Grüneisen parameter as an entanglement compass and the breakdown of the Hellmann-Feynman theorem
Lucas Squillante, Luciano S. Ricco, Aniekan Magnus Ukpong +3
The Grüneisen ratio , i.e., the singular part of the ratio of thermal expansion to the specific heat, has been broadly employed to explore both finite- and quantum critical…
