Susceptibility of a spinon Fermi surface coupled to a U(1) gauge field
Cody P. Nave, Sung-Sik Lee, Patrick A. Lee
We study the theory of a U(1) gauge field coupled to a spinon Fermi surface. Recently this model has been proposed as a possible description of the organic compound $κ-(BEDT-TTF)_2…
Emergence of supersymmetry at a critical point of a lattice model
Sung-Sik Lee
Supersymmetry is a symmetry between a boson and a fermion. Although there is no apparent supersymmetry in nature, its mathematical consistency and appealing property have led many…
Emergence of gravity from interacting simplices
Sung-Sik Lee
We consider a statistical model of interacting 4-simplices fluctuating in an N-dimensional target space. We argue that a gravitational theory may arise as a low energy effective th…
Amperean Pairing Instability in the U(1) Spin Liquid State with Fermi Surface and Application to
Sung-Sik Lee, Patrick A. Lee, T. Senthil
Recent experiments on the organic compound raise the possibility that the system may be described as a quantum spin liquid. Here we propose a pairing s…
Observation of emergent photon in Monte Carlo simulation of exciton condensate
Sung-Sik Lee, Patrick A. Lee
Using Monte Carlo simulation, we studied fractionalized phases in a model of exciton bose condensate and found evidence for an emergent photon in a finite size system. The fraction…
