Multi-Time Version of the Landau-Peierls Formulation of Quantum Electrodynamics
Matthias Lienert, Roderich Tumulka
Landau and Peierls wrote down the Hamiltonian of a simplified version of quantum electrodynamics in the particle-position representation. We present a multi-time version of their S…
Properties of non-cryogenic DTs and their relevance for fusion
Hartmut Ruhl, Christian Bild, Ondrej Pego Jaura +4
In inertial confinement fusion, pure deuterium-tritium (DT) is usually used as a fusion fuel. In their paper \cite{gus2011effect}, Guskov et al. instead propose using low-Z compoun…
Probability conservation for multi-time integral equations
Matthias Lienert
In relativistic quantum theory, one sometimes considers integral equations for a wave function depending on two space-time points for two particles. A serious issue wi…
Singular light cone interactions of scalar particles in 1+3 dimensions
Matthias Lienert, Markus Nöth
Here we consider an integral equation describing a fixed number of scalar particles which interact not through boson exchange but directly along light cones, similarly as in bound…
A Lorentz-Covariant Interacting Electron-Photon System in One Space Dimension
Michael K. -H. Kiessling, Matthias Lienert, A. Shadi Tahvildar-Zadeh
A Lorenz-covariant system of wave equations is formulated for a quantum-mechanical two-body system in one space dimension, comprised of one electron and one photon. Manifest Lorent…
Existence of relativistic dynamics for two directly interacting Dirac particles in 1+3 dimensions
Matthias Lienert, Markus Nöth
Here we prove the existence and uniqueness of solutions of a class of integral equations describing two Dirac particles in 1+3 dimensions with direct interactions. This class of in…
