Analytic Spread Complexity from Level Statistics: From Chaos to Integrability
Pallab Basu, Suman das, Bigboy Madlala
Spread complexity has emerged as a useful probe of quantum chaos, yet the microscopic spectral origin of its characteristic finite-time peak remains incompletely understood. We dev…

Complexity of Quadratic Quantum Chaos
Pallab Basu, Suman Das, Pratik Nandy
We investigate minimal two-body Hamiltonians with random interactions that generate spectra resembling those of Gaussian random matrices, a phenomenon we term quadratic quantum cha…

An Analytic Zeta Function Ramp at the Black Hole Thouless Time
Pallab Basu, Suman Das, Chethan Krishnan
Black hole normal modes have intriguing connections to logarithmic spectra, and the spectral form factor (SFF) of is the mod square of the Riemann zeta function (RZF…
