Quantum Instantons and Quantum Chaos
H. Jirari, H. Kröger, X. Q. Luo +2
Based on a closed form expression for the path integral of quantum transition amplitudes, we suggest rigorous definitions of both, quantum instantons and quantum chaos. As an examp…

Monte Carlo Hamiltonian
H. Jirari, H. Kröger, X. Q. Luo +1
We construct an effective Hamiltonian via Monte Carlo from a given action. This Hamiltonian describes physics in the low energy regime. We test it by computing spectrum, wave funct…
