Existence of Ground State Eigenvalues for the Spin-Boson Model with Critical Infrared Divergence and Multiscale Analysis
Volker Bach, Miguel Ballesteros, Martin Könenberg +1
A two-level atom coupled to the radiation field is studied. First principles in physics suggest that the coupling function, representing the interaction between the atom and the ra…
Indirect retrieval of information and the emergence of facts in quantum mechanics
Miguel Ballesteros, Martin Fraas, Jürg Fröhlich +1
Long sequences of successive direct (projective) measurements or observations of a few "uninteresting" physical quantities of a quantum system may reveal indirect, but precise and…
Existence and Construction of Resonances for Atoms Coupled to the Quantized Radiation Field
Volker Bach, Miguel Ballesteros, Alessandro Pizzo
For a nonrelativistic atom, which is minimally coupled to the quantized radiation field, resonances emerging from excited atomic eigenstates are constructed by an iteration scheme…
