Useful variants and perturbations of completely entangled subspaces and spans of unextendible product bases

Ritabrata Sengupta, Ajit Iqbal Singh

Finite dimensional entanglement for pure states has been used extensively in quantum information theory. Depending on the tensor product structure, even set of separable states can…

Ramsey theory for hypergroups

Vishvesh Kumar, Kenneth A. Ross, Ajit Iqbal Singh

In this paper, Ramsey theory for discrete hypergroups is introduced with emphasis on polynomial hypergroups, discrete orbit hypergroups and hypergroup deformations of semigroups. I…

Hypergroup Deformations of Semigroups

Vishvesh Kumar, Kenneth A. Ross, Ajit Iqbal Singh

We view the well-known example of the dual of a countable compact hypergroup, motivated by the orbit space of p-adic integers by Dunkl and Ramirez (1975), as hypergroup deformation…

Multilepton signals of heavier electroweakinos at the LHC

Manimala Chakraborti, Amitava Datta, Nabanita Ganguly +1

As sequel to a recent paper we examine the phenomenology of the full electroweakino sector of the pMSSM without invoking the adhoc but often employed assumption that the heavier on…

Evolution of worker policing

Jason W. Olejarz, Benjamin Allen, Carl Veller +2

Workers in insect societies are sometimes observed to kill male eggs of other workers, a phenomenon known as worker policing. We perform a mathematical analysis of the evolutionary…

Optimal quantum tomography with constrained elementary measurements arising from unitary bases

S. Chaturvedi, Sibasish Ghosh, K. R. Parthasarathy +1

The purpose of this paper is to introduce techniques of obtaining optimal ways to determine a d-level quantum state or distinguish such states. It entails designing constrained ele…

Reinvestigation of high pressure polymorphism in Hafnium metal

K. K. Pandey, Jyoti Gyanchandani, M. Somayazulu +3

There has been a recent controversy about the high pressure polymorphism of Hafnium (Hf). Unlike, the earlier known α ω structural transition at 38 8 GPa, Hrubi…

Role of Partial Transpose and Generalized Choi maps in Quantum Dynamical Semigroups involving Separable and Entangled States

Ajit Iqbal Singh

Power symmetric matrices defned and studied by R. Sinkhorn (1981) and their generalization by R.B. Bapat, S.K. Jain and K. Manjunatha Prasad (1999) have been utilized to give posit…
