Dissipative spectral form factor for elliptic Ginibre unitary ensemble and applications
Sunidhi Sen, Santosh Kumar, Ayana Sarkar +1
We investigate the dissipative spectral form factor (DSFF)--a widely used probe of non-Hermitian quantum chaos--in the elliptic Ginibre unitary ensemble (eGinUE), which interpolate…

Multifractal dimensions for orthogonal-to-unitary crossover ensemble
Ayana Sarkar, Ashutosh Dheer, Santosh Kumar
Multifractal analysis is a powerful approach for characterizing ergodic or localized nature of eigenstates in complex quantum systems. In this context, the eigenvectors of random m…
