Dual parquet scheme for the two-dimensional Hubbard model: modelling low-energy physics of high- cuprates with high momentum resolution
G. V. Astretsov, G. Rohringer, A. N. Rubtsov
We present a new method to treat the two-dimensional (2D) Hubbard model for parameter regimes which are relevant for the physics of the high- superconducting cuprates. Unlike…

Fate of a topological invariant for correlated lattice electrons at finite temperature
A. A. Markov, G. Rohringer, A. N. Rubtsov
Electrons on a two-dimensional (2) lattice which is exposed to a strong uniform magnetic field show intriguing physical phenomena. The spectrum of such systems exhibits a comple…
