Simulation of positronium laser cooling using the Lindblad master equation
Kenji Shu, Sohma Shiraishi, Kosuke Yoshioka
We present a formulation and numerical results for positronium (Ps) laser cooling. The formulation is based on the Lindblad master equation and follows the time evolution of the de…

Development of an optimal laser for chirp cooling of positronium based on chirped pulse-train generator
Kenji Shu, Naoki Miyamoto, Yuto Motohashi +3
We report the development and characterization of a pulsed 243 nm laser that is optimal for the cooling of positronium (Ps). The laser, which is based on the recent chirped pulse-t…
