Luminescence Spectra of a Quantum-Dot Cascade Laser
Vadim Apalkov, Tapash Chakraborty
A quantum cascade laser where the quantum wells in the active regions are replaced by quantum dots with their atom-like discrete energy levels is an interesting system to study nov…
Influence of disorder and a parallel magnetic field on a Quantum Cascade Laser
V. M. Apalkov, Tapash Chakraborty
The luminescence spectra of a quantum cascade laser in a strong magnetic field is influenced significantly by the presence of disorder (charged or neutral) in the system. An extern…
Magnetic field induced luminescence spectra in a quantum cascade laser
V. M. Apalkov, T. Chakraborty
We report on our study of the luminescence spectra of a quantum cascade laser in the presence of an external magnetic field tilted from the direction perpendicular to the electron…
Theory of the Half-Polarized Quantum Hall States
V. M. Apalkov, T. Chakraborty, P. Pietilainen +1
We report a theoretical analysis of the half-polarized quantum Hall states observed in a recent experiment. Our numerical results indicate that the ground state energy of the quant…
Comment on ``Composite Fermion Hofstadter Problem: Partially Polarized Density Wave States in the ...''
V. M. Apalkov, T. Chakraborty, P. Pietilainen +1
In a recent paper [Phys.Rev.Lett. 82, 3665 (1999)], magnetic field driven spin transitions in fractional quantum Hall (FQH) states were reported, and in particular, at filling fact…
