A new picture of quantum tunneling in the real-time path integral from Lefschetz thimble calculations
Abstract It is well known that quantum tunneling can be described by instantons in the imaginary-time path integral formalism. However, its description in the real-time path integral formalism has been elusive. Here we establish a statement that quantum tunneling can be characterized in general by t...
