Intersubband magnetophonon resonances in quantum cascade structures
D. Smirnov, O. Drachenko, J. Leotin +5
We report on our magnetotransport measurements of GaAs/GaAlAs quantum cascade structures in a magnetic field of up to 62 T. We observe novel quantum oscillations in tunneling curre…

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…
