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…
Late time dynamics in SUSY saddle-dominated scrambling through higher-point OTOC
Rathindra Nath Das, Sourav Dutta, Archana Maji
In this article, we study the scrambling dynamics in supersymmetric quantum mechanical systems. The eigenstate representation of such supersymmetric systems allows us to present an…
Coherence and path indistinguishability for the interference of multiple single-mode fields
Rathindra Nath Das, Sobhan Kumar Sounda
A well known result for the interference of two single-mode fields is that the degree of coherence and the degree of indistinguishablity are same when we consider the detection of…
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…
