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…
Monte Carlo Hamiltonian
H. Jirari, H. Kröger, C. Q. Huang +3
We suggest how to construct an effective low energy Hamiltonian via Monte Carlo starting from a given action. We test it by computing thermodynamical observables like average energ…
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…
Improving QCD with fermions: the 2 dimensional case of QCD with Sea Quarks
Xiang-Qian Luo, J. Jiang, S. Guo +6
We study QCD in 2 dimensions using the improved lattice fermionic Hamiltonian proposed by Luo, Chen, Xu and Jiang. The vector mass and the chiral condensate are computed for variou…
