← ScienceDuring cryogenic storage of liquid helium II, which mechanism causes persistent superfluid creep?
A)Onsager’s quantized vortex formation✓
B)Increased isotopic helium-3 abundance
C)Enhanced container wall adhesion
D)Suppressed convective heat transfer
💡 Explanation
Superfluid creep arises from Onsager’s quantized vortex formation because these vortices carry momentum within the superfluid, allowing helium II to creep up container walls to equalize chemical potential, therefore the persistent superflow, rather than other thermal effects, occurs.
