Speaker: *Ganapathy Baskaran *(Matscience, IITMadras, India & Perimeter
Institute, Waterloo, Canada)
Title: *Emergent Quantum Spin Liquids in Lower Dimensional Ferromagnetic
Spin Systems
*
Abstracts:
Quantum Fluctuations remove long range Ferromagnetic order in 1D
spin-1/2 XX Ferromagnetic Chains: a free Fermi sea of neutral
Jordan-Wigner Fermions emerge. A small Ising Ferromagnetic anisotropy in
XXZ chain favors pairing of JW Fermions. It results in a novel `Spin
Superfluid' phase (Baskaran, 1982, ICTP Internal Report; IC/82/126), via
Fermion pair condensation (triplet RVB phase, in modern parlance) in
weakly coupled system of Ferromagnetic XXZ Chains. We discuss emergent
quantum spin liquids in systems with ferromagnetic anisotropy (eg.,
Konig, Komijani and Coleman, PRB 2022) and contrast it with currently
popular quantum spin liquids in frustrated antiferromagnetic systems.
