Equation of state of strongly coupled QCD at finite density
Yasuo Umino
Using an effective strongly coupled lattice QCD Hamiltonian and Wilson fermions we calculate the equation of state for cold and dense quark matter by constructing an ansatz which e…
Hamiltonian lattice QCD at finite density: equation of state in the strong coupling limit
Yasuo Umino
The equation of state of Hamiltonian lattice QCD at finite density is examined in the strong coupling limit by constructing a solution to the equation of motion corresponding to an…
Equation of state of strongly coupled Hamiltonian lattice QCD at finite density
Yasuo Umino
We calculate the equation of state of strongly coupled Hamiltonian lattice QCD at finite density by constructing a solution to the equation of motion corresponding to an effective…
Diagonalization of the strongly coupled lattice QCD Hamiltonian
Yasuo Umino
We construct a solution to the equation of motion of Hamiltonian lattice QCD in the strong coupling limit using Wilson fermions which exactly diagonalizes the Hamiltonian to second…
The 't Hooft interaction at finite T and : Beyond the mean field theory
Yasuo Umino, Vicente Vento
We use the N-quantum approach (NQA) to quantum field theory to construct a solution of the two flavor effective instanton induced `t Hooft interaction model valid for any temperatu…
N-quantum approach to quantum field theory at finite T and : the NJL model
Yasuo Umino, Vicente Vento
We extend the N-quantum approach to quantum field theory to finite temperature () and chemical potential () and apply it to the NJL model. In this approach the Heisenberg fie…
