HiLumi News: 7.2-m-long niobium–tin quadrupole magnet manufactured at CERN reaches nominal current for the first time（图）
欧洲核子研究中心 铌锡四极杆磁铁 标称电流
2023/5/26
Another success for the HL-LHC magnet programme: after the successful endurance test of a 4.2-metre-long niobium–tin quadrupole magnet in the United States in spring 2022, the HL-LHC quadrupole’s long...
Researchers create 'time crystals' envisioned by Princeton scientists（图）
Researchers time crystals Princeton scientists
2017/3/30
Time crystals may sound like something from science fiction, having more to do with time travel or Dr. Who. These strange materials — in which atoms and molecules are arranged across space and time — ...
Discrete Parity-Time Symmetric Nonlinear Schrodinger Lattices
Lattices Parity-time Symmetry Schrodinger
2014/12/8
In this thesis we summarize the classical cases of one-dimensional oligomers and two dimensional plaquettes, respecting the parity-time (PT ) symmetry. We examine different types of solutions of such ...
Time Resolved Collective Entanglement Dynamics in Cavity Quantum Electrodynamics
Time Resolved Collective Entanglement Dynamics Cavity Quantum Electrodynamics
2012/2/27
Nonlinearity and entanglement are two important indications by which physical systems can be identified as non-classical. We study the dynamics of the resonant interaction of up to N=3 two-level syste...
Penetration of nonquantized magnetic flux through a domain-wall bend in time-reversal symmetry broken superconductors
Penetration of nonquantized magnetic flux domain-wall superconductors
2010/11/22
It has been proposed that the superconductivity of Sr2RuO4 is characterized by pairing that is
unconventional and, furthermore, spontaneously breaks time-reversal symmetry. However, one of
the key e...

2010/11/18
We show that in a turbulent ow transporting suspended sediment, the unsaturated sediment ux q(x; t) can be described by a rst-order relaxation equation.
Time reparametrization symmetry in a short-range p-spin model
Time reparametrization symmetry short-range p-spin model
2010/11/19
We explore the existence of time reparametrization symmetry in the p-spin model. Using the Martin-Siggia-Rose generating functional, we analytically probe the long-time dynamics. We perform a Renormal...
Dynamical Implications of Adjustments to Proper Time Caused by Higher Dimensions: A Note
Higher dimensions Cosmological constant Hubble’s Law Heisenberg’s relation
2010/12/21
When the proper time of general relativity is adjusted to reflect the possible existence
of higher dimensions, small dynamical effects appear in spacetime of the sort usually associated with the cosm...
Phase diffusion of a two-component Bose-Einstein condensates: exact and short-time solutions for arbitrary coherent spin state
two-component Bose-Einstein condensates arbitrary coherent spin state
2010/11/23
We investigate phase diffusion of a two-component Bose-Einstein condensates prepared initially in arbitrary coherent spin state |θ0, φ0i. Analytical expression of the phase-diffusion time is presented...
Time-dependent self-trapping of Bose-Einstein Condensates in a double-well potential
Time-dependent self-trapping Bose-Einstein Condensates double-well potential
2010/10/27
Based on the mean-field approximation and the phase space analysis, we discuss the dynamics
of Bose-Einstein condensates in a double-well potential. By applying a periodic modulation to the coupling ...

Bose-Einstein condensates space and time
2010/4/1
In this paper we present soliton solutions of two coupled nonlinear Schodinger equations modulated in the bspace and time. The approach allows us to obatin solitons with large variety of solutions dep...

In this paper, we report the effect of annealing time on the properties of copper indium diselenide CuInSe2 films. The CuInSe2 thin films have been grown at room temperature by electrochemical deposit...
For the first time, MIT scientists have observed ferromagnetic behavior in an atomic gas, addressing a decades-old question of whether it is possible for a gas to show properties similar to a magnet m...
In this paper we seek the solutions of the time dependent
Ginzburg-Landau model for type-II superconductors such that the
associated physical observables are spatially periodic with respect to
some...

2010/4/12
Developer composition type and development technique are known to influence surface and edge roughness in polymethylemethacrylate (PMMA); and it is during development, we believe, that the result is m...
