Critical intermediate phase and phase transitions in a triangular-lattice three-spin interaction model: Level-spectroscopy approach
Hiromi Otsuka, Kiyohide Nomura
We investigate infinite-order phase transitions like the Berezinskii-Kosterlitz-Thouless transition observed in a triangular-lattice three-spin interaction model. Based on a field…
Explosive fragmentation of thin ceramic tube using pulsed power
Hiroaki Katsuragi, Satoshi Ihara, Haruo Honjo
This study experimentally examined the explosive fragmentation of thin ceramic tubes using pulsed power. A thin ceramic tube was threaded on a thin copper wire, and high voltage wa…
Crossover of the weighted mean fragment mass scaling in 2D brittle fragmentation
Hiroaki Katsuragi, Daisuke Sugino, Haruo Honjo
We performed vertical and horizontal sandwich 2D brittle fragmentation experiments. The weighted mean fragment mass was scaled using the multiplicity . The scaling exponent cros…
Scaling of impact fragmentation near the critical point
Hiroaki Katsuragi, Daisuke Sugino, Haruo Honjo
We investigated two-dimensional brittle fragmentation with a flat impact experimentally, focusing on the low impact energy region near the fragmentation-critical point. We found th…
