Interaction-induced Lipkin-Meshkov-Glick model in a Bose
... collective spin system with long-rang interactions. By changing the effective magnetic field, this model has a rich phase diagram in both ground- and excited- states, independent of the systemsize [6, 7, 8, 9, 10, 11]. In quantum information it can be used to test the fundamental relation between ma ...

... there comes a point when a factor of “p” prevents us treating the integral as an inverse Fourier transform. It can be replaced by (−ih̄d/dx) which, acting on the exponential, just pulls down p. As the differential operator doesn’t itself contain p, it can be taken out of the integral.) For many part ...

There has been recent work translating the value assignment proofs into probabilistic inequalities (sometimes called Kochen-Specker inequalities), giving necessary conditions for noncontextuality [2,26]. Inequalities that do not use value-assignment restrictions but only the assumption of noncontext ...

... For finite systems, there is a variational technique to efficiently approximate such a contraction (up to lattices of 11 x 11 spins) due to Verstraete and Cirac (2004). We have developed a technique to contract the whole PEPS tensor network in the thermodynamic limit for translationally-invariant sy ...

... S CHRÖDINGER in the beginning of 1926 – by the way: during a winter ski holiday in the Swiss Alps. We point out some key aspects: • The S CHRÖDINGER equation is a linear PDE of 2nd order in space and 1st order in time! As a consequence, time dependence of stationary states is truly complex. • The li ...
