N-fold topological mode replication in hierarchical honeycomb lattices
Keita Funayama, Kenichi Yatsugi, Hideo Iizuka
Multi-band topological states enable robust and versatile wave manipulation across a variety of physical platforms. However, the emergence of multi-band topological states has reli…
Realization of a universal topological waveguide by tuning adiabatic geometry
Keita Funayama, Jotaro J. Nakane, Ai Yamakage
Quantum valley Hall-based topological phases have been attracting attention across diverse fields as a robust platform for wave guidance due to their high compatibility with engine…
Topological Phononic Crystal on the Scale of Quasi-Ballistic Phonon Transport
Keita Funayama, Yuki Akura, Hiroya Tanaka +1
Phonon engineering technology has opened up the functional thermal management of semiconductor-based classical and quantum electronics at the micro- and nanoscales. However, challe…
Selectable diffusion direction with topologically protected edge modes
Keita Funayama, Jun Hirotani, Atsushi Miura +1
Topological insulators provide great potentials to control diffusion phenomena as well as waves. Here, we show that the direction of thermal diffusion can be selected by the contri…
