Mesoscopic Kondo Effect in an Aharonov-Bohm Ring
Kicheon Kang, Sung-Chul Shin
An interacting quantum dot inserted in a mesoscopic ring is investigated. A variational ansatz is employed to describe the ground state of the system in the presence of the Aharono…
Reflection Amplitudes of ADE Toda Theories and Thermodynamic Bethe Ansatz
Changrim Ahn, V. A. Fateev, Chanju Kim +2
We study the ultraviolet asymptotics in affine Toda theories. These models are considered as perturbed non-affine Toda theories. We calculate the reflection amplitudes, which relat…
Hidden Relation between Reflection Amplitudes and Thermodynamic Bethe Ansatz
Changrim Ahn, Chanju Kim, Chaiho Rim
In this paper we compute the scaling functions of the effective central charges for various quantum integrable models in a deep ultraviolet region using two independent me…
New Gauge Invariant Formulation of the Chern-Simons Gauge Theory: Classical and Quantal Analysis
Mu-In Park, Young-Jai Park
Recently proposed new gauge invariant formulation of the Chern-Simons gauge theory is considered in detail. This formulation is consistent with the gauge fixed formulation. Further…
