Memory with Onsager-Casimir symmetry: Rotating particle in a viscoelastic fluid
Debankur Das, Niloyendu Roy, Niklas Windbacher +2
We study the stochastic dynamics of a rotating Brownian particle in a non-Markovian fluid. Experimentally, we find that rotation enhances the long-time diffusivity of the particle…

A Single-granule Stirling Heat Engine
Niloyendu Roy, Pragya Arora, A K Sood +1
Single-particle heat engines at atomic and colloidal scales obey the universal thermodynamic bounds on work and efficiency. Here, we translate these principles to the macroscale by…
