Induced discommensurations in the lock-in transition of charge-density waves
Katsuhiko Inagaki, Satoshi Tanda
We studied McMillan's free energy of the lock-in transition in charge-density waves. The wave profiles near the critical value were obtained by numerical annealing. First, we demon…
Doping-induced evolution of the intrinsic hump and dip energies dependent on the sample fabrication conditions in BiSrCaCuO
Tatsuya Honma
In oxygen-doped BiSrCaCuO, the spectra, as observed by tunneling or photoemission spectroscopic measurements, depend on the sample fabrication conditions, such…
Revisitation of the lock-in transition in one-dimensional charge-density waves
Katsuhiko Inagaki, Keiji Nakatsugawa, Satoshi Tanda
We studied the lock-in transition of charge-density waves of one-dimensional conductors. Though this phenomenon has been known for decades, there are still discrepancies between th…
Analogue black-white hole solitons in travelling wave parametric amplifiers with superconducting nonlinear asymmetric inductive elements
Haruna Katayama, Noriyuki Hatakenaka, Toshiyuki Fujii +1
We show that existing travelling wave parametric amplifier (TWPA) setups, using superconducting nonlinear asymmetric inductive elements (SNAILs), admit soliton solutions that act a…
The Nakano-Nishijima-Gell-Mann Formula From Discrete Galois Fields
Keiji Nakatsugawa, Motoo Ohaga, Toshiyuki Fujii +2
The well known Nakano-Nishijima-Gell-Mann (NNG) formula relates certain quantum numbers of elementary particles to their charge number. This equation, which phenomenologically intr…
Theoretical Studies on Quantum Walks with a Time-varying Coin
Haruna Katayama, Noriyuki Hatakenaka, Toshiyuki Fujii
Quantum walks can reconstruct quantum algorithms for quantum computation, where the precise controls of quantum state transfers between arbitrary distant sites are required. Here,…
