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…

Quasiparticle Energy Dispersion and Shadow Peaks in a Doped SO(5) Symmetric Ladder
Seung-Pyo Hong, Sung-Ho Suck Salk
Mean field and exact diagonalization studies on the quasiparticle excitation of an SO(5) symmetric two-leg ladder system are reported. It is shown that the energy gap in the quasip…
