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…

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…
