The Dissipative Approach to Quantum Field Theory: Conceptual Foundations and Ontological Implications
Andrea Oldofredi, Hans Christian Öttinger
Many attempts have been made to provide Quantum Field Theory with conceptually clear and mathematically rigorous foundations; remarkable examples are the Bohmian and the algebraic…

A framework of nonequilibrium statistical mechanics. I. Role and type of fluctuations
Hans Christian Öttinger, Mark A. Peletier, Alberto Montefusco
Understanding the fluctuations by which phenomenological evolution equations with thermodynamic structure can be enhanced is the key to a general framework of nonequilibrium statis…

Hamiltonian formulation of a class of constrained fourth-order differential equations in the Ostrogradsky framework
Hans Christian Öttinger
We consider a class of Lagrangians that depend not only on some configurational variables and their first time derivatives, but also on second time derivatives, thereby leading to…
