Thermodynamic holography [PDF]
Scientific Reports, 2015 AbstractThe holographic principle states that the information about a volume of a system is encoded on the boundary surface of the volume. Holography appears in many branches of physics, such as optics, electromagnetism, many-body physics, quantum gravity and string theory. Here we show that holography is also an underlying principle in thermodynamics,

Unitary Thermodynamics from Thermodynamic Geometry [PDF]
Journal of Low Temperature Physics, 2013 Degenerate Fermi gases of atoms near a Feshbach resonance show universal thermodynamic properties, which are here calculated with the geometry of thermodynamics, and the thermodynamic curvature $R$. Unitary thermodynamics is expressed as the solution to a pair of ordinary differential equations, a "superfluid" one valid for small entropy per atom $z ...
