Alternative classical Lagrangians for the Standard-Model Extension
João A. A. S. Reis, Marco Schreck, Ronaldo Thibes
The current paper introduces classical, relativistic Lagrangians for point-particle analogs to the field theory description of the Standard-Model Extension (SME) for Lorentz violat…
Vacuum Cherenkov Radiation for Nonminimal Isotropic Lorentz Violation
Albert Yu. Petrov, Marco Schreck, Alexandre R. Vieira
In this work, we study the effects of vacuum Cherenkov radiation caused by nonminimal dimension-5 Lorentz-violating (LV) operators in the fermion sector. Explicitly, we focus on tw…
Lorentz violation and momentum-space geometric phases
Alan Kostelecky, Ralf Lehnert, Marco Schreck +1
Geometric phases can manifest when a relativistic quantum particle moves cyclically along a loop in parameter space. The phase can be affected by the presence of a background field…
Physical interpretation of large Lorentz violation via Weyl semimetals
Alan Kostelecky, Ralf Lehnert, Marco Schreck +1
The physical intepretation of effective field theories of fundamental interactions incorporating large Lorentz violation is a long-standing challenge, known as the concordance prob…
