Correlations in the Bose & Fermi Hubbard Model
Friedemann Queisser, Konstantin Krutitsky, Patrick Navez +1
We study the Bose-Hubbard and Fermi-Hubbard model in the limit of large coordination numbers Z (i.e., many tunnelling partners). Via a controlled expansion into powers of 1/Z, we e…

Influence of nontrivial backgrounds and decoherence on vacuum decay
Friedemann Queisser
We present new solutions of vacuum decay in non-Minkowski spacetimes. On a de Sitter background, the tunneling between vacuum states with a nonvanishing energy difference has been…
