Strongly coupled quantum criticality with a Fermi surface in two dimensions: fractionalization of spin and charge collective modes
Subir Sachdev, Takao Morinari
We describe two dimensional models with a metallic Fermi surface which display quantum phase transitions controlled by strongly interacting critical field theories below their uppe…

Reexamination of d-wave superconductivity in the two-dimensional Hubbard model
Takao Morinari
We reexamine the possibility of d-wave superconductivity in the hole-doped two-dimensional Hubbard model. In terms of the gauge field description of the spin fluctuations, we show…

The role of imaginary vector potential in composite fermion pairing theory
Takao Morinari
We show that the imaginary vector potential causes a pair-breaking effect in the composite fermion theory, and discuss its irrelevance in the pairing state. The Hamiltonian for pai…
