Projection operators in statistical mechanics: a pedagogical approach

Michael te Vrugt, Raphael Wittkowski

The Mori-Zwanzig projection operator formalism is one of the central tools of nonequilibrium statistical mechanics, allowing to derive macroscopic equations of motion from the micr…

Entropy, Shannon orbit equivalence, and sparse connectivity

David Kerr, Hanfeng Li

We say that two free probability-measure-preserving actions of countable groups are Shannon orbit equivalent if there is an orbit equivalence between them whose associated cocycle…

Overcoming the curse of dimensionality in the numerical approximation of parabolic partial differential equations with gradient-dependent nonlinearities

Martin Hutzenthaler, Arnulf Jentzen, Thomas Kruse

Partial differential equations (PDEs) are a fundamental tool in the modeling of many real world phenomena. In a number of such real world phenomena the PDEs under consideration con…

Control of the orbital character of indirect excitons in MoS2/WS2 heterobilayers

Jonas Kiemle, Florian Sigger, Michael Lorke +5

Valley selective hybridization and residual coupling of electronic states in commensurate van der Waals heterobilayers enable the control of the orbital character of interlayer exc…
