Abstract
Spectra of collective and magnetic excitations in symmetric double
quantum wells with strong tunnel coupling were studied by inelastic
scattering. Gaps in the spectrum of collective and single-particle
excitations associated with tunnel interwell splitting were measured.
New excitation modes, namely, tunnel Bernstein modes, were detected in
a magnetic field. Based on the dispersion and magnetic-field
dependences of the energies of inelastic light scattering lines, a
classification of excitations and magnetic excitations was given. (C)
