Monte Carlo Hamiltonian from Stochastic Basis
C. Q. Huang, H. Kröger, X. Q. Luo +1
In order to extend the recently proposed Monte Carlo Hamiltonian to many-body systems, we suggest to concept of a stochastic basis. We apply it to the chain of coupled anha…
Hamiltonian lattice QCD at finite chemical potential
E. B. Gregory, S. Guo, H. Kroger +1
At sufficiently high temperature and density, quantum chromodynamics (QCD) is expected to undergo a phase transition from the confined phase to the quark-gluon plasma phase. In the…
The Star Formation History of the Starburst Region NGC 2363 and its Surroundings
L. Drissen, J. -R. Roy, C. Robert +2
We present HST optical images and UV spectra, as well as ground-based near-infrared images of the high surface brightness giant HII region NGC 2363 (NGC 2366-I) and its surrounding…
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…
Closed Path Integrals and Renormalisation in Quantum Mechanics
H. Jirari, H. Kröger, X. Q. Luo +2
We suggest a closed form expression for the path integral of quantum transition amplitudes. We introduce a quantum action with renormalized parameters. We present numerical results…
Monte Carlo Hamiltonian - From Statistical Physics to Quantum Theory
Xiang-Qian Luo, C. Huang, J. Jiang +3
Monte Carlo techniques have been widely employed in statistical physics as well as in quantum theory in the Lagrangian formulation. However, in some areas of application to quantum…
