Magnetization process of a quasi-two-dimensional quantum magnet: Two-step symmetry restoration and dimensional reduction
Anneke Reinold, Lucas Berger, Marcin Raczkowski +9
We report on a comprehensive thermodynamic study of a quasi-two-dimensional (quasi-2D) quantum magnet Cu(OH)Br which in the 2D layer can be viewed as strongly coupled alter…
Alteration of Topology in Quantum Phase Transitions via Symmetry Enrichment
Gabriel Rein, Marcin Raczkowski, Zhenjiu Wang +2
Topology plays a cardinal role in explaining phases and quantum phase transitions beyond the Landau-Ginzburg-Wilson paradigm. In this study, we formulate a set of models of Dirac f…
SU() Kondo-Heisenberg chain: Phase diagram, Ising criticality, and the coexistence of heavy quasiparticles and valence bond solid order
Marcin Raczkowski, Fakher F. Assaad
We map out the ground state phase diagram of a one-dimensional SU() Kondo-Heisenberg lattice model at half filling and in the fully antisymmetric self-adjoint representation as…
