Thermal stability originates the vanishing of the specific heats at absolute zero
The relationship between the vanishing of the heat capacities as $T\to0^+$ and the thermal stability is examined. The heat capacities vanish as fast as or faster than $T$ as $T\to0^+$ for states at th...

16. My conclusion: we do not need a new law to codify this behaviour. The general properties of matter at absolute zero can be deduced from the two main laws of thermodynamics.

15. Back to curvature. At T=0, U(S) has zero slope. Therefore, the issue is how much flat U(S) can be to sustain stability. Conditions shallower than a parabola would not sustain stability and are abhorred. Conditions stiffer than a parabola are welcome.

14. A non-varying specific heat [the old, venerable Dulong-Petit law] in T->0 would yield an exponential loss of curvature. The system would trigger extremely large critical fluctuations. Nature just abhors putting itself in such jeopardy.

13. But in T->0, a weakly vanishing C suffices to provide curvature loss. As an example C~√T does not sustain the stability condition at T=0. Strongly correlated systems exhibit this behaviour named quantum critical point (QCP): a critical behaviour precisely at T=0.

12. In standard T>0 conditions, the loss of stability is associated with curvature loss in u(s). This requires C increasing indefinitely to infinity, giving rise to critical fluctuations and critical phenomena. Watch this (unrelated to the specific heat) youtube.com/watch?v=VGxW...

11. Usual observations in crystalline solids, electronic contribution, and son on, and useful models (Debye, Sommerfeld, Schottky) go in line with this result. They are not alien to the 2nd law but an ultimate consequence of the 2nd law of thermodynamics.

10. But, if T->0, then the standard condition changes into "C must vanish as fast as T or faster". C~T^3 is ok, C~T, also; but C~√T is not ok with stability at absolute zero. This is new in doi.org/10.1088/1402...

9. Therefore, at non-zero temperature T>0 the standard stability condition is read as: C must be finite, positive for thermal stability to sustain. Every textbook in thermodynamics goes in this line.

8. Positive specific heats goes the other way around. The inhomogeneity gets larger energy for the same entropy and regrouping is favored by the release of such energy. Inhomogeneities did not grow too much. Equilibrium is stable. Fluctuations are minimal.

7. In thermodynamics, c is related to stability. Negative c would render unstable "equilibrium" states bc if the system got divided in two, the sum of the two partition would have less energy than the total. Regrouping would be inhibited. Inhomogeneities would grow indefinitely.

Quantum physics is always in the core explanation, alien to the 2nd law of thermod.

5. In 1907 Einstein provided an explantition. The second success by the emergin quantum theory. First time quantum physics was applied to real matter (ie not photons). In 1912 Debye refined the thing and got the T^3 law for the vanishing specific heats.

4. At room temperature specific heat of solids usually range 3R (ideal gas constant) (Dulong and Petit 1819). Equipartition theorem provides explanation. At low temperature this dramatically fails to sustain. No classical explanation existed.

3. Non-zero specific heat means energy is required to change temperature. The vanishing of the specific heats means few energy, if any, is needed to alter temperature at absolute zero. Which indirectly explains the challenging conditions around T=0.

2. The specific heat measures the opposition to change temperature upon a given change of energy. Larger C requires more energy (u) to sustain the same change of T. Specific heat is related to the curvature of u(s) along s (entropy). More curvature--> less C --> T changes quickly.
