Raman spectra of unfilled and filled carbon nanotubes: Theory
S. Gayen, S. N. Behera, S. M. Bose
The Raman spectra of two G-bands and a radial breathing mode (RBM) of unfilled and filled single-wall semiconducting and metallic carbon nanotubes have been investigated theoretica…
Electronic properties of ordered and disordered linear clusters of atoms and molecules
S N Behera, S Gayen, G V Ravi Prasad +1
The electronic properties of one-dimensional clusters of N atoms or molecules have been studied. The model used is similar to the Kronig-Penney model with the potential offered by…
Theory of the tangential G-band feature in the Raman spectra of metallic carbon nanotubes
S. M. Bose, S. Gayen, S. N. Behera
The tangential G-band in the Raman spectra of a metallic single-wall carbon nanotube shows two peaks: a higher frequency component having the Lorentzian shape and a lower-frequency…
Single hole doped strongly correlated ladder with a static impurity
S. Gayen
We consider a strongly correlated ladder with diagonal hopping and exchange interactions described by type hamiltonian. We study the dynamics of a single hole in this model i…
Exact ground and excited states of a t-J ladder doped with two holes
Indrani Bose, Saurabh Gayen
A two chain ladder model is considered described by the strong coupling Hamiltonian. For the case of two holes moving in a background of antiferromagnetical…
