Geometric phases for finite-dimensional systems -- the roles of Bargmann Invariants, Null Phase Curves and the Schwinger Majorana SU(2) framework
K S Akhilesh, Arvind, S Chaturvedi +2
We present a study of the properties of Bargmann Invariants (BI) and Null Phase Curves (NPC) in the theory of the geometric phase for finite dimensional systems. A recent suggestio…

Monogamous nature of symmetric multiqubt states with distinct spinors
Sudha, K. S. Akhilesh, B. G. Divyamani +2
Monogamy relations place restrictions on the shareability of quantum corellations in multipartite states. Being an intrinsic quantum feature, monogamy property throws light on {\em…

Spin squeezing in Dicke-class of states with non-orthogonal spinors
K. S. Akhilesh, K. S. Mallesh, Sudha +1
The celebrated Majorana representation is exploited to investigate spin squeezing in different classes of pure symmetric states of N qubits with two distinct spinors, namely the Di…
