On the one-particle reduced density matrices of a pure three-qutrit quantum state
Atsushi Higuchi
We present a necessary and sufficient condition for three qutrit density matrices to be the one-particle reduced density matrices of a pure three-qutrit quantum state. The conditio…

Radiation reaction in quantum mechanics
Atsushi Higuchi
The Lorentz-Dirac radiation reaction formula predicts that the position shift of a charged particle due to the radiation reaction is of first order in acceleration if it undergoes…

Bremsstrahlung by static charges outside a static black hole ?
G. E. Matsas, D. Sudarsky, A. Higuchi
We show that in complete analogy with the usual bremsstrahlung process, when studied from the coaccelerated observer's point of view, a charge moving along the integral curves of t…
