Fluctuation Statistics and Diffusive Properties of the 2D Triangular Lorentz Gas in the Finite-Horizon Regime
A. Hosseinizadeh, J. F. Laprise, H. Kröger +2
We study chaotic behavior and diffusion in the 2D periodic Lorentz gas in the finite-horizon regime. The dynamical observable which we consider is the length of single particle's t…
Excited States of U(1) Lattice Gauge Theory from Monte Carlo Hamiltonian
A. Hosseinizadeh, G. Melkonyan, H. Kröger +2
We address an old problem in lattice gauge theory - the computation of the spectrum and wave functions of excited states. Our method is based on the Hamiltonian formulation of latt…
Universality of Level Spacing Distributions in Classical Chaos
J. F. Laprise, J. Kroger, H. Kroger +7
We suggest that random matrix theory applied to a classical action matrix can be used in classical physics to distinguish chaotic from non-chaotic behavior. We consider the 2-D sta…
Stationary Points of Scalar Fields Coupled to Gravity
H. Kroger, G. Melkonyan, F. Paradis +1
We investigate the dynamics of gravity coupled to a scalar field using a non-canonical form of the kinetic term. It is shown that its singular point represents an attractor for cla…
Quantum Chaos Versus Classical Chaos: Why is Quantum Chaos Weaker?
H. Kroger, J. F. Laprise, G. Melkonyan +1
We discuss the questions: How to compare quantitatively classical chaos with quantum chaos? Which one is stronger? What are the underlying physical reasons?
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…
