Chaos from quantum bath fluctuations
Ilan Baud, Tamoghna Ray, Mahaveer Prasad +2
The effect of a large environment on a finite-size quantum mechanical system is two-fold: It brings dissipation, but also fluctuations of thermal and quantum origin. While dissipat…

Assessment of spectral phases of non-Hermitian quantum systems through complex and singular values
Mahaveer Prasad, S. Harshini Tekur, Bijay Kumar Agarwalla +1
Chaotic behavior or lack thereof in non-Hermitian systems is often diagnosed via spectral analysis of associated complex eigenvalues. Very recently, singular values of the associat…
