A formalism is introduced to describe a number of physical processes that may\nbreak down the coherence of a matter wave over a characteristic length scale l.\nIn a second-quantized description, an appropriate master equation for a set of\nbosonic "modes" (such as atoms in a lattice, in ...
regular distortion through spacetime. Some waves, calledelectromagnetic waves, can travel through a vacuum, or a space void of matter. Some waves, calledmechanical waves, require amediumto propagate. A medium is a collection of particles that is capable of transferring energy. Examples of mediums...
Learn the 4 states of matter: solid, liquid, gas, and plasma. Review characteristics and examples, and discover the most common state of matter in...
and therefore, it transfers energy from one point to the other in a medium. Amechanical waveis generated when the matter is disturbed, and a source of energy is required to initiate a mechanical wave. A mechanical wave needs a medium to propagate, i.e. these waves can not travel through ...
Oscillations & Waves Covering oscillatory motion from pendulums to electromagnetic waves, Wolfram|Alpha supports a wide range of formulas, equations and computations to cover the physics of oscillations and waves. Find the properties of mechanical waves, play sound waves and calculate the motion of ...

Energy, like matter, consists of discrete units -- as opposed to a continuous wave. Elementary particles of energy and matter, depending on the conditions, might behave like particles or waves. The movement of elementary particles is inherently random and, thus, unpredictable. ...
Weak Nonlinear Matter Waves in a Trapped Spin-1 Condensates The dynamics of the weak nonlinear matter solitary waves in a spin-1 condensates with harmonic externalpotential are investigated analytically by a perturb... 蔡宏强,杨树荣,薛具奎,... - 《Communications in Theoretical Physics》 被引量: ...
Waves do transfer energy from one point to another, without transporting the matter or the medium itself. What is vibration and examples? Vibration is the repeated back-and-forth motion of a particle when displaced from its equilibrium position. It exhibits a periodic or repetitive motion at ...
This lesson will discuss how waves transfer energy and the different types of energy that are moved through waves. This lesson will also discuss how waves are measured, and where they are found in the physical world. Ocean waves transfer energy, not matter....
