaking, and to introduce anisotropy into the problem. We show that the competition between these different hopping terms leads to finitemomentummore » 
Generating macroscopicquantumsuperposition states in momentum and internalstate space from BoseEinstein condensates with repulsive interactions
Resonant Raman coupling between internal levels can create doublewell momentumspace potentials for multilevel 'periodicallydressed' atoms. We develop a manybody formalism for a weakly interacting, trapped periodically dressed Bose gas which illustrates how a tunable exchange interaction yields correlated manybody ground states. In contrast to the case of a positionspace double well, the ground state of stable periodicallydressed Bose gases with repulsive interactions tends toward a macroscopic superposition state in the regime where interactions dominate the momentumspace tunneling induced by the external trapping potential. We discuss how realtime control of experimental parameters can be used to create macroscopic quantum superpositions ofmore » 
Structure of excited vortices with higher angular momentum in BoseEinstein condensates
The structure of vortices in BoseEinstein condensed atomic gases is studied taking into account manybody correlation effects. It is shown that for excited vortices the particle density in the vortex core increases as the angular momentum of the system increases. The core density can increase by several times with only a few percent change in the angular momentum. This result provides an explanation for the observations in which the measured angular momentum is higher than the estimation based on counting the number of vortices and the visibility of the vortex cores is simultaneously reduced. The calculated density profiles for themore » 
Vortex Phase Qubit: Generating Arbitrary, Counterrotating, Coherent Superpositions in BoseEinstein Condensates via Optical Angular Momentum Beams
We propose a scheme for the generation of arbitrary coherent superpositions of vortex states in BoseEinstein condensates (BEC) using the orbitalangularmomentum states of light. We devise a scheme to generate coherent superpositions of two such counterrotating states of light using wellknown experimental techniques. We show that a specially designed Raman scheme allows for transfer of the optical vortexsuperposition state onto an initially nonrotating BEC. This creates an arbitrary and coherent superposition of a vortex and antivortex pair in the BEC. The ideas presented here could be extended to generate entangled vortex states, design memories for the orbitalangularmomentum states of light,more »
