Undecidability, entropy and information loss in computations of classical physical systems
Sungyun Kim
We investigate how undecidability enters into computations of classical physical systems and contributes to the increase of entropy and loss of information. In actual computation w…

A new way of defining unstable states
Sungyun Kim, Gonzalo Ordonez
We define a new unstable state in the Friedrichs model of a two-level atom. This unstable state is a complex eigenstate of the time evolution operator with a restricte…
