Mass Ladder Operators from Spacetime Conformal Symmetry
Vitor Cardoso, Tsuyoshi Houri, Masashi Kimura
Ladder operators can be useful constructs, allowing for unique insight and intuition. In fact, they have played a special role in the development of quantum mechanics and field the…

General first-order mass ladder operators for Klein-Gordon fields
Vitor Cardoso, Tsuyoshi Houri, Masashi Kimura
We study the ladder operator on scalar fields, mapping a solution of the Klein-Gordon equation onto another solution with a different mass, when the operator is at most first order…

A simple test for stability of black hole by -deformation
Masashi Kimura
We study a sufficient condition to prove the stability of a black hole when the master equation for linear perturbation takes the form of the Schrödinger equation. If the potential…
