Exotic four-quark particle spotted at Large Hadron Collider
LHC four-quark composite particle
2021/8/11
Rare tetraquark is one of dozens of non-elementary particles discovered by the accelerator, and could help to test theories about strong nuclear force.
Quantum interference in a four-level system of a $^{87}\mathrm{Rb}$ atom: Effects of spontaneously generated coherence
interference spontaneously generated coherence
2010/10/29
In this work, the effects of quantum interference and spontaneously generated coherence (SGC) are theoretically analyzed in a four level system of a $^{87}\mathrm{Rb}$ atom. For the effects of SGC, we...
Non-degenerate four-wave mixing in rubidium vapor: transient regime
Non-degenerate four-wave mixing rubidium vapor transient regime
2010/11/9
We investigate the transient response of the generated light from Four-Wave Mixing (FWM) in the diamond configuration using a step-down field excitation. The transients show fast decay times and oscil...
Effect of Warm Ionized Plasma Medium on Radiation Properties of Four Elements Microstrip Antenna Array Printed on Ferrite Substrate
Microstrip Antenna Array Ferrite Plasma Medium
2010/6/30
This paper describes theoretically the radiation properties of four element microstrip antenna array printed upon a typical ferrite substrate Ni1.062Co0.o2Fe1.948O4 in the presence of normal dc magnet...
Ginzburg-Landau equation for dynamical four-wave mixing in gain nonlinear media with relaxation
four-wave mixing Ginzburg-Landauequation Maxwell-Bloch system in optics
2010/4/7
We consider the dynamical degenerate four-wave mixing (FWM) model in a cubic nonlinear medium including both the time relaxation of the induced nonlinearity and the nonlocal coupling. The initial ten-...
A 3-D four-wing attractor and its analysis
Chaos four-wing attractor Lyapunov exponents bifurcation
2010/7/8
In this paper, several three dimensional (3-D) four-wing smooth quadratic autonomous chaotic systems are analyzed. It is shown that these systems have a number of similar features. A new 3-D continuou...
