Analytic eigenvalue structure of a coupled-oscillator system beyond the ground state
By analytically continuing the eigenvalue problem of a system of two coupled harmonic oscillators in the complex coupling constant g, we have found a continuation structure through which the conventional ground state of the decoupled system is connected to three other lower unconventional ground sta...
