Collective Spin and Charge Excitations in Planar Aromatic Molecules
K. Haghighi Mood, S. A. Jafari, E. Adibi +2
Employing high accuracy fixed node diffusion Monte Carlo (DMC) method we calculated the lowest triplet collective excitation (spin gap), as well as an upper bound for the singlet e…
Neutral Triplet Collective Mode in Doped Graphene
M. Ebrahimkhas, S. A. Jafari, G. Baskaran
Particle-hole continuum in Dirac sea of graphene has a unique window underneath, which provides a unique opportunity for emergence of a pole in the susceptibility of the {\em tripl…

Predicting a Gapless Spin-1 Neutral Collective Mode branch for Graphite
G. Baskaran, S. A. Jafari
Using the standard tight binding model of 2d graphite with short range electron repulsion, we find a gapless spin-1, neutral collective mode branch {\em below the particle-hole con…
