QCD at Finite Density
Xiang-Qian Luo, Eric B. Gregory, Shuo-Hong Guo +1
At sufficiently high temperature and density, quantum chromodynamics (QCD) predicts phase transition from the hadronic phase to the quark-gluon plasma phase. Lattice QCD is the mos…
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…
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…
Improved Lattice Gauge Field Hamiltonian
Xiang-Qian Luo, Shuo-Hong Guo, H. Kröger +1
Lepage's improvement scheme is a recent major progress in lattice , allowing to obtain continuum physics on very coarse lattices. Here we discuss improvement in the Hamiltonia…
Improving the Lattice QCD Hamiltonian
Xiang-Qian Luo, Shuo-Hong Guo, Helmut Kroeger +1
Improvement of the Hamiltonian in lattice gauge theory is considered. We give explicit expressions for classical improvement and discuss also quantum corrections.
Method for Extracting the Glueball Wave Function
J. Liu, X. Q. Luo, X. Fang +4
We describe a nonperturbative method for calculating the QCD vacuum and glueball wave functions, based on an eigenvalue equation approach to Hamiltonian lattice gauge theory. There…
