Thermodynamic Explanation of the Meissner-Ochsenfeld Effect in Superconductors
Phil Attard
The thermodynamic principle of superfluid flow -- that the energy is minimized at constant entropy -- is applied to superconducting currents to derive the Meissner-Ochsenfeld effec…

The Two-Fluid Theory for Superfluid Hydrodynamics and Rotational Motion
Phil Attard
The two-fluid theory for superfluid hydrodynamics is derived from the fountain pressure result that condensed bosons move at constant entropy and are driven by the chemical potenti…

Ten Equations that Shook the Quantum World: Bose-Einstein Condensation, Superfluidity, and the Quantum-Classical Transition
Phil Attard
The transition from the quantum to the classical world and its relation to Bose-Einstein condensation and superfluidity is explained in ten equations.
