Derivations of plane algebroid curves
Sagnik Chakraborty, R. V. Gurjar, Madhuparna Pal
In this paper, we study the derivations of an irreducible plane algebroid curve , which is not regular. Since the normalization of is isomorphic to $k[…
Jaynes-Cummings dynamics in strong coupling for many-interacting-qubit quantum Rabi models
Roberto Grimaudo, Sagnik Chakraborty, Rosario Lo Franco +1
The present work focuses on the strong/weak interaction of many-body spin-systems with a cavity mode. It introduces the necessity of redefining the physical conditions determining…
Intrinsic Hamiltonian of Mean Force and Strong-Coupling Quantum Thermodynamics
Ignacio González, Sagnik Chakraborty, Ãngel Rivas
We present a universal thermodynamic framework for quantum systems that may be strongly coupled to thermal environments. Unlike previous approaches, our method enables a clear defi…
Three-Photon Saturable Absorption in Atomically Thin Phlogopite
Nabarun Mandal, Sagnik Chakraborty, Ranjeet Singh +10
Two-dimensional (2D) materials, due to their remarkable physical and chemical properties, hold significant potential for future optical and electrical applications. In this study,…
Efficient Estimation of Multiple Temperatures via a Collisional Model
Srijon Ghosh, Sagnik Chakraborty, Rosario Lo Franco
We present a quantum thermometric protocol for the estimation of multiple temperatures within the collisional model framework. Employing the formalism of multiparameter quantum met…
Monomial and binomial retracts of polynomial rings
Sagnik Chakraborty, Madhuparna Pal
Let be a ring and the polynomial ring in variables over . In this article, we consider retractions such that …
