The origin of amplitude chaos and strings
Pallab Basu, Anurag Sarkar
We analytically study the peak statistics of an amplitude ensemble to identify the local mechanism responsible for peak repulsion. Our analytical approaches show that a smooth, non…
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…
On Aspects of Spontaneous Symmetry Breaking in Rindler and Anti-de Sitter spacetimes for the Linear Sigma Model
Pallab Basu, Haridev S R, Prasant Samantray
We investigate aspects of spontaneous breakdown of symmetry for symmetric linear sigma model in the background of Rindler and Anti-de Sitter spacetimes respectively. In the…
On the Observer Dependence of the Quantum Effective Potential
Pallab Basu, Haridev S R, Prasant Samantray
In this short paper, we investigate the consequences of observer dependence of the quantum effective potential for an interacting field theory. Specializing to dimensional Eu…
