Probing the localization effects in Krylov basis
J. Bharathi Kannan, Sreeram PG, Sanku Paul +2
Krylov complexity (K-complexity) is a measure of quantum state complexity that minimizes wavefunction spreading across all the possible bases. It serves as a key indicator of opera…

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…
