High-order alloharmonics produced by nonperiodic drivers
M. S. Pirozhkova, K. Ogura, A. Sagisaka +18
High-order harmonics are ubiquitous in nature and present in electromagnetic, acoustic, and gravitational waves. They are generated by periodic nonlinear processes or periodic high…

Demonstration of The Brightest Nano-size Gamma Source
A. S. Pirozhkov, A. Sagisaka, K. Ogura +46
Gamma rays selectively interact with nuclei, induce and mediate nuclear reactions and elementary particle interactions, and exceed x-rays in penetrating power and thus are indispen…
