Spectral Crossovers and Universality in Quantum Spin-chains Coupled to Random Fields
Debojyoti Kundu, Santosh Kumar, Subhra Sen Gupta
We study the spectral properties of and spectral-crossovers between different random matrix ensembles (Poissonian, GOE, GUE) in correlated spin-chain systems, in the presence of ra…

Signatures of spectral crossovers in the short- and long-range spectral correlations of a disordered spin-chain with Kramers degeneracy
Debojyoti Kundu, Santosh Kumar, Subhra Sen Gupta
We investigate several distinct spectral crossovers amongst various integrable and quantum-chaotic limits of a 1D disordered quantum spin-1/2 model, by tuning the relative amplitud…
