@article{Rosales2013BrokenDS, title={Broken discrete symmetries in a frustrated honeycomb antiferromagnet}, author={H. D. Rosales and Daniel C. Cabra and Carlos Alberto Lamas and Pierre Pujol and M E Zhitomirsky}, journal={Physical Review B}, year={2013}, volume={87}, pages={104402} }

The search for a quantum spin liquid – an insulatingmagnet with a gapless ground state which breaks neitherlattice nor spin symmetries – has been the focus of manystudies on two-dimensionalfrustrated quantum antiferro-magnets [1–4]. Such systems are assumed to be the maincandidates to describe a rich variety of unconventionalphases, phase transitions and critical points with decon-ﬁned fractional excitations [5–7]. Frustration plays animportant role in classical systems as well. Within… Expand

Focusing on the interplay between charge and spin degrees of freedom in itinerant electron systems, it is shown that itinerant frustration, which is the competition among electron-mediated interactions, plays a central role in stabilizing a variety of topological spin crystals including a skyrmion crystal with unconventional high skyrnion number, meron crystals, and hedgehog crystals.
