Ubiquitous enhancement of nematic fluctuations across the phase diagram of iron based superconductors probed by the Nernst effect
Abstract The role of nematic fluctuations for unconventional superconductivity has been the subject of intense discussions for many years.In iron-based superconductors, the most established probe for electronic-nematic fluctuations, i.e.the elastoresistivity seems to imply that superconductivity is reinforced by electronic-nematic fluctuations, sin
