On resumming periodic orbits in the spectra of integrable systems
Alfredo M. Ozorio de Almeida, Caio H. Lewenkopf, Steven Tomsovic
Spectral determinants have proven to be valuable tools for resumming the periodic orbits in the Gutzwiller trace formula of chaotic systems. We investigate these tools in the conte…
