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…
