Photoluminescence signature of skyrmions at ν= 1
T. Portengen, J. R. Chapman, V. Nikos Nicopoulos +1
The photoluminescence spectrum of quantized Hall states near filling factor ν= 1 is investigated theoretically. For ν>= 1 the spectrum consists of a right-circularly polarized (RCP…
Stability of optically-active charged excitons in quasi-two dimensional systems
James R. Chapman, Neil F. Johnson, V. Nikos Nicopoulos
A negatively charged quasi-two dimensional exciton () is solved exactly numerically in the presence of a uniform perpendicular B-field. Various quasi-two dimensional geometrie…
Ginzburg-Landau-Gor'kov Theory of Magnetic oscillations in a type-II 2-dimensional Superconductor
G. M. Bruun, V. N. Nicopoulos, N. F. Johnson
We investigate de Haas-van Alphen (dHvA) oscillations in the mixed state of a type-II two-dimensional superconductor within a self-consistent Gor'kov perturbation scheme. Assuming…
Optical properties of a two-dimensional electron gas at even-denominator filling fractions
Darren J. T. Leonard, Neil F. Johnson, V. Nikos Nicopoulos +1
The optical properties of an electron gas in a magnetic field at filling fractions ν= {1\over 2m} (m=1,2,3...) are investigated using the composite fermion picture. The response of…
