Origin of misleading convergence in self-consistent many-electron theories: Fundamental aspects and practical implications
Herbert EÃl, Matthias Reitner, Evgeny Kozik +1
Self-consistent approaches in many-electron problems typically converge to an unphysical solution in strongly correlated regimes. By deriving the mathematical condition for the sta…
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…
Amplified response of cavity-coupled quantum-critical systems
Shouvik Sur, Yiming Wang, Mounica Mahankali +2
A quantum critical point develops when matter undergoes a continuous transformation between distinct ground states at absolute zero. It hosts pronounced quantum fluctuations, which…
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…
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…
Emergence of a Fluctuating Ground State in Y-kapellasite under Pressure
Dipranjan Chatterjee, Petr Doležal, Federico Abbruciati +17
Y-kapellasite (YCu(OH)Cl), which hosts an original anisotropic kagome sublattice, is a promising candidate for studying elusive and complex correlated physics. I…
