Diffusive Nambu-Goldstone modes in quantum time-crystals
Tomoya Hayata, Yoshimasa Hidaka
We study the Nambu-Goldstone (NG) modes associated with spontaneous breaking of the continuous time-translation symmetry. To discuss a quantum time-crystal with the spontaneously-b…

Negative refractive index in cubic noncentrosymmetric superconductors
Tomoya Hayata
We study the negative refractive index in cubic noncentrosymmetric superconductors. We consider the Maxwell equations under the Meissner effect, and magnetoelectric effect arising…

A new route to negative refractive index from topological metals
Tomoya Hayata
We theoretically discuss the possibility of realizing the negative refractive index in Weyl/Dirac semimetals. We consider the Maxwell equations with the plasma gap and the chiral m…
