Analytic continuation of Green's functions with a neural network
Fakher Assaad, Johanna Erdmenger, Anika Götz +3
An important problem in many-body physics is to reconstruct the spectral density from the imaginary-time domain Green's function. Typically, the imaginary-time Green's function is…
Tuning the order of a deconfined quantum critical point
Anika Götz, Fakher F. Assaad, Natanael C. Costa
We consider a Su-Schrieffer-Heeger model in the assisted hopping limit, where direct electron hopping is subdominant. At fixed electron-phonon coupling and in the absence of Coulom…
Flat band projections: Sign problem mapping for frustrated spin systems
Maksim Ulybyshev, Anika Götz, Fakher Assaad
Projection of the Coulomb potential onto flat bands paves the way to design various interactions in the particle-hole and particle-particle channels. Here we pose the question if w…
Valence-bond solid to antiferromagnet transition in the two-dimensional Su-Schrieffer-Heeger model by Langevin dynamics
Anika Götz, Stefan Beyl, Martin Hohenadler +1
The two-dimensional Su-Schrieffer-Heeger model of electrons coupled to quantum phonons is investigated using Langevin dynamics within the framework of auxiliary-field quantum Monte…
