Abstract Materials that break multiple symmetries allow the formation of four-fermion condensates above the superconducting critical temperature (T c). Such states can be stabilized by phase fluctuations. Recently, a fermionic quadrupling condensate

Publikováno v: Nature Communications, Vol 9, Iss 1, Pp 1-7 (2018)

Small structural distortions may lead to dramatic modification in the electronic states in strong correlated materials. Here, Yim et al. image a strain-stabilized smectic electronic order in LiFeAs with both broken rotational symmetry and reduced tra

Fe$_{1+x}$Te is a two dimensional van der Waals antiferromagnet that becomes superconducting on anion substitution on the Te site. The parent phase of Fe$_{1+x}$Te is sensitive to the amount of interstitial iron situated between the iron-tellurium la
