A Torelli-type theorem for hyperkähler quotients
Ryota Kotani
In this paper, we investigate the moduli space of algebraic asymptotic hyperkähler structures on hyperkähler quotients arising from a quaternionic vector space . We c…

Bridging Pico-to-Nanonewtons with a Ratiometric Force Probe for Monitoring Nanoscale Polymer Physics Before Damage
Ryota Kotani, Soichi Yokoyama, Shunpei Nobusue +4
Understanding the transmission of nanoscale forces in the pico-to-nanonewton range is important in polymer physics. While physical approaches have limitations in analyzing the loca…
