Probing -Spin Correlations in Optical Lattices
Chuanwei Zhang, V. W. Scarola, S. Das Sarma
We propose a technique to measure multi-spin correlation functions of arbitrary range as determined by the ground states of spinful cold atoms in optical lattices. We show that an…
Anyonic Braiding in Optical Lattices
Chuanwei Zhang, V. W. Scarola, Sumanta Tewari +1
Topological quantum states of matter, both Abelian and non-Abelian, are characterized by excitations whose wavefunctions undergo non-trivial statistical transformations as one exci…
Quantum Computation Using Vortices and Majorana Zero Modes of a + Superfluid of Fermionic Cold Atoms
Sumanta Tewari, S. Das Sarma, Chetan Nayak +2
We propose to use the recently predicted two-dimensional `weak-pairing' superfluid state of fermionic cold atoms as a platform for topological quantum computation. In…
Manipulation of Single Neutral Atoms in Optical Lattices
Chuanwei Zhang, S. L. Rolston, S. Das Sarma
We analyze a scheme to manipulate quantum states of neutral atoms at individual sites of optical lattices using focused laser beams. Spatial distributions of focused laser intensit…
