Bilocal quantum criticality
Harley D. Scammell, Mathias S. Scheurer, Subir Sachdev
We consider 2+1 dimensional conformal gauge theories coupled to additional degrees of freedom which induce a spatially local but long-range in time interaction between…
Phases of SU(2) gauge theory with multiple adjoint Higgs fields in 2+1 dimensions
Harley D. Scammell, Kartik Patekar, Mathias S. Scheurer +1
A recent work (arXiv:1811.04930) proposed a SU(2) gauge theory for optimal doping criticality in the cuprate superconductors. The theory contains Higgs fields transforming un…
Artificial Graphene: Unconventional Superconductivity in a Honeycomb Superlattice
Tommy Li, Julian Ingham, Harley D. Scammell
Artificial lattices have served as a platform to study the physics of unconventional superconductivity. We study semiconductor artificial graphene -- a honeycomb superlattice impos…
Bose-Einstein condensation of deconfined spinons in two dimensions
Adam Iaizzi, Harley D Scammell, Oleg P Sushkov +1
The transition between the Néel antiferromagnet and the valence-bond solid state in two dimensions has become a paradigmatic example of deconfined quantum criticality, a non-Landau…
Gauge theory for the cuprates near optimal doping
Subir Sachdev, Harley D. Scammell, Mathias S. Scheurer +1
We describe the phase diagram of a 2+1 dimensional SU(2) gauge theory of fluctuating incommensurate spin density waves for the hole-doped cuprates. Our primary assumption is that a…
Tuning the topological insulator states of artificial graphene
H. D. Scammell, O. P. Sushkov
We develop a robust, non-perturbative approach to study the band structure of artificial graphene. Artificial graphene, as considered here, is generated by imposing a superlattice…
