Spin functional renormalization group for the quantum Heisenberg model
Dmytro Tarasevych, Andreas Rückriegel, Savio Keupert +2
We use our recently developed functional renormalization group (FRG) approach for quantum spin systems to investigate the phase diagram of the frustrated quantum…
Spin functional renormalization group for dimerized quantum spin systems
Andreas Rückriegel, Jonas Arnold, Raphael Goll +1
We investigate dimerized quantum spin systems using the spin functional renormalization group approach proposed by Krieg and Kopietz [Phys. Rev. B 99, 060403(R) (2019)] which direc…
Phonon renormalization and Pomeranchuk instability in the Holstein model
Niklas Cichutek, Max Hansen, Peter Kopietz
The Holstein model with dispersionless Einstein phonons is one of the simplest models describing electron-phonon interactions in condensed matter. A naive extrapolation of perturba…
