Using a fermionic "triplon" representation for spins, we study the phase diagram within mean-field theory. In addition to a fully gapped spin-liquid ground state, we find a state where one gapless triplon mode with a Fermi surface coexists with d+id topological pairing of the other triplons. Despite the existence of a Fermi surface, this ground state has fully gapped bulk spin excitations. Such a state has linear in-temperature specific heat and constant in-plane spin susceptibility, with an unusually high Wilson ratio.","lang":"eng"}],"_id":"967","extern":1,"quality_controlled":0,"date_updated":"2021-01-12T08:22:18Z","type":"journal_article","publist_id":"6432","status":"public","month":"11","publication":"Physical Review B - Condensed Matter and Materials Physics","year":"2011","main_file_link":[{"url":"https://arxiv.org/abs/1108.3070","open_access":"1"}],"volume":84,"citation":{"apa":"Serbyn, M., Senthil, T., & Lee, P.
