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…

Resetting in a viscoelastic bath: the bath remembers
Ion Santra, Debankur Das
We study stochastic resetting of a probe particle in a viscoelastic environment where only the probe is reset while the medium retains memory of its past dynamics. Using a minimal…

Activated solids: Spontaneous deformations, non-affine fluctuations, softening, and failure
Parswa Nath, Debankur Das, Surajit Sengupta +1
Internal activity can fundamentally reshape the mechanical behavior of solids, yet its role in softening and failure remains incompletely understood. In this study, we investigate…
