Symmetry-broken perturbation theory to large orders in antiferromagnetic phases
R. Garioud, F. Šimkovic, R. Rossi +4
We introduce a spin-symmetry-broken extension of the connected determinant algorithm [Phys. Rev. Lett. 119, 045701 (2017)]. The resulting systematic perturbative expansions around…
High-order expansion around BCS theory
G. Spada, R. Rossi, F. Simkovic +4
We demonstrate that summation of connected diagrams to high order starting from a BCS hamiltonian is a viable generic unbiased approach for strongly correlated fermions in supercon…
Pseudogap, van Hove Singularity, Maximum in Entropy and Specific Heat for Hole-Doped Mott Insulators
A. Reymbaut, S. Bergeron, R. Garioud +4
The first indication of a pseudogap in cuprates came from a sudden decrease of NMR Knight shift at a doping-dependent temperature . Since then, experiments have found phase…
Near-infrared to visible upconversion imaging using a broadband pump laser
Romain Demur, Renaud Garioud, Arnaud Grisard +5
We present an upconversion imaging experiment from the near-infrared to the visible spectrum. Using a dedicated broadband pump laser to increase the number of resolved elements con…
