Correlation-driven phonon renormalisation and the equation of state of -cerium
Yao Wei, Siyu Chen, Evgeny Plekhanov +3
We investigate the thermodynamic properties of elemental cerium by assessing the crucial role of phonon free energy within the framework of dynamical mean-field theory (DMFT). Whil…
Ground State Properties of the Doped Kitaev-Heisenberg Chain: Topological Superconducting and Mott Insulating Phases Driven by Magnetic Frustration
Cliò Efthimia Agrapidis, Satoshi Nishimoto
We study the hole-doped Kitaev-Heisenberg chain using the density-matrix renormalization group. In the Kitaev-only limit, the bond-directional exchange itself promotes pairing, fav…
Interface Spin-orbit Coupling Induced Room-temperature Ferromagnetic Insulator
Yuhao Hong, Shilin Hu, Ziyue Shen +10
Fabricating room-temperature ferromagnetic insulators, which are crucial candidates for next-generation dissipation-free quantum and spintronic devices, remains a significant chall…
Correlation-driven origin of shallow electron pocket in CoTaS revealed by ARPES and cluster perturbation theory
Wojciech Sas, Yuki Utsumi Boucher, Seyed Ashkan Moghadam Ziabari +11
We investigate the electronic structure and Fermi surface of CoTaS using angle-resolved photoemission spectroscopy (ARPES) combined with theoretical modeling beyond sta…
Non-perturbative effects of short-range spatial correlations at the two-particle level
Michael Meixner, Matthias Reitner, Thomas Schäfer +1
By means of cellular dynamical mean-field theory (CDMFT) we study how short-range correlations drive the breakdown of the self-consistent perturbation theory in two-dimensional sys…
Functional renormalization with interaction flows: A single-boson exchange perspective and application to electron-phonon systems
Aiman Al-Eryani, Marcel Gievers, Kilian Fraboulet
The functional renormalization group (fRG) is acknowledged as a powerful tool in quantum many-body physics and beyond. On the technical side, conventional implementations of the fR…
