Fast trimers in one-dimensional extended Fermi-Hubbard model
A. Dhar, P. Törmä, J. J. Kinnunen
We consider a one-dimensional two component extended Fermi-Hubbard model with nearest neighbor interactions and mass imbalance between the two species. We study the stability of tr…

A dynamical mean-field theory study of stripe order and d-wave superconductivity in the two-dimensional Hubbard model
Tuomas I. Vanhala, Päivi Törmä
We use cellular dynamical mean-field theory with extended unit cells to study the ground state of the two-dimensional repulsive Hubbard model at finite doping. We calculate the ene…

Wave packet dynamics of Bogoliubov quasiparticles: quantum metric effects
Long Liang, Sebastiano Peotta, Ari Harju +1
We study the dynamics of the Bogoliubov wave packet in superconductors and calculate the supercurrent carried by the wave packet. We discover an anomalous contribution to the super…
