Generalized Liénard systems and isochronous connections
Bijan Bagchi, A. Ghose-Choudhury, Aritra Ghosh +1
In this paper, we explore some classical and quantum aspects of the nonlinear Liénard equation , where is a real variable…
Pseudo-Hermitian extensions of the harmonic and isotonic oscillators
Aritra Ghosh, Akash Sinha
In this work, we describe certain pseudo-Hermitian extensions of the harmonic and isotonic oscillators, both of which are exactly-solvable models in quantum mechanics. By coupling…
Efficient Computation of Generalized Noncontextual Polytopes and Quantum violation of their Facet Inequalities
Soumyabrata Hazra, Debashis Saha, Anubhav Chaturvedi +2
Finding a set of empirical criteria fulfilled by any theory satisfying the generalized notion of noncontextuality is a challenging task of both operational and foundational importa…
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…
Failure of epistemic models to explain the antidistinguishability of quantum mixed preparations
Sagnik Ray, Visweshwaran R, Debashis Saha
We investigate the limits of epistemic models in reproducing the empirical predictions of general quantum preparations. This involves comparing the common quantum overlap determine…
Classifying Measurement Incompatibility under Classical Pre- and Post-Processing Operations
Arun Kumar Das, Saheli Mukherjee, Debashis Saha +2
Measurement incompatibility has proved to be an important resource for quantum information processing. In this work, we present an operational approach that leverages classical ope…
