State-dependent, addressable subwavelength lattices with cold atoms (2008)
Yi, W., Daley, A. J., Pupillo, G., Zoller, P.
We discuss how adiabatic potentials can be used to create addressable lattices on a subwavelength scale, which can be used as a tool for local operations and readout within a lattice substructure,...
Signal of Bose condensation in an optical lattice at finite temperature (2007)
We discuss the experimental signal for the Bose condensation of cold atoms in an optical lattice at finite temperature. Instead of using the visibility of the interference pattern via the...
We derive a set of general dynamical mean-field equations for strongly interacting fermionic atoms in arbitrary slowly varying potential traps. Our derivation generalizes the ansatz of the crossover...
Superfluid shells for trapped fermions with mass and population imbalance (2006)
We map out the phase diagram of strongly interacting fermions in a potential trap with mass and population imbalance between the two spin components. As a unique feature distinctively different from...
Detecting the breached pair phase in a polarized ultracold Fermi gas (2006)
We propose a method for the experimental detection of a new quantum phase, the breached pair state, in a strongly interacting ultracold Fermi gas with population imbalance. We show that through the...
Phase diagram of a polarized Fermi gas across a Feshbach resonance in a potential trap (2006)
We map out the detailed phase diagram of a trapped ultracold Fermi gas with population imbalance across a wide Feshbach resonance. We show that under the local density approximation, the properties...
We systematically study the BCS-BEC crossover and the quantum phase transition in ultracold 6Li and 40K atoms across a wide Feshbach resonance. The background scattering lengths for 6Li and 40K have...
Trapped Fermions across a Feshbach resonance with population imbalance (2005)
We investigate the phase separation of resonantly interacting fermions in a trap with imbalanced spin populations, both at zero and at finite temperatures. We directly minimize the thermodynamical...
Anisotropic Correlations in Epitaxial Iron Silicide: Contribution of Surface and Bulk States (2005)
Altfeder, I. B., Yi, W., Sander, D., Chen, D. M., Narayanamurti, V.
Using scanning tunneling microscopy we observed quasi-one-dimensional electronic states in two epitaxial phases of iron-silicide thin films. In a semiconducting beta-phase we succeeded to directly...
Dynamical mean-field equations for strongly interacting fermionic atoms in a potential trap (2005)
We derive a set of dynamical mean-field equations for strongly interacting fermionic atoms in a potential trap across a Feshbach resonance. Our derivation is based on a variational ansatz, which...
Dynamical Response of Fermi Condensate to Varying Magnetic Fields (2005)
We investigate the dynamical response of strongly interacting ultra-cold fermionic atoms near Feshbach resonance to varying magnetic fields. Following the experimental practices, we calculate the...
Crossover in Broad Feshbach Resonance with Energy-Dependent Coupling (2004)
This paper has been withdrawn by the authors as the recent measurement of the closed channel population for Li6 [Partridge et al., cond-mat/0505353] indicates that the cutoff energy is still much...
Adiabatic and non-adiabatic merging of independent Bose condensates (2004)
Motivated by a recent experiment [Chikkatur, et al. Science, 296, 2193 (2002)] on the merging of atomic condensates, we investigate how two independent condensates with random initial phases can...
Tunneling into Multiwalled Carbon Nanotubes: Coulomb Blockade and Fano Resonance (2003)
Yi, W., Lu, L., Hu, H., Pan, Z. W., Xie, S.
Tunneling spectroscopy measurements of single tunnel junctions formed between multiwalled carbon nanotubes (MWNTs) and a normal metal are reported. Intrinsic Coulomb interactions in the MWNTs give...
3 omega method for specific heat and thermal conductivity measurements (2002)
We present a 3 omega method for simultaneously measuring the specific heat and thermal conductivity of a rod- or filament-like specimen using a way similar to a four-probe resistance measurement. The...
