Phases of (2+1)D SO(5) non-linear sigma model with a topological term on a sphere: multicritical point and disorder phase
Bin-Bin Chen, Xu Zhang, Yuxuan Wang +2
Novel critical phenomena beyond the Landau-Ginzburg-Wilson paradigm have been long sought after. Among many candidate scenarios, the deconfined quantum critical point (DQCP) consti…
Quantum chaos and phase transition in the Yukawa-SYK model
Andrew Davis, Yuxuan Wang
We analyze the quantum chaotic behavior of the Yukawa-SYK model as a function of filling and temperature, which describes random Yukawa interactions between complex fermions an…
Solvable model for a charge- superconductor
Nikolay V. Gnezdilov, Yuxuan Wang
A charge- superconductor forms due to the condensation of quartets of electrons. While in previous works the mechanism for the formation of charge- superconductivity has be…
SU(4) symmetry in twisted bilayer graphene - an itinerant perspective
Dmitry V. Chichinadze, Laura Classen, Yuxuan Wang +1
We study symmetry-broken phases in twisted bilayer graphene at small filling above charge neutrality and at Van Hove filling. We argue that the Landau functionals for the particle-…
The dynamical exponent of a quantum critical itinerant ferromagnet: a Monte Carlo study
Yuzhi Liu, Weilun Jiang, Avraham Klein +4
We consider the effect of the coupling between 2D quantum rotors near an XY ferromagnetic quantum critical point and spins of itinerant fermions. We analyze how this coupling affec…
Monte Carlo study of the pseudogap and superconductivity emerging from quantum magnetic fluctuations
Weilun Jiang, Yuzhi Liu, Avraham Klein +4
The origin of the pseudogap behavior, found in many high- superconductors, remains one of the greatest puzzles in condensed matter physics. One possible mechanism is fermionic…
