Arbitrary order transfer matrix exceptional points and van Hove singularities
Madhumita Saha, Bijay Kumar Agarwalla, Manas Kulkarni +1
In lattice models with quadratic finite-range Hermitian Hamiltonians, the inherently non-Hermitian transfer matrix (TM) governs the band dispersion. The van Hove singularities (VHS…
Effect of order of transfer matrix exceptional points on transport at band edges
Madhumita Saha, Bijay Kumar Agarwalla, Manas Kulkarni +1
Recently, it has been shown that, in one dimensional fermionic systems, close to band edges, the zero temperature conductance scales as , where is the system length. Thi…
Generalised Hydrodynamics description of the Page curve-like dynamics of a freely expanding fermionic gas
Madhumita Saha, Manas Kulkarni, Abhishek Dhar
We consider an analytically tractable model that exhibits the main features of the Page curve characterizing the evolution of entanglement entropy during evaporation of a black hol…
