Spectral and Eigenvector Crossovers in Random Mixed Graphs
Himanshu Shekhar, Hrishidev Unni, Santosh Kumar +1
We study the spectral and eigenvector properties of random mixed graphs, combining undirected and directed interactions, using random matrix theory (RMT). The network is represente…
Spectral statistics of interpolating random circulant matrix and its applications to random circulant graphs
Sunidhi Sen, Himanshu Shekhar, Santosh Kumar
We consider a versatile matrix model of the form , where and are real random circulant matrices with independent but, in general, nonidentica…
Spectral crossover in non-hermitian spin chains: comparison with random matrix theory
Ayana Sarkar, Sunidhi Sen, Santosh Kumar
We systematically study the short range spectral fluctuation properties of three non-hermitian spin chain hamiltonians using complex spacing ratios. In particular we focus on the n…
Optical MIMO communication with unequal power allocation to channels
Aritra Laha, Santosh Kumar
Multiple input multiple output (MIMO) approach in fiber optical communication has emerged as an effective proposition to address the ever increasing demand for information exchange…
Random density matrices: Analytical results for mean fidelity and variance of squared Bures distance
Aritra Laha, Santosh Kumar
One of the key issues in quantum information theory related problems concerns with that of distinguishability of quantum states. In this context, Bures distance serves as one of th…
Random density matrices: Analytical results for mean root fidelity and mean square Bures distance
Aritra Laha, Agrim Aggarwal, Santosh Kumar
Bures distance holds a special place among various distance measures due to its several distinguished features and finds applications in diverse problems in quantum information the…
