An agitated oscillator chain
Aaron Beyen, Christian Maes, Ion Santra
Reduced dynamical descriptions for spatially extended systems in contact with a nonequilibrium medium give essential information about extensions of fluctuation-dissipation relatio…
Negative Differential Heat Conductivity in a Harmonic Chain Coupled to a Particle Reservoir
Simon Krekels, Christian Maes, Ion Santra +1
When coupling thermal baths at different temperatures, negative differential thermal conductivity is typically attributed to nonlinear interactions in the connecting medium. In thi…
Specific heat of thermally driven chains
Michiel Gautama, Faezeh Khodabandehlou, Christian Maes +1
We investigate the thermal responses of a harmonic oscillator chain coupled at its boundaries to heat baths held at different temperatures. This setup sustains a steady energy flux…
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…
Exact Volterra series for mean field dynamics
Ion Santra, Matthias Krüger
We derive an exact Volterra series expansion for a mean field of an interacting particle system subject to a potential perturbation, expressing the Volterra expansion kernels in te…
Tracer dynamics in an interacting active bath: fluctuations and energy partition
Ritwick Sarkar, Ion Santra
We investigate the dynamics of a massive tracer particle coupled to an interacting active bath, modeled as a harmonic chain of overdamped active particles analytically, with an aim…
Forces from coarse-graining nonequilibrium degrees of freedom: exact results
Ion Santra, Matthias Krüger
We explore the relaxation dynamics of a tracer in a harmonic trap coupled to a non-equilibrium bath particle in stationary state, finding qualitative differences compared to the we…
Classical Open Systems coupled to Nonlinear Baths: Noise Spectrum and Dynamical Correlations
Chitrak Bhadra, Ion Santra, Dhruba Banerjee
Open system dynamics in a classical setting is microscopically governed by the structure of the thermal environment which influences the dynamics of the probe particle (free or in…
