Ultrafast configuration changes and anomalous diffusion of an aromatic adsorbate on rare-gas nanoparticles
Arne Morlok, Philipp Elsässer, Yilin Li +5
Nanoparticles (NPs) exhibit tunable catalytic properties and serve as nanoreactors for controlled multimolecular chemistry. The kinetics and reactivity of such systems are critical…
How wrong is too wrong: A numerical study on the relevance of positional memory in the generalized Langevin equation
Abhir Mehrotra, Fabian Koch, Tanja Schilling
If a generalized Langevin equation contains a potential of mean force, it cannot at the same time contain a linear memory kernel and a fluctuating force that obeys a second fluctua…
Generalised Langevin Dynamics: Significance and Limitations of the Projection Operator Formalism
Christoph Widder, Tanja Schilling
We discuss some mathematical aspects of the Mori-Zwanzig projection operator formalism. The core of the Mori-Zwanzig formalism is the generalised Langevin equation, which is typica…
Snap, Crackle, and Pop: This is why the potential of mean force clashes with the fluctuation dissipation relation
Fabian Koch, Tabita Wasmer, Tanja Schilling
We analyze the non-linear generalized Langevin equation which contains a thermodynamic force. We show that even for systems in thermal equilibrium the presence of the thermodynamic…
On the generalized Langevin equation and the Mori projection operator technique
Christoph Widder, Johannes Zimmer, Tanja Schilling
In statistical physics, the Nakajima-Mori-Zwanzig projection operator formalism is used to derive an integro-differential equation for observables in a Hilbert space, the generaliz…
The concept of minimal dissipation and the identification of work in autonomous systems: A view from classical statistical physics
Anja Seegebrecht, Tanja Schilling
Recently, the concept of minimal dissipation has been brought forward as a means to define work performed on open quantum systems [Phys. Rev. A 105, 052216 (2022)]. We discuss this…
Tracer dynamics in polymer networks: generalized Langevin description
Sebastian Milster, Fabian Koch, Christoph Widder +2
Tracer diffusion in polymer networks and hydrogels is relevant in biology and technology, while it also constitutes an interesting model process for the dynamics of molecules in fl…
The non-equilibrium solvent response force: What happens if you push a Brownian particle
Fabian Koch, Jona Erle, Tanja Schilling
In this letter we discuss how to add forces to the Langevin equation. We derive the exact generalized Langevin equation for the dynamics of one particle subject to an external forc…
Optimizing the Structure of Acene Clusters
Philipp Elsässer, Tanja Schilling
We present a study of the potential energy surface (PES) of anthracene, tetracene and pentacene clusters with up to 30 molecules. We have applied the basin-hopping Monte Carlo (BHM…
