Instantons and transseries of the Mathieu potential deformed by a $P T$ -symmetry parameter

N. M. Alvarenga, E. Cavalcanti, C. A. Linhares +3

We investigate the non-perturbative effects of a deformation of the Mathieu differential equation consistent with $P T$ symmetry. First, we develop a connection between th…

Energy levels for $P T$ -symmetric deformation of the Mathieu equation

E. Cavalcanti, N. M. Alvarenga, F. Reis +3

We propose a non-Hermitian deformation of the Mathieu equation that preserves $P T$ symmetry and study its spectrum and the transition from $P T$ -unbroken to $\ma…
