Audio Watermarking over the Air With Modulated Self-Correlation
Yuan-Yen Tai, Mohamed F. Mansour
We propose a novel audio watermarking system that is robust to the distortion due to the indoor acoustic propagation channel between the loudspeaker and the receiving microphone. T…
An efficient clustering algorithm from the measure of local Gaussian distribution
Yuan-Yen Tai
In this paper, I will introduce a fast and novel clustering algorithm based on Gaussian distribution and it can guarantee the separation of each cluster centroid as a given paramet…
Strong-Correlation Derived Spin-Fermion Model for Skyrmions in MnGe
Hongchul Choi, Yuan-Yen Tai, Jian-Xin Zhu
MnGe has been reported as a candidate of three-dimensional (3D) skyrmion crystal in comparison to the two-dimensional (2D) skyrmion observed in most other B20 compounds like MnSi.…
Local charge variation enhanced spin canting of BiFeO3/La0.7Sr0.3MnO3 heterostructure
Yuan-Yen Tai, Jian-Xin Zhu
Transition-metal oxides (TMOs) exhibit many emergent phenomena ranging from high-temperature super- conductivity and giant magnetoresistance to magnetism and ferroelectricity. When…
Edge states and local electronic structure around an adsorbed impurity in a topological superconductor
Yuan-Yen Tai, Hongchul Choi, Towfiq Ahmed +2
Recently topological superconducting states has attracted a lot of interest. In this work, we consider a topo- logical superconductor with topological mirror order [1] and s$…
Phase diagram of the isovalent phosphorous-substituted 122-type iron pnictides
YuanYuan Zhao, Yuan-Yen Tai, C. S. Ting
Recent experiments demonstrated that isovalent doping system gives the similar phase diagram as the heterovalent doped cases. For example, with the phosphorous (P)-doping, the magn…
A unified description of superconducting pairing symmetry in electron-doped Fe-based-122 compounds
Bo Li, Lihua Pan, Yuan-Yen Tai +4
The pairing symmetry is examined in highly electron-doped Ba(FeCoAs) and AFeSe (with A=K, Cs) compounds, with similar crystallographic and electronic ba…
Evolution of quasiparticle states with and without a Zn-impurity in doped 122 iron pnictides
Lihua Pan, Jian Li, Yuan-Yen Tai +3
Based on a minimal two-orbital model [Tai {\it et al.}, Europhys. Lett. \textbf{103}, 67001 (2013)], which captures the canonical electron-hole-doping phase diagram of the iron-pni…
Emergent topological mirror insulator in t2g-orbital systems
Yuan-Yen Tai, Cheng-Ching Joseph Wang, Matthias J. Graf +2
The electronic band structure of iron pnictides exhibits four Dirac cones, which are due to crystal symmetry and orbital bonding orientation. This hallmark signature presents the p…
Evolution of the Fermi surface topology in doped 122 iron pnictides
Lihua Pan, Jian Li, Yuan-Yen Tai +3
Based on the minimum two-orbital model and the phase diagram recently proposed by Tai et al.\ (Europhys. Lett. \textbf{103}, 67001(2013)) for both electron- and hole-doped 122 iron…
Disorder effects in multiorbital -wave superconductors: Implications for Zn-doped BaFeAs compounds
Hua Chen, Yuan-Yen Tai, C. S. Ting +3
Recent experiments on Zn-doped 122-type iron pnictides, Ba(FeCoZn)As, are challenging our understanding of electron doping the 122s and the interplay betw…
Phase diagram of doped BaFeAs superconductor under broken symmetry
Yuan-Yen Tai, Jian-Xin Zhu, Matthias J. Graf +1
We develop a minimal multiorbital tight-binding model with realistic hopping parameters. The model breaks the symmetry of the tetragonal point group by lowering it from to $D…
Fermi surface evolution and checker-board block-spin antiferromagnetism in FeSe
Yuan-Yen Tai, Jian-Xin Zhu, Matthias J. Graf +1
We develop an effective multiorbital mean-field t-J Hamiltonian with realistic tight-binding and exchange parameters to describe the electronic and magnetic structures of iron-sele…
