Nonequilibrium Green's functions (NEGF) have emerged as a pivotal theoretical framework for investigating the time-dependent behaviour of quantum many-body systems. By tracking the evolution of ...

Optimal pointwise estimates are derived for the biharmonic Green function under Dirichlet boundary conditions in arbitrary C4,γ-smooth domains. Maximum principles do not exist for fourth order ...

This month Tom Rother, scientist at IMF, published the book “Green’s Functions in Classical Physics” in the book series Lecture Notes in Physics released by Springer. The book presents the Green’s ...
