Alternative Perspective on Quantum Tunneling and Instantons
F. Paradis, H. Kroger, G. Melkonyan +1
We present a new way to compute and interpret quantum tunneling in a 1-D double-well potential. For large transition time we show that the quantum action functional gives an analyt…
What does quantum chaos mean?
D. Huard, H. Kroger, G. G. Melkonyan +2
We discuss how the concept of the quantum action can be used to characterize quantum chaos. As an example we study quantum mechanics of the inverse square potential in order to tes…
Quantum chaos viewed from quantum action
D. Huard, H. Kröger, G. Melkonyan +2
We consider a mixed chaotic Hamiltonian system and compare classical with quantum chaos. As alternative to the methods of enegy level spacing statistics and trace formulas, we cons…
Thermodynamics from Monte Carlo Hamiltonian
L. A. Caron, H. Kröger, G. Melkonyan +2
We construct an effective low-energy Hamiltonian from the classical action via Monte Carlo with importance sampling. We use Monte Carlo (i) to compute matrix elements of the transi…
