Universality in the Photophysics of pi-Conjugated Polymers and Single-Walled Carbon Nanotubes

Sumit Mazumdar, Zhendong Wang, Hongbo Zhao

We describe both pi-conjugated polymers and semiconducting single-walled carbon nanotubes because of the remarkable similarities in their behavior under photoexcitation. The common…

Photophysics of charge-transfer excitons in thin films of π-conjugated polymers

Zhendong Wang, Sumit Mazumdar, Alok Shukla

We develop a theory of the electronic structure and photophysics of interacting chains of π- conjugated polymers to understand the differences between solutions and films. While ph…

Electron-electron interaction effects on the photophysics of metallic single-walled carbon nanotubes

Zhendong Wang, Demetra Psiachos, Roberto F. Badilla +1

Single-walled carbon nanotubes are strongly correlated systems with large Coulomb repulsion between two electrons occupying the same orbital. Within a molecular Hamiltonian a…

Absence of superconductivity in the half-filled band Hubbard model on the anisotropic triangular lattice

R. T. Clay, H. Li, S. Mazumdar

We report exact calculations of magnetic and superconducting pair-pair correlations for the half-filled band Hubbard model on an anisotropic triangular lattice. Our results for the…

Quantum critical transition from charge-ordered to superconducting state in the triangular lattice negative-U extended Hubbard model

S. Mazumdar, R. T. Clay

We demonstrate a robust frustration-driven charge-order to superconductivity transition in the half-filled negative-U extended Hubbard model. Superconductivity extends over a broad…
