SUMMARY:Quantum Matters Seminar Series: Quantum Spin Liquids and Criticalit
 y\nin Multipolar Materials
CLASS:PUBLIC
DESCRIPTION:YONG-BAEK KIM: QUANTUM SPIN LIQUIDS AND CRITICALITY IN MULTIPOL
 AR\nMATERIALS\n\nAbstract: Multipolar quantum materials possess local mome
 nts carrying\nhigher-rank quadrupolar or octupolar moments. These higher-r
 ank\nmultipolar moments arise due to strong spin-orbit coupling and local\
 nsymmetry of the crystal-electric-field environment. In magnetic\ninsulato
 rs\, the interaction between multipolar local moments on\nfrustrated latti
 ces may promote novel quantum spin liquids. In heavy\nfermion systems\, th
 e interaction between multipolar local moments and\nconduction electrons m
 ay lead to unusual non-Fermi liquids and quantum\ncriticality. In this tal
 k\, we first discuss a novel quantum spin ice\nstate\, a three-dimensional
  quantum spin liquid with emergent gauge\nfield\, that may have been real
 ized in Ce2Zr2O7 and Ce2Sn2O7\, where\nCe3+ ions carry dipolar-octupolar
  moments. We present a theoretical\nanalysis of possible quantum spin ice 
 states in this system and\ncompare the theoretical results of dynamical sp
 in structure factors\nwith recent neutron scattering experiments. Next\, w
 e present a\ntheoretical model to describe the unusual Kondo effect and qu
 antum\ncriticality in Ce3Pd20Si6\, where Ce3+ moments carry a plethora of
 \ndipolar\, quadrupolar\, and octupolar moments. We show that two\nconsecu
 tive Kondo-destruction-type phase transitions can occur with\nthe correspo
 nding Fermi surface reconstructions. We compare these\nresults with existi
 ng experiments and suggest future ultrasound\nexperiments for the detectio
 n of emergent quantum critical behaviors.
