Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Finite-time singularity formations for the Landau-Lifshitz-Gilbert equation in dimension two
Landau–Lifshitz–Gilbert 二维 有限时间 奇点形成
2023/4/19
Landau-Lifshitz-Gilbert equation (LLG) describes magnetization of ferromagnets. In this paper, we consider the singularity formation of LLG from R^2 to S^2. For any prescribed N distinct points q^{j} ...
Time-lapse electrical resistivity anomalies due to contaminant transport around landfills
landfill hydrogeological modeling salinity resistivity geophysical forward and inverse modeling
2015/9/2
The extent of landfill leachate can be delineated by geo-electrical imaging as a response to the varying electrical
resistivity in the contaminated area. This research was based on a combination of h...
3D magnetic domains imaged for the first time（图）
3D magnetic the magnetic moments magnetic domains
2011/1/21
Physicists in Europe are the first to obtain 3D images of magnetic domains – regions within a material in which all the magnetic moments point in the same direction. While 2D magnetic domains on surfa...
Geodesics of electrically and magnetically charged test particles in the Reissner-Nordström space-time: analytical solutions
Geodesics of electrically magnetically charged test particles
2010/12/20
We present the full set of analytical solutions of the geodesic equations of charged test particles in the Reissner-Nordstr¨om space-time in terms of the Weierstraß }, and elliptic functions...
Time-dependent current density functional theory on a lattice
Time-dependent current density functional theory lattice
2010/11/22
A rigorous formulation of time-dependent current density functional theory (TDCDFT) on a
lattice is presented. The density-to-potential mapping and the V-representability problems are
reduced to a s...
Time-optimal CNOT between indirectly coupled qubits in a linear Ising chain
Time-optimal CNOT indirectly coupled qubits linear Ising chain
2010/10/21
We give analytical solutions for the time-optimal synthesis of entangling gates between indirectly coupled qubits 1 and 3 in a linear spin chain of three qubits subject to an Ising Hamiltonian interac...
Domain wall motion in ferromagnetic nanowires driven by arbitrary time-dependent fields: An exact result
Domain wall motion magnetic domain walls
2010/4/2
We address the dynamics of magnetic domain walls in ferromagnetic nanowires under the influence of external time-dependent magnetic fields. We report a new exact spatiotemporal solution of the Landau-...
Time-Fractional KdV Equation for the plasma in auroral zone using Variational Methods
Korteweg-de Vries Variational Methods auroral zone
2010/4/2
The reductive perturbation method has been employed to derive the Korteweg-de Vries (KdV) equation for small but finite amplitude electrostatic waves. The Lagrangian of the time fractional KdV equatio...
Time-like proton form factor measurement with PANDA
electromagnetic form factors nuclear structure FAIR PANDA
2009/11/24
The electromagnetic probe is an excellent tool to investigate the structure of the nucleon. The nearly 4π detector PANDA, will allow to make a precise determination of the electromagnetic form factors...
Time Ordering Effects on Hydrogen Zeeman-Stark Line Profiles in Low-Density Magnetized Plasmas
Time Ordering Low-Density Magnetized Plasmas Hydrogen
2009/9/4
Stark broadening of hydrogen lines is investigated in low-density magnetized plasmas, at typical conditions of magnetic fusion experiments. The role of time ordering is assessed numerically, by using ...
