Finite-temperature Green's function cluster expansion from thermofield doubles: Breakdown of the polaron picture
M. R. Carbone, S. Fomichev, B. Kloss +4
We introduce a method, numerically exact in principle, for computing the momentum- and frequency-resolved single-particle Green's function of a polaron at finite temperature. The m…
Self-consistent GW theory for superconductivity in SrTiO3 models
Zhi-Hao Cui, John Sous, Andrew J. Millis +1
Superconductivity in doped SrTiO occurs over a wide range of carrier densities, including those for which the Fermi energy is below the polar longitudinal optical phonon scale.…
Correlation Functions From Tensor Network Influence Functionals: The Case of the Spin-Boson Model
Haimi Nguyen, Nathan Ng, Lachlan P. Lindoy +4
We investigate the application of matrix product state (MPS) representations of the influence functionals (IF) for the calculation of real-time equilibrium correlation functions in…
Downfolding from Ab Initio to Interacting Model Hamiltonians: Comprehensive Analysis and Benchmarking of the DFT+cRPA Approach
Yueqing Chang, Erik G. C. P. van Loon, Brandon Eskridge +8
Model Hamiltonians are regularly derived from first-principles data to describe correlated matter. However, the standard methods for this contain a number of largely unexplored app…
Length-scales of interfacial coupling between metal-insulator phases in oxides
Claribel Domínguez, Alexandru B. Georgescu, Bernat Mundet +10
Controlling phase transitions in transition metal oxides remains a central feature of both technological and fundamental scientific relevance. A well-known example is the metal-ins…
Evidence of an improper displacive phase transition in CdReO via time-resolved coherent phonon spectroscopy
J. W. Harter, D. M. Kennes, H. Chu +6
We have used a combination of ultrafast coherent phonon spectroscopy, ultrafast thermometry, and time-dependent Landau theory to study the inversion symmetry breaking phase transit…
