Effect of strong correlations on the high energy anomaly in hole- and electron-doped high-Tc superconductors
B. Moritz, F. Schmitt, W. Meevasana +8
Recently, angle-resolved photoemission spectroscopy (ARPES) has been used to highlight an anomalously large band renormalization at high binding energies in cuprate superconductors…
Novel Jeff = 1/2 Mott State Induced by Relativistic Spin-Orbit Coupling in Sr2IrO4
B. J. Kim, Hosub Jin, S. J. Moon +11
We investigated electronic structure of 5d transition-metal oxide Sr2IrO4 using angle-resolved photoemission, optical conductivity, and x-ray absorption measurements and first-prin…
The Functional Schrödinger Picture Approach to Many-Particle Systems
Chul Koo Kim, Sang Koo You
A self-contained pedagogical introduction to the functional Schrödinger picture method of many-body theory is given at a level suitable for graduate students and also for many-body…
Mesoscopic Luttinger Liquid Theory in an Aharonov-Bohm Ring
Mun Dae Kim, Sam Young Cho, Chul Koo Kim +1
A careful study on the mesoscopic PC in a Luttinger liquid ring is carried out. It is shown that discreteness plays an important role in calculating the PC caused by the magnetic f…
Ferromagnetic Fixed Point of the Kondo Model in a Luttinger Liquid
Mun Dae Kim, Chul Koo Kim, Kyun Nahm +1
The Kondo effect in a Luttinger liquid is studied using the renormalization group method. By renormalizing the boson fields, scaling equations to the second order for an arbitrary…
A variational perturbation scheme for many-particle systems in the functional integral approach
Sang Koo You, Chul Koo Kim, Kyun Nahm +1
A variational Perturbation theory based on the functional integral approach is formulated for many-particle systems. Using the variational action obtained through Jensen-Peierls' i…
Finite temperature many-particle theory of condensed matter systems in the functional Schroedinger picture
Hyun Sik Noh, Sang Koo You, Chul Koo Kim
A finite temperature many-particle theory of condensed matter systems is formulated using the functional Schroedinger picture. Using the interacting electron gas as a model system,…
