We propose a rational quantum deformed nonlocal currents in the homogeneous space SU(2)k/U(1), and in terms of it and a free boson field a representation for th
We propose a scheme for the generation of superpositions of two Bloch states for a collection of ions. In the scheme the ions are trapped in a linear potential
A parabolic-bistable potential system driven by colored noise is studied. The exact analytical expressionsof the stationary probability distribution (SPD) and t
