Giant viscosity enhancement in a spin-polarized fermi liquid
Fermi liquid viscosity mixture high magnetic field
font style='font-size:12px;'>
2014/12/20
The viscosity is measured for a Fermi liquid, a dilute 3He-4He mixture, under extremely high magnetic field/temperature conditions (B≤14.8 T, T≥1.5 mK). The spin-splitting en...
