OTOC and Quamtum Chaos of Interacting Scalar Fields
Wung-Hong Huang
Discretizing the scalar field theory on a lattice yields a system of coupled anharmonic oscillators with quadratic and quartic potentials. We begin by analyzing the two coup…

Third-Order Perturbative OTOC of the Harmonic Oscillator with Quartic Interaction and Quantum Chaos
Wung-Hong Huang
We calculate the third-order out-of-time-order correlator (OTOC) of a simple harmonic oscillator with an additional quartic interaction using the second quantization method. We obt…

Second-order Perturbative OTOC of Anharmonic Oscillators
Wung-Hong Huang
The out-of-time-order correlator (OTOC) of simple harmonic oscillator with extra anharmonic (quartic) interaction are calculated by the second quantization method. We obtain the an…
