One-Boson Scattering Processes in the Massless Spin-Boson Model -- A Non-Perturbative Formula
Miguel Ballesteros, Dirk-André Deckert, Felix Hänle
In scattering experiments, physicists observe so-called resonances as peaks at certain energy values in the measured scattering cross sections per solid angle. These peaks are usua…

Conditionally Free Reduced Products of Hilbert Spaces
Octavio Arizmendi, Miguel Ballesteros, Francisco Torres-Ayala
We present a product of pairs of pointed Hilbert spaces that, in the context of Bozėjko, Leinert and Speicher's theory of conditionally free probability, plays the role of the redu…
