Van Hove singularity-driven giant Nernst signal in twisted double bilayer graphene
Ujjal Roy, Monosij Roy, Unmesh Ghorai +8
Twisted graphene layers host van Hove singularities (vHSs), peaks in the electronic density of states, thought to drive exotic phases in moiré materials, but their effect on therma…
Tunable Chaos in the Finite Mean SYK Model
Arkaprava Mukherjee, Sumilan Banerjee, Sandip P. Trivedi +1
The complex Sachdev-Ye-Kitaev (SYK) model, featuring fermions with all-to-all interactions, serves as a dual paradigm for understanding non-Fermi liquid behavior and the holographi…
Multipartite information in sparse SYK models
Norihiro Iizuka, Arkaprava Mukherjee, Sunil Kumar Sake +1
In quantum field theories that admit gravity dual, specific inequalities involving entanglement entropy between arbitrary disjoint spatial regions hold. An example is the negativit…
Sparse random matrices and Gaussian ensembles with varying randomness
Takanori Anegawa, Norihiro Iizuka, Arkaprava Mukherjee +2
We study a system of qubits with a random Hamiltonian obtained by drawing coupling constants from Gaussian distributions in various ways. This results in a rich class of system…
Spectral Form Factor for Time-dependent Matrix model
Arkaprava Mukherjee, Shinobu Hikami
The quantum chaos is related to a Gaussian random matrix model, which shows a dip-ramp-plateau behavior in the spectral form factor for the large size . The spectral form factor…
Quantum randomness in the Sky
Sayantan Choudhury, Arkaprava Mukherjee
In this article, we study quantum randomness of stochastic cosmological particle production scenario using quantum corrected higher order Fokker Planck equation. Using the one to o…
A universal bound on Quantum Chaos from Random Matrix Theory
Sayantan Choudhury, Arkaprava Mukherjee
In this article, using the principles of Random Matrix Theory (RMT), we give a measure of quantum chaos by quantifying Spectral From Factor (SFF) appearing from the computation of…
Quantum Out-of-Equilibrium Cosmology
Sayantan Choudhury, Arkaprava Mukherjee, Prashali Chauhan +1
In this work, our prime focus is to study the one to one correspondence between the conduction phenomena in electrical wires with impurity and the scattering events responsible for…
