Monotonicity of eigenstate thermalization hypothesis in two-dimensional systems
Nilakash Sorokhaibam, Anjan Daimari
We study numerically the enveloping -function of the fluctuation term in eigenstate thermalization hypothesis (ETH) statement. We concentrate on the energy (or entropy) dependen…
ETH-monotonicity and the black hole singularity
Nilakash Sorokhaibam
We study the enveloping function of the fluctuation term in eigenstate thermalization hypothesis (ETH) statement for holographic conformal field theories. We use this function to i…
A measure of chaos from eigenstate thermalization hypothesis
Nilakash Sorokhaibam
Eigenstate thermalization hypothesis is a detailed statement of the matrix elements of few-body operators in energy eigenbasis of a chaotic Hamiltonian. Part of the statement is th…
Quantum chaos and the arrow of time
Nilakash Sorokhaibam
We show that quantum chaotic many-body systems possess the thermodynamic arrow of time in the thermodynamic limit. Berry's conjecture in quantum chaotic systems and equivalence of…
Traversable wormhole without interaction
Nilakash Sorokhaibam
We show that strong quantum entanglement can support a stable traversable wormhole without any explicit interaction or tunnelling term between the two boundary theories of the worm…
Thermalization in different phases of charged SYK model
Tousik Samui, Nilakash Sorokhaibam
We study thermalization of charged SYK model in two different phases. We show that both the highly chaotic liquid phase and the dilute gas phase thermalize. Surprisingly the dilute…
Phase transition and chaos in charged SYK model
Nilakash Sorokhaibam
We study chaotic-integrable transition and the nature of quantum chaos in SYK model with chemical potential. We use a novel numerical technique to calculate the partition function…
Quantum Quenches and Thermalization in SYK models
Ritabrata Bhattacharya, Dileep P. Jatkar, Nilakash Sorokhaibam
We study non-equilibrium dynamics in SYK models using quantum quench. We consider models with two, four, and higher fermion interactions (, and higher) and use two differen…
Thermalization and non-monotonic entanglement growth in an exactly solvable model
Shruti Paranjape, Nilakash Sorokhaibam
We study quantum quenches and subsequent non-equilibrium dynamics of free Dirac fermions in 1+1 spacetime dimensions using time dependent mass. The final state is a normalized boun…
Thermalization in 2D critical quench and UV/IR mixing
Gautam Mandal, Shruti Paranjape, Nilakash Sorokhaibam
We consider quantum quenches in models of free scalars and fermions with a generic time-dependent mass that goes from to zero. We prove that, as anticipated in MSS \ci…
Thermalization with chemical potentials, and higher spin black holes
Gautam Mandal, Ritam Sinha, Nilakash Sorokhaibam
We study the long time behaviour of local observables following a quantum quench in 1+1 dimensional conformal field theories possessing additional conserved charges besides the ene…
The inside outs of AdS(3)/CFT(2): Exact AdS wormholes with entangled CFT duals
Gautam Mandal, Ritam Sinha, Nilakash Sorokhaibam
We present the complete family of solutions of 3D gravity (Lambda<0) with two asymptotically AdS exterior regions. The solutions are constructed from data at the two boundaries, wh…
