Geometric Quantum Discord Signals Non-Factorization
Souvik Banerjee, Pablo Basteiro, Rathindra Nath Das +1
We propose the information-theoretic quantity of geometric quantum discord (GQD) as an indicator of the factorization properties of a given quantum system. In particular, we show h…
Aperiodic spin chains at the boundary of hyperbolic tilings
Pablo Basteiro, Rathindra Nath Das, Giuseppe Di Giulio +1
In view of making progress towards establishing a holographic duality for theories defined on a discrete tiling of the hyperbolic plane, we consider a recently proposed boundary sp…
The Generalized OTOC from Supersymmetric Quantum Mechanics: Study of Random Fluctuations from Eigenstate Representation of Correlation Functions
Kaushik Y. Bhagat, Baibhab Bose, Sayantan Choudhury +7
The concept of out-of-time-ordered correlation (OTOC) function is treated as a very strong theoretical probe of quantum randomness, using which one can study both chaotic and non-c…
Indirect detection of Cosmological Constant from interacting open quantum system
Subhashish Banerjee, Sayantan Choudhury, Satyaki Chowdhury +4
We study the indirect detection of Cosmological Constant from an open quantum system of interacting spins, weakly interacting with a thermal bath, a massless scalar field minimally…
