Curvature-induced bound states in quantum wires
Tim Bergmann, Benjamin Schwager, Jamal Berakdar
A classical particle under spatial constraints is strictly confined to live on a specific space manifold or path, but this assumption is incompatible with the zero-point fluctuatio…
Parity Violation in Hydrogen and Longitudinal Atomic Beam Spin Echo I
T. Bergmann, T. Gasenzer, M. DeKieviet +2
We discuss the propagation of hydrogen atoms in static electric and magnetic fields in a longitudinal atomic beam spin echo (lABSE) apparatus. There the atoms acquire geometric (Be…
Metastable states, the adiabatic theorem and parity violating geometric phases II
Timo Bergmann, Thomas Gasenzer, Otto Nachtmann
We discuss and calculate parity conserving (PC) and parity violating (PV) geometric phases for the metastable 2S states of hydrogen and deuterium. The atoms are supposed to be subj…
Metastable states, the adiabatic theorem and parity violating geometric phases I
Timo Bergmann, Thomas Gasenzer, Otto Nachtmann
A system of metastable plus unstable states is discussed. The mass matrix governing the time development of the system is supposed to vary slowly with time. The adiabatic limit for…
