The Quantum Channels of the Compton Scattering of an Entangled Pair of Photons
Chih-Yu Chen, C. D. Hu, Yeu Chung Lin
The Compton scattering of an entangled pair of photons is studied. Using the resulting reduced density matrix, we demonstrate how to derive the Kraus operators for the interaction…
Natural Negative-Refractive-Index Materials
Chih-Yu Chen, Ming-Chien Hsu, C. D. Hu +1
Our calculation shows that negative refractive index (NRI), which was known to exist only in metamaterials in the past, can be found in Dirac semimetals (DSM). Electrons in DSM hav…
Modular and Landen transformation between two kinds of separable solutions of Sine Gordon equation in N=2
Nan-Hong Kuo, C. D. Hu
In this article, we study on the separable N=2 solutions of Sine Gordon equation. From the original symmetry,we get two kinds of N=2 separable solutions. we find these two kinds ar…
Nonmagnetic impurity perturbation to the quasi-two-dimensional quantum helimagnet LiCu2O2
H. C. Hsu, J. -Y. Lin, W. L. Lee +6
A complete phase diagram of Zn substituted quantum quasi-two-dimensional helimagnet LiCu2O2 has been presented. Helical ordering transition temperature (T_h) of the original LiCu2O…
Quantum critical surface of the zigzag spin chain under magnetic field: Application to superconducting quantum dots
Meihua Chen, Sujit Sarkar, C. D. Hu
We analyze the exact ground state of XXZ zigzag spin chain with applied magnetic field and find the quantum critical surface. Using the theorem of positive semi-definite matrix, we…
Long Range orders in multiferroics
C. D. Hu
We proposed that in multiferroics there exists a third long range order besides the electric polarization and magnetic order. This long range order reduces the symmetry of the spat…
