Structure and mechanical and thermal properties in condensed matter

This study reports the direct observation of piezoelectricity in the spin-orbit-coupled metal Cd₂Re₂O₇. The findings reveal how electric toroidal quadrupole order drives successive inversion-symmetry-breaking transitions and anisotropic electromechanical responses.

Superconductivity

The initial slope method is used to reveal intrinsic electronic specific heat by eliminating the overwhelming nuclear contributions during low-temperature calorimetry, opening a new window into quantum materials.

Structure and mechanical and thermal properties in condensed matter

Although the Einstein–de Haas (EdH) effect describes material rotation in a magnetic field, a thermal EdH effect, driven by a temperature gradient, remains unobserved. Recently, chiral carbon nanotubes were theoretically proposed as promising candidates to observe it.

Structure and mechanical and thermal properties in condensed matter

Electrically driven liquid-crystal turbulence generates self-sustained flow and negative apparent viscosity. The fluorinated, chemically robust nematic PPDFB shows a substantially larger negative-viscosity effect than Schiff-base nematics.
