Gapped commensurate antiferromagnetic response in a strongly underdoped model cuprate superconductor
Zachary W. Anderson, Yang Tang, Vikram Nagarajan +13
It is a distinct possibility that spin fluctuations are the pairing interactions in a wide range of unconventional superconductors. In the case of the high-transition-temperature (…
Spin dynamics in itinerant antiferromagnet SrCrAs
Zhenhua Ning, Pinaki Das, Y. Lee +6
SrCrAs is an itinerant antiferromagnet in the same structural family as the SrFeAs high-temperature superconductors. We report our calculations of exchange-coupling…
Incipient nematicity from electron flat bands in a kagome metal
Nathan Drucker, Thanh Nguyen, Manasi Mandal +16
Engineering new quantum phases requires fine tuning of the electronic, orbital, spin, and lattice degrees of freedom. To this end, the kagome lattice with flat bands has garnered g…
Magnetic interactions and excitations in SrMnSb
Zhenhua Ning, Bing Li, Weilun Tang +7
The magnetic interactions in the antiferromagnetic (AFM) Dirac semimetal candidate SrMnSb are investigated using \textit{ab initio} linear response theory and inelastic neutron…
