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.

Structure and mechanical and thermal properties in condensed matter

In many energy devices, electron transfer occurs between ions dissolved in the electrolyte and the electrodes. For keep current flowing, new ions must be supplied continuously to the electrode surface from the bulk region. The diffusion layer’s role in diffusive mass transfer was clarified using the rotating disk electrode method.

Superconductivity

Using high-quality UTe₂ (T_c = 2.1 K), we identify its nodal gap structure. Field-angle‑resolved specific‑heat reveals a b-axis singularity, supporting spin-triplet superconductivity with nodes along the b axis.

Structure and mechanical and thermal properties in condensed matter

Chiral crystals host phonons with intrinsic angular momentum, whose quantization and energy splitting reflect the lattice chirality and reveal the microscopic features of interatomic interactions.
