Breakdown of Fermi Liquid Theory in Doped Mott Insulators by Dynamical Spectral Weight Transfer
Philip Phillips, Ting-Pong Choy, Robert G. Leigh
We show that doped Mott insulators exhibit a collective degree of freedom, not made out of the elemental excitations, because the number of single-particle addition states at low e…

Hidden Charge 2e Boson in Doped Mott Insulators: Field Theory of Mottness
Robert G. Leigh, Philip Phillips, Ting-Pong Choy
We construct the low energy theory of a doped Mott insulator, such as the high-temperature superconductors, by explicitly integrating over the degrees of freedom far away from the…
