Numerical approach to the modular operator for fermionic systems
Henning Bostelmann, Daniela Cadamuro, Christoph Minz
We numerically approximate the Tomita-Takesaki modular operator for local subalgebras of the 1+1-dimensional massive Majorana field. Our method works at the one-particle level with…

Shock Wave Polarizations and Optical Metrics in the Born and the Born-Infeld Electrodynamics
Christoph Minz, Horst-Heino von Borzeszkowski, Thoralf Chrobok +1
We analyze the behavior of shock waves in nonlinear theories of electrodynamics. For this, by use of generalized Hadamard step functions of increasing order, the electromagnetic po…
