SUMMARY:"Bose Condensation" in Strongly Spin-Orbit Coupled Dimer Magnets
DESCRIPTION:Featuring Michael Flynn\, UCDavis\n\nPart of the Biophysics/Con
	densed Matter Seminar Series.\n\nIn recent decades\, frustrated magnetic sy
	stems have been studied as hosts of some of the most exotic strongly correl
	ated phases of matter ever discovered. Among these systems\, quantum dimer 
	magnets offer an environment in which to study Bose Einstein Condensation t
	ransitions\, where an external magnetic field plays the role of the chemica
	l potential. Recently\, the dimer compound Ytterbium Silicate (Yb Si O ) wa
	s found to exhibit violations of the now-paradigmatic dimer magnet phase di
	agram. In particular\, evidence was obtained for an unexpected field-induce
	d phase transition to a state with an unknown order. With a variety of tech
	niques\, we will show that this empirical data is captured by a simple mode
	l of dimerized spins which weakly breaks lattice inversion symmetry. We wil
	l offer predictions for the order underlying the "mystery" phase\, and natu
	ral empirical tests of these predictions will be discussed. Finally\, we wi
	ll make perturbative connections between this model and XYZ Heisenberg mode
	ls; alternative formulations of this physics include models of fermions in 
	one dimension\, and hard-core bosons in higher dimensions.\n\nJoin on Zoom:
