Using a fermionic &quot;triplon&quot; 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."}],"date_created":"2018-12-11T11:49:27Z","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/1108.3070"}],"date_published":"2011-11-03T00:00:00Z","author":[{"last_name":"Serbyn","first_name":"Maksym","id":"47809E7E-F248-11E8-B48F-1D18A9856A87","full_name":"Maksym Serbyn","orcid":"0000-0002-2399-5827"},{"full_name":"Senthil, Todadri S","last_name":"Senthil","first_name":"Todadri"},{"last_name":"Lee","first_name":"Patrick","full_name":"Lee, Patrick"}],"publication_status":"published","doi":"10.1103/PhysRevB.84.180403","year":"2011"}
