Quantum phase transitions in $d - w a v e$ superconductors

Ki-Seok Kim, Sung-Sik Lee, Jae-Hyeon Eom +1

Based on an effective Lagrangian obtained from the holon-pair boson theory of Lee and Salk [Phys. Rev. B {\bf 64}, 052501 (2001)] for high $T_{c}$ cuprates, we explore physical state…

Phase Separation in the Two-Dimensional Systems of Strongly Correlated electrons; the Role of Spin Singlet Pairs on Hole Pairing Contribution to Hole-rich Phase

Sung-Sik Lee, Sul-Ah Ahn, Sung-Ho Suck Salk

By paying attention to the hole-doped two-dimensional systems of antiferromagnetically (strongly) correlated electrons, we discuss the cause of hole-rich phase formation in associa…

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 $t - J$ Hamiltonian respectively. Based…

Geometric (Berry) phases and statistical transmutation in the two-dimensional systems of strongly correlated electrons

Seung-Pyo Hong, Sung-Ho Suck Salk

Focusing on the hole-doped two-dimensional systems of strongly correlated electrons, we examine geometric phases acquired by electronic wave functions as a result of polaron transp…

Study of Harper's Equation for the 2-D Systems of Antiferromagnetically Correlated Electrons in an External Magnetic Field

Seung-Pyo Hong, Hyeonjin Doh, Sung-Ho Suck Salk

Considering interacting (antiferromagnetically correlated) electrons, we derive a generalized Harper's equation for the square lattice of infinite size. We obtain an analytic expre…
