Quantum Dynamics under continuous projective measurements: non-Hermitian description and the continuous space limit
Varun Dubey, Cedric Bernardin, Abhishek Dhar
The problem of the time of arrival of a quantum system in a specified state is considered in the framework of the repeated measurement protocol and in particular the limit of conti…
How Archimedes showed that is approximately equal to 22/7
Damini D. B., Abhishek Dhar
The ratio of the circumference, C, of a circle to its diameter, D, is a constant number denoted by and is independent of the size of the circle. It is known that is an irra…
Transport in spinless superconducting wires
Junaid Majeed Bhat, Abhishek Dhar
We consider electron transport in a model of a spinless superconductor described by a Kitaev type lattice Hamiltonian where the electron interactions are modelled through a superco…
Revisiting the Mazur bound and the Suzuki equality
Abhishek Dhar, Aritra Kundu, Keiji Saito
Among the few known rigorous results for time-dependent equilibrium correlations, important for understanding transport properties, are the Mazur bound and the Suzuki equality. The…
Quantum Brownian Motion: Drude and Ohmic Baths as Continuum Limits of the Rubin Model
Avijit Das, Abhishek Dhar, Ion Santra +2
The motion of a free quantum particle in a thermal environment is usually described by the quantum Langevin equation, where the effect of the bath is encoded through a dissipative…
COVID-19: Analytic results for a modified SEIR model and comparison of different intervention strategies
Arghya Das, Abhishek Dhar, Srashti Goyal +2
The Susceptible-Exposed-Infected-Recovered (SEIR) epidemiological model is one of the standard models of disease spreading. Here we analyse an extended SEIR model that accounts for…
