quantum hydrodynamics

Quantum hydrodynamics is a field that describes the flow of quantum fluids—like superfluid helium or atomic Bose-Einstein condensates—using fluid dynamics principles. It captures how these fluids behave at very small scales, incorporating quantum effects such as wave-like properties and quantized vortices. Unlike classical fluids, their motion is governed by quantum mechanics, leading to unique phenomena like frictionless flow and discrete vortices. Quantum hydrodynamics provides a framework to understand these behaviors, bridging fluid mechanics and quantum physics to study systems where quantum effects dominate fluid behavior.
