Optical and DC conductivity of the two-dimensional Hubbard model in the pseudogap regime and across the antiferromagnetic quantum critical point, including vertex corrections
Dominic Bergeron, Vasyl Hankevych, Bumsoo Kyung +1
The conductivity of the two-dimensional Hubbard model is particularly relevant for high-temperature superconductors. Vertex corrections are expected to be important because of stro…
Pairing dynamics in strongly correlated superconductivity
B. Kyung, D. Sénéchal, A. -M. S. Tremblay
Confirmation of the phononic origin of Cooper pair formation in superconductors came with the demonstration that the interaction was retarded and that the corresponding energy scal…
First order Mott transition at zero temperature in two dimensions: Variational plaquette study
Matthias Balzer, Bumsoo Kyung, David Sénéchal +2
The nature of the metal-insulator Mott transition at zero temperature has been discussed for a number of years. Whether it occurs through a quantum critical point or through a firs…
Conditions for magnetically induced singlet d-wave superconductivity on the square lattice
S. R. Hassan, B. Davoudi, B. Kyung +1
It is expected that at weak to intermediate coupling, d-wave superconductivity can be induced by antiferromagnetic fluctuations. However, one needs to clarify the role of Fermi sur…
Electronic Properties of the Hubbard Model on a Frustrated Triangular Lattice
Bumsoo Kyung
We study novel electronic properties of the Hubbard model on a triangular lattice using the cellular dynamical mean-field theory. The interplay of strong geometric frustration and…
Mott Transition, Antiferromagnetism, and d-wave Superconductivity in Two-Dimensional Organic Conductors
B. Kyung, A. -M. S. Tremblay
We study the Mott transition, antiferromagnetism and superconductivity in layered organic conductors using Cellular Dynamical Mean Field Theory for the frustrated Hubbard model. A…
