Screening finds 180 materials with significant altermagnetic spin splitting
What the study found The study found 180 materials with significant altermagnetic spin splitting. These materials include both metallic and semiconducting systems, and some representative cases discussed are UCr2Si2C, NbMnP, and YRuO3. Why the authors say this matters The authors say altermagnetism is promising for next-generation spintronics because it can produce sizable spin splitting in…
Boundary layer transition follows symmetry-breaking stages
What the study found The study finds that boundary layer transition in canonical K-type flow is not unstructured noise, but a sequence of organized temporal and spatial symmetry-breaking stages with measurable energy pathways. The authors describe a periodic, spanwise-symmetric fundamental harmonic response, followed by quasi-periodic, aperiodic, and then anti-symmetric structures. Why the authors say this…
2D Abelian gauge theories show rich phase structure
What the study found Abelian gauge theories in 1+1 dimensions can have a surprisingly rich phase structure as masses are varied. The abstract says these systems include critical lines or points with central charge c = 1 and c = 1/2, and it also points to 2D chiral gauge theories as a setting for symmetric…
