Improved design and experimental demonstration of ultrahigh-Q C-symmetric H1 hexapole photonic crystal nanocavities
Kenta Takata, Eiichi Kuramochi, Akihiko Shinya +1
An H1 photonic crystal nanocavity is based on a single point defect and has eigenmodes with a variety of symmetric features. Thus, it is a promising building block for photonic tig…
Network of Time-Multiplexed Optical Parametric Oscillators as a Coherent Ising Machine
Alireza Marandi, Zhe Wang, Kenta Takata +2
Finding the ground states of the Ising Hamiltonian [1] maps to various combinatorial optimization problems in biology, medicine, wireless communications, artificial intelligence, a…
Universal valence-band picture of the ferromagnetic semiconductor GaMnAs
Shinobu Ohya, Kenta Takata, Masaaki Tanaka
The origin of ferromagnetism in the prototype ferromagnetic semiconductor GaMnAs is still controversial due to the insufficient understanding of its band structure and Fermi level…
