Partial K-way negativities and three tangle for three qubit states
S. Shelly Sharma, N. K. Sharma
We obtain, analytically, the global negativity, partial way negativities (K=2, 3), Wooter's tangle and three tangle for the generic three qubit canonical state. It is found tha…
Multipartite entanglement of three trapped ions in a cavity and W- State generation
S. Shelly Sharma, Eduardo de Almeida, Naresh K. Sharma
A scheme to generate three qubit maximally entangled W-states, using three trapped ions interacting with red sideband tuned single mode field of a high finesse cavity, is proposed.…
Quantum coherences, K-way negativities and multipartite entanglement
S. Shelly Sharma, N. K. Sharma
A characterization of N-partite states, based on K-way (K = 2 to N) negativities, is proposed. The K-way partial transpose with respect to a subsystem is defined so as to shift the…
Aproximative solutions to the neutrino oscillation problem in matter
Verissimo M. de Aquino, J. S. S. de Oliveira
We present approximative solutions to the neutrino evolution equation calculated by different methods. In a two neutrino framework, using the physical parameters which gives the ma…
Localization of Equivariant Cohomology for Compact and Non-compact Group Actions
A. A. Bytsenko, M. Libine, F. L. Williams
We give a brief introduction to the Berline-Vergne localization formula for the finite-dimensional setting and indicate how the Duistermaat-Heckman formula is derived from it. We c…
Physical Consonance Law of Sound Waves
Mario Goto
Sound consonance is the reason why it is possible to exist music in our life. However, rules of consonance between sounds had been found quite subjectively, just by hearing. To car…
