Mathematical modeling of morphological changes in photochromic crystals by catastrophe theory
Hirotsugu Suzui, Kazuharu Uchiyama, Kingo Uchida +3
Photochromic diarylethene is known to exhibit reversible photoisomerization under irradiation with ultraviolet (UV) and visible light. Besides reversible optical properties upon li…
History-dependent nano-photoisomerization by optical near-field in photochromic single crystals
Yuji Arakawa, Kazuharu Uchiyama, Kingo Uchida +2
We demonstrate history-dependent or dynamic nano-photoisomerization by sequential formation of multiple memory pathways in photochromic crystals via optical near-field interactions…
Order recognition by Schubert polynomials generated by optical near-field statistics via nanometre-scale photochromism
Kazuharu Uchiyama, Sota Nakajima, Hirotsugu Suzui +6
We have previously observed an irregular spatial distribution of photon transmission through a photochromic crystal photoisomerized by a local optical near-field excitation, manife…
Generation of Schubert polynomial series by nanophotonics
Hirotsugu Suzui, Kazuharu Uchiyama, Ryo Nakagomi +4
Generation of irregular time series based on physical processes is indispensable in computing and artificial intelligence. In this report, we propose and experimentally demonstrate…
Ubiquitous V-shape density of states in mixed state of clean limit type II superconductors; STM experiment and theory
N. Nakai, P. Miranovic, M. Ichioka +6
It is demonstrated theoretically and experimentally that the low energy density of states is described by a singular V-shape form for all clean sup…
