Extended symmetric quantum phase in a honeycomb Heisenberg model with sublattice-selective interactions
Nai Chao Hu, Xing-Yu Zhang, Yuchi He +1
Motivated by two-dimensional bilayer systems we numerically study an anti-ferromagnetic spin- Heisenberg model on the honeycomb lattice with a nearest-neighbour exchange coupl…
Superconductivity from emergent dipolar interactions in a fractionalized Fermi liquid
Mina-Lou Schleith, Arthur Bril, Nick Bultinck
Starting from the spin-fermion model or Hertz-Millis theory describing electrons coupled to anti-ferromagnetic spin fluctuations we develop a theory to describe the transition from…
Quantum Monte Carlo fermion spectroscopy of a non-compact CP model
Xu Zhang, Nick Bultinck
We study a model describing electrons coupled to anti-ferromagnetic spin fluctuations, and consider the situation where hedgehog defects in the order parameter field are suppressed…
Lowering the temperature of two-dimensional fermionic tensor networks with cluster expansions
Sander De Meyer, Atsushi Ueda, Yuchi He +2
Representing the time-evolution operator as a tensor network constitutes a key ingredient in several algorithms for studying quantum lattice systems at finite temperature or in a n…
