Einstein's Basement: A new sector for hypothetical particles — •Fritz Riehle and Sebastian Ulbricht — Physikalisch-Technische Bundesanstalt Braunschweig

The extremely fruitful concept of an avoided crossing in mechanical, optical, electrical science and in quantum mechanics of molecules, quantum chemistry and others rises the question for a supplement of the relativistic physics of particles. In this new sector - dubbed as Einstein*s basement - new quasi particles with novel kinematic properties occur [1]. The new particles cannot be treated as a sector of the standard model of particles. We calculate the kinematics between the new particles and regular particles under Newtonian gravity which under special conditions can lead to repulsion of the basement particles and a modified interaction with regular matter.
