Phase Separation Based on U(1) Slave-boson Functional Integral Approach to the t-J Model
Tae-Hyoung Gimm, Sung-Ho Suck Salk
We investigate the phase diagram of phase separation for the hole-doped two dimensional system of antiferromagnetically correlated electrons based on the U(1) slave-boson functiona…
Effects of nonmagnetic impurities on optical conductivity in strongly correlated systems
Seung-Pyo Hong, Kwangyl Park, Sung-Ho Suck Salk
Effects of nonmagnetic impurities on optical conductivity in the systems of antiferromagnetically correlated electrons are examined based on the Lanczos exact diagonalization schem…

High Phase Diagram based on the SU(2) Slave-Boson Approach to the t-J Hamiltonian
Sung-Sik Lee, Sung-Ho Suck Salk
Based on an improved SU(2) slave-boson approach to the t-J Hamiltonian, we derive a phase diagram of high cuprates which displays both the superconducting and pseudogap phase…
Holon Pair Bose Condensation in High Cuprates; Symmetry Breaking and Supersymmetry Conditions
Sung-Sik Lee, Sung-Ho Suck Salk
Using the t-J Hamiltonian of U(1) slave-boson symmetry, bose condensation is discussed by showing the occurrence of symmetry breaking in the hole doped high cuprates. The sym…
Functional Schrödinger Representations of Holstein-Primakoff Boson and Slave-Boson Theories for Heisenberg Antiferromagnets
Sul-Ah Ahn, Kwangyl Park, Sung-Ho Suck Salk
We present functional Schrödinger representations of Holstein-Primakoff boson and slave-boson theories for the Heisenberg Hamiltonian and the Hamiltonian respectively. Based…
