Collective excitations in liquid bismuth
Collective excitations in liquid bismuth is a scholarly work by Taras Bryk, published in 2000 in ''Journal of Physics: Condensed Matter''. The main subjects of the publication include alloy, spectral line, physics, bismuth, quasiparticle, quantum mechanics, semimetal, spectrum, energy density, spectrum, basis, statistical physics, and condensed matter physics. From the analysis of spectra obtained for different basis sets of dynamical variables it is found that the high-frequency branch of propagating collective excitations corresponds to heat waves in the liquid.
