Spin Transitions in Graphene Butterflies at an Integer Filling Factor
Arag Ghazaryan, Tapash Chakraborty
Recent experiments on the role of electron-electron interactions in fractal Dirac systems have revealed a host of interesting effects, in particular, the unique nature of the magne…
Fractional Quantum Hall Effect in Hofstadter Butterflies of Dirac Fermions
Areg Ghazaryan, Tapash Chakraborty, Pekka Pietilainen
We report on the influence of a periodic potential on the fractional quantum Hall effect (FQHE) states in monolayer graphene. We have shown that for two values of the magnetic flux…
Tuning of Exciton States in a Magnetic Quantum Ring
Areg Ghazaryan, Aram Manaselyan, Tapash Chakraborty
We have studied the exciton states in a CdTe quantum ring in an external magnetic field containing a single magnetic impurity. We have used the multiband approximation which includ…
Emergent Geometry Fluctuation in Quantum Confined Electron Systems
Areg Ghazaryan, Tapash Chakraborty
The intrinsic geometric degree of freedom that was proposed to determine the optimal correlation energy of the fractional quantum Hall states, is analyzed for quantum confined plan…
