In the Standard Model of particle physics, the Brout–Englert–Higgs mechanism provides mass to elementary particles. While physicists are carrying out direct studies of the Higgs boson to test this mec...
长江大学物理科学与技术学院力学课件第三章 Force。
2016年3月29日至4月1日，美国等离子体输运Task Force专题研讨会在美国科罗拉多州丹佛召开。来自中国、美国、日本等国家高校、科研单位的上百名实验与理论模拟专家学者与会。此次会议共11个大会特邀报告，56个墙报报告，设立了非线性台基湍流、高能粒子、三维效应、多尺度集成等9个工作组，各工作组共计28个口头报告。
We consider the motion of a particle in a random isotropic force field. Assuming that the force field arises from a Poisson field in R d, d ≥ 4, and the initial velocity of the parti...
BPS force balances via spin-spin interactions
BPS soliton static force balance spin quantum mechanics micro sub zero gravity field model
2014/12/22
We study two systems of BPS solitons in which spin-spin interactions are important in establishing the force balances which allow static, multi-soliton solutions to exist. Solitons in the Israel-Wilso...
Sigma exchange in the nuclear force and effective field theory
The meson particle spectrum nuclear force
2014/12/20
In the phenomenological description of the nuclear interaction an important role is traditionally played by the exchange of a scalar I=0 meson, the sigma, of mass 500–600 MeV, which however is not see...
Nuclear central force in the chiral limit
Chiral perturbation theory function quality component physical spectrum energy function
2014/12/20
Chiral perturbation theory supplemented by the Omnes function is employed to study the strength of the isoscalar central nuclear interaction, GS, in the chiral limit vs the physical case. A very large...
Ghost Force Influence of A Qusicontinuum Method in Two Dimension
Ghost Force Influence A Qusicontinuum Method Two Dimension
2012/8/7
The error caused by the ghost force is studied for a quasicontinuum method with planar interface in two dimension. For a special case, we derive an analytical expression of the error, which is exploit...
Convergence of a Force-Based Hybrid Method in Three Dimension
Convergence a Force-Based Hybrid Method Three Dimension
2012/8/7
We study a force-based hybrid method that couples atomistic model with Cauchy-Born elasticity model. We show the proposed scheme converges to the solution of the atomistic model with second order accu...
It is argued that the experimentally observed quark decay of high generations to lower generations is due to the existence of a 5th force which explicitly violates the CP symmetry. The main supporting...
Comment on "Trouble with the Lorentz law of force: Incompatibility with special relativity and momentum conservation"
the Lorentz law of force Incompatibility special relativity momentum conservation Optics
2012/5/29
It has been recently argued [arXiv:1205.0096] that the Lorentz force is incompatible with Special Relativity and should be amended in the presence of magnetization and polarization in order to avoid a...
Does Lorentz Force Law Contradict the Principle and Theories of Relativity for Uniform Linear Motion?
Lorentz Force Law Principle and Theories of Relativity Uniform Linear Motion Classical Physics
2012/5/29
I show that no force or torque is generated in cases involving a charge and a magnet with their relative velocity zero, in any inertial frame of reference. A recent suspicion of an anomalous torque an...
Trouble with the Lorentz law of force: Incompatibility with special relativity and momentum conservation
the Lorentz law of force Incompatibility special relativity momentum conservation Optics
2012/5/17
The Lorentz law of force is the fifth pillar of classical electrodynamics, the other four being Maxwell's macroscopic equations. The Lorentz law is the universal expression of the force exerted by ele...
Optical dipole force on ladder-like three-level atomic systems driven by chirped few-cycle-pulse laser fields
Optical dipole force ladder-like three-level atomic systems chirped few-cycle-pulse laser fields Optics
2012/5/17
We report a study on the optical dipole force in a ladder like three level atomic systems in the context of coherent population transfer with the chirped few-cycle-pulse laser fields. The phenomenon o...
State Feedback Control for Adjusting the Dynamic Behavior of a Piezoactuated Bimorph Atomic Force Microscopy Probe
State Feedback Control Dynamic Behavior Piezoactuated Bimorph Atomic Microscopy Probe Atomic Physics
2012/4/24
We adjust the transient dynamics of a piezo-actuated bimorph Atomic Force Microscopy (AFM) probe using a state feedback controller. This approach enables us to adjust the quality factor and the resona...
