Efficient simulation of infinite tree tensor network states on the Bethe lattice
Wei Li, Jan von Delft, Tao Xiang
We show that the simple update approach proposed by Jiang et. al. [H.C. Jiang, Z.Y. Weng, and T. Xiang, Phys. Rev. Lett. 101, 090603 (2008)] is an efficient and accurate method for…
SU(3) Anderson impurity model: A numerical renormalization group approach exploiting non-Abelian symmetries
Catalin Pascu Moca, Arne Alex, Jan von Delft +1
We show how the density-matrix numerical renormalization group (DM-NRG) method can be used in combination with non-Abelian symmetries such as SU(N), where the decomposition of the…
Full density matrix numerical renormalization group calculation of impurity susceptibility and specific heat of the Anderson impurity model
L. Merker, A. Weichselbaum, T. A. Costi
Recent developments in the numerical renormalization group (NRG) allow the construction of the full density matrix (FDM) of quantum impurity models (see A. Weichselbaum and J. von…
Hybrid NRG-DMRG approach to real-time dynamics of quantum impurity systems
Fabian Guettge, Frithjof B. Anders, Ulrich Schollwoeck +2
A hybrid approach to nonequilibrium dynamics of quantum impurity systems is presented. The numerical renormalization group serves as a means to generate a suitable low-energy Hamil…
Parametric instability in periodically driven Luttinger liquids
Marin Bukov, Markus Heyl
We analyze the properties of a Luttinger liquid under the influence of a periodic driving of the interaction strength. Irrespective of the details the driven system develops an ins…
Lanczos algorithm with Matrix Product States for dynamical correlation functions
P. E. Dargel, A. Wöllert, A. Honecker +3
The density-matrix renormalization group (DMRG) algorithm can be adapted to the calculation of dynamical correlation functions in various ways which all represent compromises betwe…
