  • Entropy of fermionic models on highly frustrated lattices 
    Honecker, A.; Richter, J. (Condensed Matter Physics, 2005)
    Spinless fermions on highly frustrated lattices are characterized by the lowest single-particle band which is completely flat. Concrete realizations are provided by the sawtooth chain and the kagome lattice. For these ...
  • Magnetocaloric effect in quantum spin-s chains 
    Honecker, A.; Wessel, S. (Condensed Matter Physics, 2009)
    We compute the entropy of antiferromagnetic quantum spin-s chains in an external magnetic field using exact diagonalization and Quantum Monte Carlo simulations. The magnetocaloric effect, i. e., temperature variations during ...
  • Universal properties of highly frustrated quantum magnets in strong magnetic fields 
    Derzhko, O.; Richter, J.; Honecker, A.; Schmidt, H.-J. (Физика низких температур, 2007)
    The purpose of the present paper is two-fold. On the one hand, we review some recent studies on the low-temperature strong-field thermodynamic properties of frustrated quantum spin antiferromagnets which admit the so-called ...
