Antiferromagnetism and chiral-d wave superconductivity in a honeycomb lattice close to Mott state
Chien-Peng Ho, Khee-Kyun Voo
The antiferromagnetism (AFM) and chiral-d wave superconductivity (SC) in a honeycomb lattice close to an antiferromagnetic (AF) Mott state at half band filling are studied with a t…
Dimensionality reduction in translational noninvariant wave guides
Khee-Kyun Voo
A scheme to reduce translational noninvariant quasi-one-dimensional wave guides into singly or multiply connected one-dimensional (1D) lines is proposed. It is meant to simplify th…
Localized states in the continuum in low-dimensional systems
Khee-Kyun Voo, C. S. Chu
It is shown in this paper that for open systems, states which are localized in space, discrete in energy, and embedded in the continuum of extended states, can be sustained by low-…
An Alternative Interpretation of the Magnetic Penetration Depth Data on Pr(2-x)Ce(x)CuO(4-y) and La(2-x)Ce(x)CuO(4-y)
Khee-Kyun Voo, Wen Chin Wu
We have revisited the magnetic penetration depth data on the electron-doped cuprates Pr(2-x)Ce(x)CuO(4-y) and La(2-x)Ce(x)CuO(4-y). It is proposed that the transition between the n…
Connecting wave functions at a three-leg junction of one-dimensional channels
Khee-Kyun Voo, Shu-Chuan Chen, Chi-Shung Tang +1
We propose a scheme to connect the wave functions on different one-dimensional branches of a three-leg junction (Y-junction). Our scheme differs from that due to Griffith [Trans. F…
Phases and Density of States in a Generalized Su-Schrieffer-Heeger Model
Khee-Kyun Voo, Chung-Yu Mou
Self-consistent solutions to a generalized Su-Schrieffer-Heeger model on a 2-dimensional square lattice are investigated. Away from half-filling, spatially inhomogeneous phases are…
