... Now in fact this is the full answer. The reason is that any higher terms of order n ≥ 5 can rewritten in terms of lower order terms. Let us imagine writing any given polynomial interaction in terms of Lz , and L± = Lx ± iLy . By commuting these around, we can always eliminate pairs of L+ and L− in f ...

Ultracold Bosons in a Tilted Multilevel Double
... Recently, Bose-Einstein condensates (BECs) in doublewell potentials have been the subject of diverse and exciting research. For instance, such systems can be used to search for deviations from Newtonian gravity at small distances [1,2] and to store and retrieve optical information [3]. Interest in t ...

Second Order Phase Transitions
... Now the behavior of f (ρ, T ) is rather different, as in Fig. 2a. At high temperatures there is a single minimum at ρ = 0 corresponding to the liquid phase. As the temperature is lowered a second minimum develops, but at a free energy that remains higher than the liquid. Only at Tm does the new free ...

Quantum Dynamics
... The three pictures of quantum dynamics are the Schrödinger picture, the Heisenberg picture, and the Interaction picture (also called the Dirac picture). They are all equivalent vector space formulations of quantum mechanics, based on different ”pictures” of how the system is evolving in time, each h ...

In the chiral limit, we found many nodal solutions, which could be interpreted as vacuum excitations. Armed with these solutions, we use the Kubo formula and calculate the filling factor for the ze ...
