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…
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…
Loss of Causality in Discretized Light-Cone Quantisation
T. Heinzl, H. Kröger, N. Scheu
We demonstrate that front form quantisation with periodicity in a compact light-like direction (discretized light-cone quantisation) violates microcausality.
Computation of Structure Functions From a Lattice Hamiltonian
Helmut Kroger, Norbert Scheu
We compute structure functions in the Hamiltonian formalism on a momentum lattice using a physically motivated regularisation that links the maximal parton number to the lattice si…
