What the article says around this equation
No part of this history attracts more overclaiming than the search for a superconductor that needs no refrigeration at all. The physical logic for looking at hydrogen-rich compounds under extreme pressure is sound and traces to a real prediction: hydrogen, compressed enough, should behave like a light, strongly-bonded lattice with a very high phonon frequency — precisely the quantity that the BCS formula above says should raise . Superconductivity near 203 kelvin was confirmed in compressed hydrogen sulfide in 2015 and above 250 kelvin in a lanthanum hydride in 2019, both under pressures around 150–200 gigapascals — genuine, independently reproduced results, though far from…
