OMRANI, ALEXANDER RISS, CHRISTOPH KARRASCH, HAN SAE JUNG, RAMIN KHAJEH, DILLON WONG, UCB Physics, KENJI WATANABE, For small enough twist angles θ ≲ 2°, we find weakly Landau damped interband plasmons, that is, collective excitonic modes that exist in the undoped material with an almost constant energy dispersion. This paper provides a study and discussion of earlier as well as novel more efficient schemes for the precise evaluation of finite-temperature response functions of strongly correlated quantum systems in the framework of the time-dependent density matrix renormalization group (tDMRG). Floquet engineering - the idea that a periodically driven non-equilibrium system can effectively emulate the physics … strongly anisotropic crystals 1d system: SrCuO 2 2d system: La 2CuO 4 quantum dots and wires Assistant at the IT Service of the department of physics at FU Berlin 2016 Bachelor of Science at FU Berlin (group of Piet Brouwer) 2016 - 2017 Research assistant at Leibniz Institute for Astrophysics Potsdam (AIP), Germany ... PhD student of Christoph Karrasch, TU Braunschweig, Germany Publications. We introduce a mechanism for light-induced Floquet engineering of the Fermi surface to dynamically tip the balance between competing instabilities in correlated condensed matter systems in the vicinity of a van-Hove singularity. 24 rue Lhomond, 75231 Paris Cedex 05, France We introduce a method to evaluate the steady-state non-equilibrium Keldysh-Schwinger Green's functions for infinite systems subject to both an electric field and a coupling to reservoirs. Department of Physics, University of California, Berkeley, California 94720, USA and Materials Sciences Division, Lawrence Berkeley National Laboratory, Berkeley, California 94720, USA Invented in 1992 by Steve White, the method was very rapidly adapted by the numerical many body methods groups around the globe. It is well understood that this free theory, and even interacting integrable models, can support ballistic transport of conserved quantities including energy. 1 Department of Physics, University of California, Berkeley, Berkeley, California 94720, USA; 2 Dahlem Center for Complex Quantum Systems and Fachbereich Physik, Freie Universität Berlin, 14195 Berlin, Germany; 3 Technische Universität Braunschweig, Institut für Mathematische Physik, Mendelssohnstraße 3, 38106 Braunschweig, Germany National Institute for Materials Science, 1-1 Namiki, Tsukuba, 305-0044, Japan ...

We show that any interacting integrable model possesses a class of initial states for which the leading corrections to ballistic transport are subdiffusive rather than diffusive. Dante M.
