Electronic Density of States of a Quantum Spin Liquid with Spinon Fermi Surface. II. Zeeman Magnetic Field Effects
Wen-Yu He, Patrick A. Lee
The Zeeman effect lowers the energy of electrons with spin states which are anti-parallel to the applied magnetic field but lifts that of spin parallel states. In quantum spin liqu…

Electronic Density of States of a Quantum Spin Liquid with Spinon Fermi Surface. I. Orbital Magnetic Field Effects
Wen-Yu He, Patrick. A. Lee
Quantum spin liquid (QSL) with spinon Fermi surface is an exotic insulator that hosts neutral Fermi surfaces inside the gap. In an external magnetic field, it has been pointed out…

Magnetic Impurity as a Local Probe of the U(1) Quantum Spin Liquid with Spinon Fermi Surface
Wen-Yu He, Patrick. A. Lee
We solve the problem of a magnetic impurity coupled to a U(1) quantum spin liquid with spinon Fermi surface and compute the impurity spectral function. Using the slave rotor mean f…
