Ground-state properties of a supersymmetric fermion chain
Ground-state properties supersymmetric fermion chain
2010/12/27
We analyze the ground state of a strongly interacting fermion chain with a supersymmetry. We conjecture a number of exact results, such as a hidden duality between weak and strong couplings. By explo...
Hyperfine and Zeeman interactions of the $a(1)[^3\Sigma^+_1]$ state of PbO
Hyperfine Zeeman interactions
2010/11/16
The role of the interaction with the nearest electronic state $^3\Sigma^+_{0^-}$ on the hyperfine structure and magnetic properties of the $a(1)[^3\Sigma^+_1]$ state of PbO is assessed. The accountin...
Entanglement is the quintessential quantum phenomenon and a necessary ingredient in most emerging quantum technologies, including quantum repeaters, quantum information processing (QIP) and the strong...
Perfect state transfer, graph products and equitable partitions
Perfect state transfer graph products equitable partitions
2010/10/18
We describe new constructions of graphs which exhibit perfect state transfer on continuoustime
quantum walks. Our constructions are based on variants of the double cones [8, 3, 2] and
the Cartesian ...
