Stability of the Kink State in a Stack of Intrinsic Josephson Junctions (2009)
A new dynamic state characterized by $(2m_l+1)\pi$ static phase kink with integers $\{m_l\}$ is proposed recently in a stack of inductively coupled Josephson junctions. In the present paper, the...
A new family of dynamic states are found in a stack of inductively coupled intrinsic Josephson junctions in the absence of an external magnetic field. In this state, $(2m_l+1)\pi$ phase kinks with...
In a recent Letter, Tachiki \emph{et al.} argued that the dynamic state of superconductivity phase in multi junctions characterized by $\pm\pi$ kinks is hard to realize from an energetic point of...
Effects of Pressure on the Electronic and Structural Properties of LaOFeAs (2009)
We studied the pressure effects on the electronic and structural properties of LaOFeAs by first-principles calculations. For the anti-ferromagnetic (AFM) phase with stripe- like aligned Fe spins, the...
Cavity phenomena in mesas of cuprate high-$T_c$ superconductors under voltage bias (2009)
Modeling a single crystal of cuprate high-$T_c$ superconductor, such as $\rm{Bi_2Sr_2CaCu_2O_{8+\delta}}$, as a stack of intrinsic Josephson junctions, we formulate explicitly the cavity phenomenon...
Creep motions of flux lines in type II superconductors with point-like defects (2009)
Luo, Meng-Bo, Hu, Xiao, Vinokur, Valerii
We simulated the creep motions of flux lines subject to randomly distributed point-like pinning centers. It is found that at low temperatures, the pinning barrier $U$ defined in the Arrhenius-type...
Ferromagnetism in armchair graphene nanoribbon (2009)
Lin, Hsiu-Hau, Hikihara, Toshiya, Jeng, Horng-Tay, Huang, Bor-Luen, Mou, Chung-Yu, Hu, Xiao
Due to the weak spin-orbit interaction and the peculiar relativistic dispersion in graphene, there are exciting proposals to build spin qubits in graphene nanoribbons with armchair boundaries....
Reorienting the profession: Chinese architectural transformation between 1949 and 1959 (2009)
This dissertation examines changes in China's architectural profession between 1949 and 1959, the first decade of the communist regime. This dissertation explores the political impacts on the...
Ethyl 2-amino-4-(3-chlorophenyl)-5,10-dioxo-5,10-dihydro-4H-benzo[g]chromene-3-carboxylate (2009)
Xiao Hu, Song Lei, Chang-Sheng Yao
The title molecule, C22H16ClNO5, was obtained by the reaction of (E)-ethyl 3-(3-chlorophenyl)-2-cyanoacrylate and 2-hydroxynaphthalene-1,4-dione catalysed by triethylamine in ethanol. In the crystal...
Phase Dynamics in Intrinsic Josephson Junctions and its Electrodynamics (2008)
We present a theoretical description of the phase dynamics and its corresponding electrodynamics in a stack of inductively coupled intrinsic Josephson junctions of layered high-$T_c$ superconductors...
