Transient quantum isolation and critical behavior in the magnetization dynamics of half-metallic manganites
Tommaso Pincelli, Riccardo Cucini, Adriano Verna +22
We combine time resolved pump-probe Magneto-Optical Kerr Effect and Photoelectron Spectroscopy experiments supported by theoretical analysis to determine the relaxation dynamics of…
Orbitally selective breakdown of Fermi liquid quasiparticles in CaSrRuO
Denys Sutter, Minjae Kim, Christian Matt +16
We present a comprehensive angle-resolved photoemission spectroscopy study of CaSrRuO. Four distinct bands are revealed and along the Ru-O bond direction their…
Spectral functions of SrIrO: theory versus experiment
Benjamin Lenz, Cyril Martins, Silke Biermann
The spin-orbit Mott insulator SrIrO has attracted a lot of interest in recent years from theory and experiment due to its close connection to isostructural high-tempera…
Hall coefficient signals orbital differentiation in the Hund's metal SrRuO
Manuel Zingl, Jernej Mravlje, Markus Aichhorn +2
The Hall coefficient of SrRuO exhibits a non-monotonic temperature dependence with two sign reversals. We show that this puzzling behavior is the signature of two cro…
Diagonal Padé Approximant of the one-body Green's function, a study on Hubbard rings
Walter Tarantino, Stefano Di Sabatino
Padé approximants to the many-body Green's function can be built by rearranging terms of its perturbative expansion. The hypothesis that the best use of a finite number of terms of…
Real-Time Ramsey Interferometry in Fractional Quantum Hall States
Tal Goren, Karyn Le Hur
We study the time-dependent dynamical phase of fractional quasiparticles in quantum Hall states using Ramsey interferometry. A Ramsey two-pulse voltage modulation generates an inte…
