Tangent space Krylov computation of real-frequency spectral functions: Influence of density-assisted hopping on 2D Mott physics
Oleksandra Kovalska, Jan von Delft, Andreas Gleis
We present a tangent-space Krylov (TaSK) method for efficient computation of zero-temperature real-frequency spectral functions on top of ground state (GS) matrix product states (M…
Oscillate and Renormalize: Fast Phonons Reshape the Kondo Effect in Flat Band Systems
Liam L. H. Lau, Andreas Gleis, Daniel Kaplan +2
We examine the interplay between electron correlations and phonons in an Anderson-Holstein impurity model with an Einstein phonon. When the phonons are slow compared to charge fluc…
Reply to comment on "Controlled bond expansion for Density Matrix Renormalization Group ground state search at single-site costs"
Andreas Gleis, Jheng-Wei Li, Jan von Delft
We reply to McCulloch and Osborne's recent comment on our manuscript (Phys. Rev. Lett. 130, 246402 (2023)) on controlled bond expansion (CBE) for density matrix renormalization gro…
