Role of correlations in determining the Van Hove strain in Sr2RuO4
Physical review B
Uniaxial pressure applied along an Ru-Ru bond direction induces an elliptical distortion of the largest Fermi surface of Sr2RuO4, eventually causing a Fermi surface topological transition, also known as a Lifshitz transition, into an open Fermi surface. There are various anomalies in lowtemperature properties associated with this transition, including maxima in the superconducting critical temperature and in resistivity. In the present paper, we report new measurements, employing new uniaxialdoi:10.1103/physrevb.100.245139 fatcat:djjiu557cvgztapk3tje47lole
