... In the above example, the particle was able to penetrate into the classically disallowed region, though not very effectively, since the wavefunction decayed away exponentially the further you went into that region. But what if the classicaly forbidden region has only finite thickness? ...

... We observe that as the wavelength reduces, the standing wave becomes more and more particle-like, which makes sense considering what happens in the K-capture process. It is interesting to observe that an induced K-capture process is thought responsible for transforming protons to neutrons. 7 Thus it ...

In quantum theory, one may not, as in classical theory, specify both velocity and position exactly. Instead, the maximum spec ...

... In this model there is complete symmetry between the two receeding counter-worlds. They might be identified, or one might follow Stannard (Nature 211 (1966) 693-695) and Schulman (Phys Rev Letts 83 (1999) 5419) and others and imagine the that they have the opposite arrow of time. In fact setting up ...

... At the Tevatron at Fermilab, we are already exploring a new regime of energy and distance. In three years, we will start to explore much greater energies at the LHC.

Thus, in the general theory, gravity is not an independent field defined on spacetime as much as it is the curvature of spacetime itself. This will prove to be the primary stumbling block in the quantization of ...

... It is know that the representation theory of the elliptic quantum group Uq,p (g) yields a systematic construction of the integral expressions of the solutions to the face type (dynamical) elliptic q -KZ equation.

Instanton

An instanton (or pseudoparticle) is a notion appearing in theoretical and mathematical physics. An instanton is a classical solution to equations of motion with a finite, non-zero action, either in quantum mechanics or in quantum field theory. More precisely, it is a solution to the equations of motion of the classical field theory on a Euclidean spacetime.
