Quantum theory of structured monochromatic light
Alexander Punnoose, Jiufeng J. Tu
Applications that envisage utilizing the orbital angular momentum (OAM) at the single photon level assume that the OAM degrees of freedom that the photons inherit from the classica…
Temperature-induced spontaneous time-reversal symmetry breaking on the honeycomb lattice
Wei Liu, Alexander Punnoose
Phase transitions involving spontaneous time-reversal symmetry breaking are studied on the honeycomb lattice at finite hole-doping with next-nearest-neighbor repulsion. We derive a…
Excitonic instabilities and spontaneous time-reversal symmetry breaking on the honeycomb lattice
Wei Liu, Alexander Punnoose
We elucidate the close relationship between spontaneous time-reversal symmetry breaking and the physics of excitonic instabilities in strongly correlated multiband systems. The und…
Optical properties of the iron-arsenic superconductor BaFe1.85Co0.15As2
J. J. Tu, J. Li, W. Liu +7
The transport and complex optical properties of the electron-doped iron-arsenic superconductor BaFe1.85Co0.15As2 with Tc = 25 K have been examined in the Fe-As planes above and bel…
Penultimate fate of a dirty-Fermi-liquid
Alexander Punnoose, Alexander M. Finkel'stein
The theory of the dirty-Fermi-liquid which details the destruction of the Fermi-liquid phase up to and including the quantum critical point separating the metallic from the insulat…
Renormalization group study of a two-valley system with spin-splitting
Alexander Punnoose
Renormalization group equations in a two-valley system with valley-splitting and intervalley scattering are derived in the presence of spin-splitting induced by a parallel magnetic…
