Calorimetric evidence for two phase transitions in Ba $_{1 - x}$ K $_{x}$ Fe $_{2}$ As $_{2}$ with fermion pairing and quadrupling states

Ilya Shipulin, Nadia Stegani, Ilaria Maccari +9

Theoretically, materials that break multiple symmetries allow, under certain conditions, the formation of four-fermion condensates above the superconducting critical temperature. S…

Prediction of time-reversal-symmetry breaking fermionic quadrupling condensate in twisted bilayer graphene

Ilaria Maccari, Johan Carlström, Egor Babaev

Recent mean-field calculations suggest that the superconducting state of twisted bilayer graphene exhibits either a nematic order or a spontaneous breakdown of the time-reversal sy…

Effects of intercomponent couplings on the appearance of time-reversal symmetry breaking fermion quadrupling state in two-component London models

Ilaria Maccari, Egor Babaev

A detection of bosonic metallic state that breaks the $Z_{2}$ time-reversal symmetry has been recently reported in Ba $_{1 - x}$ K $_{x}$ Fe $_{2}$ As $_{2}$ with a doping level $x \approx 0.8$ . Th…
