Simulated quantum annealing of double-well and multiwell potentials.

We analyze the performance of quantum annealing as a heuristic optimization method to find the absolute minimum of various continuous models, including landscapes with only two wells and also models with many competing minima and with disorder. The simulations performed using a projective quantum Monte Carlo (QMC) algorithm are compared with those based on the finite-temperature path-integral Q...

Energy splitting in symmetric double-well potentials

The quantum mechanical tunnelling in a smooth symmetric double-well potential is a long-standing and well-known problem. Three methods have been proposed to calculate the energy splitting: the instanton method @1,2#, the WKB approximation @3,4# and numerical calculation @4–6#. The instanton method is helpful to understand the physical insight of quantum tunnelling, but the validity is restricte...

Quantum kink model and Razavi double-well potentials related to SU(2) symmetry

In the present paper we consider a class of exact solutions of the Schröedinger equation with the Razavi potential. By means of this we obtain some wave functions and mass spectra of relativistic scalar field model with spontaneously broken symmetry about static kink solution. Also an appearance in the theory of bosons, which have two different spins, will be shown. Herewith the breaking of sym...

Atomic motion in magneto-optical double-well potentials: A new testing ground for quantum chaos

We have identified ultra-cold atoms in magneto-optical double-well potentials as a very clean setting in which to study the quantum and classical dynamics of a nonlinear system with multiple degrees of freedom. In this system, entanglement at the quantum level and chaos at the classical level arise from nonseparable couplings between the atomic spin and its center of mass motion. The main featu...
