A quantum spin Hall insulating state that arises from spontaneous symmetry breaking has remarkable properties: skyrmion textures of the SO(3) order parameter carry charge 2e. Doping this state of matter opens a new route to superconductivity via the condensation of skyrmions. We define a model amenable to large-scale negative sign free quantum Monte Carlo simulations that allows us to study this transition. Our results support a direct and continuous doping-induced transition between the… 
Charged skyrmions and topological origin of superconductivity in magic-angle graphene
TLDR
It is shown how topological textures can mitigate Coulomb repulsion and provide a previously unexplored route to superconductivity.

Superconductivity from the condensation of topological defects in a quantum spin-Hall insulator
TLDR
A model of interacting Dirac fermions where a QSH state is dynamically generated where a monopole-free deconfined quantum critical point is offered, making it more amenable to detailed numerical studies.
The Resonating Valence Bond State in La2CuO4 and Superconductivity
The oxide superconductors, particularly those recently discovered that are based on La2CuO4, have a set of peculiarities that suggest a common, unique mechanism: they tend in every case to occur near
Deconfined Quantum Critical Points
TLDR
It is shown that near second-order quantum phase transitions, subtle quantum interference effects can invalidate this paradigm for quantum criticality, and a theory of quantum critical points in a variety of experimentally relevant two-dimensional antiferromagnets is presented.
A Novel Technique for the Simulation of Interacting Fermion Systems
A new method for the simulation of ground-state properties of interacting fermions is introduced. A trial wave function, which is assumed to be a Slater determinant, is propagated to large imaginary
Np − 1 is the thermal average of particle numbers, with the Np and the Np −2 sector tuned to have the same ground-state energy at the chemical potential defined in Eq
    Since we are working in the canonical ensemble, the smallest doping is set by 2/(2L 2 )
      The fact that there is no additional phase factor in the above summations comes from the known ordering wave vector k = Γ
        An intermediate metallic state would be unstable to pairing and we have excluded fine-tuning
