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…
Friction of a driven chain: Role of momentum conservation, Goldstone and radiation modes
Debankur Das, Richard Vink, Matthias Krüger
We analytically study friction and dissipation of a driven bead in a 1D harmonic chain, and analyze the role of internal damping mechanism as well as chain length. Specifically, we…
Displacement correlations in disordered athermal networks
Debankur Das, Pappu Acharya, Kabir Ramola
We derive exact results for correlations in the displacement fields in near-crystalline athermal systems in two dimensions. We analyze the…
