Symmetry-Broken Eccentric Campanile Probe for Polarization-Insensitive Broadband Nanofocusing with Strong Resonant Field Enhancement

The authors present a symmetry-broken eccentric campanile probe that overcomes the polarization sensitivity and weak field enhancement of conventional plasmonic fiber probes by suppressing destructive interference and utilizing a Fabry–Pérot cavity, thereby enabling polarization-insensitive, broadband nanofocusing with strong resonant field enhancement for super-resolution imaging.

Terahertz field-induced giant symmetry modulations in a van der Waals antiferromagnet

This study demonstrates that strong-field terahertz excitations induce giant, long-lived symmetry modulations and coherent phonon dynamics in the van der Waals antiferromagnet MnPS $_3$ , revealing a field-driven mechanism for manipulating magnetism and accessing hidden vibrational modes through dynamic symmetry breaking.

Two‑Color Symmetry of the Fujiwara–Algoet Tetrahedron and Its Inversion Domains

This paper reveals a previously unexamined two-color symmetry within the Fujiwara–Algoet tetrahedron's orientation-inverting region, distinguishing a unique SU(2)-covariant part from three anisotropic ones, and proposes a practical three-state protocol to experimentally detect these orientation inversions.
