Аннотация:
We study the temperature evolution of the single-particle spectrum $\epsilon(p)$
and quasiparticle momentum distribution $n(p)$ of homogeneous strongly correlated
Fermi systems beyond a point where the necessary condition for stability of
the Landau state is violated, and the Fermi surface becomes multi-connected by
virtue of a topological crossover. Attention is focused on the different
non-Fermi-liquid temperature regimes experienced by a phase exhibiting a
single additional hole pocket compared with the conventional Landau state.
A critical experiment is proposed to elucidate the origin of NFL behavior
in dense films of liquid $^3$He.
