Photoexcitations in the Hubbard model -- generalized Loschmidt amplitude analysis of impact ionization in small clusters
Clemens Watzenböck, Markus Wallerberger, Laurenz Ruzicka +3
We study photoexcitations in small Hubbard clusters of up to 12 sites, some of which show an increase of the double occupation after the electric field pulse through impact ionizat…
Non-perturbative landscape of the Mott-Hubbard transition: Multiple divergence lines around the critical endpoint
T. Schäfer, S. Ciuchi, M. Wallerberger +5
We analyze the highly non-perturbative regime surrounding the Mott-Hubbard metal-to-insulator transition (MIT) by means of dynamical mean field theory calculations at the two-parti…
Charge exchange and ionisation in N, N, C - H() collisions studied systematically by theoretical approaches
Katharin Igenbergs, Josef Schweinzer, Alexander Veiter +5
The introduction of gases like nitrogen or neon for cooling the edge region of magnetically confined fusion plasmas has triggered a renewed interest in state selective cross sectio…
