Higher time derivatives in effective equations of canonical quantum systems
arXiv:1208.1242 · doi:10.1103/PhysRevD.86.105004
Abstract
Quantum-corrected equations of motion generically contain higher time derivatives, computed here in the setting of canonically quantized systems. The main example in which detailed derivations are presented is a general anharmonic oscillator, but conclusions can be drawn also for systems in quantum gravity and cosmology.
