Pseudo-potential of a power-law decaying interaction in two-dimensional systems
Sheng-Min Shih, Daw-Wei Wang
We analytically derive the general pseudo-potential operator of an arbitrary isotropic interaction for particles confined in two-dimensional (2D) systems, using the frame work deve…
Collective excitations and instabilities in multi-layer stacks of dipolar condensates
Daw-Wei Wang, Eugene Demler
We analyze theoretically the collective mode dispersion in multi-layer stacks of two dimensional dipolar condensates and find a strong enhancement of the roton instability. We disc…
Confinement Induced Quantum Phase Transition and Polarization Cooling in a Dipolar Crystal of Polar Molecules
Yi-Ya Tian, Daw-Wei Wang
It is well-known that the liquid properties in a strongly confined system can be very different from their ordinary behaviors in an extended system, due to the competition between…
Cold Atoms and Molecules in Self-Assembled Dipolar Lattices
G. Pupillo, A. Griessner, A. Micheli +3
We study the realization of lattice models, where cold atoms and molecules move as extra particles in a dipolar crystal of trapped polar molecules. The crystal is a self-assembled…
An effective many-body theory for strongly interacting polar molecules
Daw-Wei Wang
We derive a general effective many-body theory for bosonic polar molecules in strong interaction regime, which cannot be correctly described by previous theories within the first B…
Quantum phase transitions of polar molecules in bilayer systems
Daw-Wei Wang
We investigate the quantum phase transitions of bosonic polar molecules in a two-dimensional double layer system. We show that an interlayer bound state of dipoles (dimers) can be…
Quantum fluids of self-assembled chains of polar molecules
Daw-Wei Wang, Mikhail D. Lukin, Eugene Demler
We study polar molecules in a stack of strongly confined pancake traps. When dipolar moments point perpendicular to the planes of the traps and are sufficiently strong, the system…
Magnetic disorder and dynamical properties of a Bose-Einstein condensate in atomic waveguides
Daw-Wei Wang
We systematically investigate the properties of the quenched disorder potential in an atomic waveguide, and study its effects to the dynamics of condensate in the strong disorder r…
Phase diagrams of one-dimensional Bose-Fermi mixtures of ultra-cold atoms
L. Mathey, D. -W. Wang
We study the quantum phase diagrams of Bose-Fermi mixtures of ultracold atoms confined to one dimension in an optical lattice. For systems with incommensurate densities, various qu…
Strong coupling theory for the superfluidity of Bose-Fermi mixtures
Daw-Wei Wang
We develop a strong-coupling theory for the superfluidity of fermion pairing phase in a Bose-Fermi mixture. Dynamical screening, self-energy renormalization, and a pairing gap func…
