Stochastic thermodynamics and the Ericsson nano engine -- Efficiency from equilibrium results
Jasleen Kaur, Aritra Ghosh, Sushanta Dattagupta +2
In this work, we study an Ericsson cycle whose working substance is a charged (quantum) oscillator in a magnetic field that is coupled to a heat bath. The resulting quantum Langevi…
Quantum transport under oscillatory drive with disordered amplitude
Vatsana Tiwari, Sushanta Dattagupta, Devendra Singh Bhakuni +1
We investigate the dynamics of non-interacting particles in a one-dimensional tight-binding chain in the presence of an electric field with random amplitude drawn from a Gaussian d…
Dephasing-Induced Distribution of Entanglement in Tripartite Quantum Systems
Sovik Roy, Md. Manirul Ali, Abhijit Mandal +1
Preserving multipartite entanglement amidst decoherence poses a pivotal challenge in quantum information processing. However, assessing multipartite entanglement in mixed states am…
Teleportation of unknown qubit via Star type tripartite states
Anushree Pandey, Abhijit Mandal, Sovik Roy
Eylee Jung \textit{et.al}\cite{jung2008} had conjectured that is a necessary and sufficient condition for the perfect two-party teleportation and consequently…
Form Invariance of Raychaudhuri equation in the presence of Inflaton-type fields
Arijit Panda, Debashis Gangopadhyay, Goutam Manna
We show that the Raychaudhuri equation remains form invariant for certain solutions of scalar fields whose Lagrangian is non-canonical and of the form $\mathcal{L}(X,ϕ)=-V(ϕ)F(…
Weak-coupling limits of the quantum Langevin equation for an oscillator
Aritra Ghosh, Sushanta Dattagupta
The quantum Langevin equation as obtained from the independent-oscillator model describes a strong-coupling situation, devoid of the Born-Markov approximation that is employed in t…
Constraining Cosmological Parameters with Viscous Modified Chaplygin Gas and Generalized Cosmic Chaplygin Gas Models in Horava-Lifshitz Gravity: Utilizing Late-time Datasets
Sayani Maity, Himanshu Chaudhary, Ujjal Debnath +2
This study examines accelerated cosmic expansion using the Viscous Modified Chaplygin Gas (VMMG) and Generalized Cosmic Chaplygin Gas (GCCM) within Horava-Lifshitz gravity. Our aim…
