Spectroscopic Signatures of Spinon Fermi Surface in a Rare-earth Triangular Lattice Spin Liquid
Speaker Prof. Gang Chen, Fudan University
Date 12 April 2018 (Thursday)
Time 16:00 - 17:30
Venue Lecture Theatre H (Lifts 27-28), HKUST

I will talk about our recent theoretical efforts in a spin liquid candidate material YbMgGaO4. YbMgGaO4 has been proposed to be a quantum spin liquid with spinon Fermi surface by us and is probably the first spin-orbit-coupled spin liquid candidate with odd electron fillings. This is consistent with the recent extension of Lieb-Shultz-Mattias theorem to spin-orbit-coupled matter. I will cover our explanation and prediction for the spectroscopic properties of YbMgGaO4 and discuss the experimental results. The broad class of spin-orbit-coupled magnets will also be covered.
