Mottness on a triangular lattice
Dimitrios Galanakis, Tudor Stanescu, Philip Phillips
We study the physics on the paramagnetic side of the phase diagram of the cobaltates, , with an implementation of cellular dynamical mean field theory (CDMFT) with t…
Effective masses in a strongly anisotropic Fermi liquid
Tudor D. Stanescu, Victor Galitski, H. D. Drew
Motivated by the recent experimental observation of quantum oscillations in the underdoped cuprates, we study the cyclotron and infrared Hall effective masses in an anisotropic Fer…
Nodal/Antinodal Dichotomy and the Two Gaps of a Superconducting Doped Mott Insulator
M. Civelli, M. Capone, A. Georges +4
We study the superconducting state of the hole-doped two-dimensional Hubbard model using Cellular Dynamical Mean Field Theory, with the Lanczos method as impurity solver. In the un…
Much Ado about Zeros: The Luttinger Surface and Mottness
Tudor D. Stanescu, Philip W. Phillips, Ting-Pong Choy
We prove that the Mott insulating state is characterized by a divergence of the electron self energy at well-defined values of momenta in the first Brillouin zone. When particle-ho…
Fermi arcs and the hidden zeros of the Green's function in the pseudogap state
Tudor D. Stanescu, Gabriel Kotliar
We investigate the low energy properties of a correlated metal in the proximity of a Mott insulator within the Hubbard model in two dimensions. We introduce a new version of the Ce…
Strong Coupling Theory for Interacting Lattice Models
Tudor D. Stanescu, Gabriel Kotliar
We develop a strong coupling approach for a general lattice problem. We argue that this strong coupling perspective represents the natural framework for a generalization of the dyn…
