Quantum fluctuation-driven transport crossover between two liquid states in distinguishable helium-4
Summary
arXiv:2607.23127v1 Announce Type: cross Abstract: We show the emergence of a quantum fluctuation-driven transport crossover between two liquid states in distinguishable helium-4 obeying Boltzmann statistics, in the absence of atomic exchange. Using path integral centroid molecular dynamics simulations over 0.1-3.3 K and 1-60 bar, we investigate the transport properties of two distinct liquid states: the low quantum-dispersion liquid (LQDL) and the high quantum-dispersion liquid (HQDL). While LQDL exhibits conventional liquid behavior consistent with the Stokes-Einstein (SE) relation, HQDL emerges at lower temperatures and displays anomalous gas-like transport characterized by superdiffusion and ultralow viscosity, accompanied by a breakdown of the SE relation.
Why It Matters
This Quantum development moves quantum capability closer to commercial and national-security relevance. For Asia, it is a signal worth tracking: it shapes who supplies, who scales, and who sets the standard over the next five years.
