Cooling a polaronic liquid: Phase mixture and pseudogap-like spectra in superconducting $B{a}_{1-x}{K}_{x}Bi{O}_3$

M. Naamneh, M. Yao, J. Jandke +17

Many complex electronic systems exhibit so-called pseudogaps, which are poorly-understood suppression of low-energy spectral intensity in the absence of an obvious gap-inducing sym…
