Nonequilibrium, spatio-temporal formation of the Kondo screening-cloud on a lattice
Martin Nuss, Martin Ganahl, Enrico Arrigoni +2
We study the nonequilibrium formation of a spin screening cloud that accompanies the quenching of a local magnetic moment immersed in a Fermi sea at zero temperature. Based on high…
Efficient DMFT impurity solver using real-time dynamics with Matrix Product States
Martin Ganahl, Markus Aichhorn, Patrik Thunström +3
We propose to calculate spectral functions of quantum impurity models using the Time Evolving Block Decimation (TEBD) for Matrix Product States. The resolution of the spectral func…
Chebyshev expansion for Impurity Models using Matrix Product States
Martin Ganahl, Patrik Thunström, Frank Verstraete +2
We improve a recently developed expansion technique for calculating real frequency spectral functions of any one-dimensional model with short-range interactions, by postprocessing…
