Calorimetric evidence for two phase transitions in Ba_1−xK_xFe₂As₂ with fermion pairing and quadrupling states

The authors report two anomalies in the specific heat of (Ba,K)Fe₂As₂, providing thermodynamic confirmation of the separation of superconducting T_c and the onset of time-reversal symmetry breaking (TRSB). Further, they argue that the TRSB is associated with a four-fermion condensate induced by phase fluctuations.

Purely antiferromagnetic magnetoelectric random access memory

Magnetoelectric coupling allows switching of magnetic states via gate voltage pulses. Here the authors propose and demonstrate a purely antiferromagnetic magnetoelectric random access memory based on Cr₂O₃, reporting 50-fold reduction of writing threshold compared to ferromagnetic counterparts.

State with spontaneously broken time-reversal symmetry above the superconducting phase transition

A state that breaks time-reversal symmetry is observed in the normal phase above the superconducting critical temperature in a multiband superconductor. This could be explained by correlations between the Cooper pairs formed in different bands.

Experimental signatures of the mixed axial–gravitational anomaly in the Weyl semimetal NbP

A positive magneto-thermoelectric conductance is observed in the Weyl semimetal niobium phosphide, suggesting the presence of the elusive mixed axial–gravitational anomaly.
