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…
