Efficient quantum state preparation using Stern-Gerlach effect on cold atoms
Vivek Singh, V. B. Tiwari, S. R. Mishra
The Zeeman hyperfine state dependent force in a Stern-Gerlach (SG) experiment has been exploited to separate and detect atoms having different Zeeman hyperfine states in a cold ato…
Polymorphism in Bi-based perovskite oxides: a first-principles study
Akansha Singh, Viveka N. Singh, Enric Canadell +2
Under normal conditions, bulk crystals of BiScO , BiCrO, BiMnO, BiFeO, and BiCoO present three very different variations of the perovskite structure: an antipol…
Numerically exact full counting statistics of the nonequilibrium Anderson impurity model
Michael Ridley, Viveka Nand Singh, Emanuel Gull +1
The time dependent full counting statistics of charge transport through an interacting quantum junction is evaluated from its generating function, controllably computed with the in…
Tellurium-bridged two-leg spin ladder in BaCuTeO
G. Narsinga Rao, R. Sankar, Akansha Singh +5
We present single-crystal growth and magnetic property studies of tellurium-bridged copper spin-1/2 system BaCuTeO. The spin-exchange interaction among copper spins via Cu-…
Antiferromagnetism of Ni2NbBO6 with S = 1 dimer quasi-one-dimensional armchair chains
G. Narsinga Rao, Viveka Nand Singh, R. Sankar +3
Long range antiferromagnetic (AFM) ordering of Ni spins in Ni2NbBO6 has been studied with single crystal from spin susceptibility measurement and comparedwith the ab initio calcula…
Radio frequency spectroscopy of the attractive Hubbard model in a trap
Sanjoy Datta, Viveka Nand Singh, Pinaki Majumdar
Attractive interaction between fermions can lead to pairing and superfluidity in an optical lattice. In contrast to the `continuum', on a lattice the trap induced density variation…
