Tree tensor-network real-time multiorbital impurity solver: Spin-orbit coupling and correlation functions in SrRuO
X. Cao, Y. Lu, P. Hansmann +1
We present a tree tensor-network impurity solver suited for general multiorbital systems. The network is constructed to efficiently capture the entanglement structure and symmetry…
Topological second-order spin-3/2 liquids with hinge Fermi arcs
Y. X. Zhao, Y. Lu, Shengyuan A. Yang
We present an exactly solvable spin-3/2 model defined on a pentacoordinated three-dimensional graphite lattice, which realizes a novel quantum spin liquid with second-order topolog…
Long-range charge density wave proximity effect at cuprate-manganate interfaces
A. Frano, S. Blanco-Canosa, E. Schierle +13
The interplay between charge density waves (CDWs) and high-temperature superconductivity is currently under intense investigation. Experimental research on this issue is difficult…
Quantitative determination of bond order and lattice distortions in nickel oxide heterostructures by resonant x-ray scattering
Y. Lu, A. Frano, M. Bluschke +10
We present a combined study of Ni -edge resonant x-ray scattering and density functional calculations to probe and distinguish electronically driven ordering and lattice distort…
Bands, resonances, edge singularities and excitons in core level spectroscopy investigated within the dynamical mean field theory
M. W. Haverkort, G. Sangiovanni, P. Hansmann +3
Using a recently developed impurity solver we exemplify how dynamical mean field theory captures band excitations, resonances, edge singularities and excitons in core level x-ray a…
Efficient real frequency solver for dynamical mean field theory
Y. Lu, M. Höppner, O. Gunnarsson +1
We here present how a self-consistent solution of the dynamical mean field theory equations can be obtained using exact diagonalization of an Anderson impurity model with accuracie…
