Density instabilities in multi-layer dipolar Fermi gases
... a self-consistent set of equations that allow to estimate the local field factor, that not only goes far beyond the RPA, by including exchange in the expression of the susceptibility, but also refines the Hubbard approximation, which excludes from G (q) the corrections to the correlation hole. The S ...

Green Function Techniques in the Treatment of Quantum Transport
... methods can deal with rather large systems due to the use of special subsets of electronic states to construct molecular Hamiltonians as well as to the approximate treatment of interactions, but often have the drawback of not being transferable. Ab initio approaches, finally, can deal in a very prec ...

Recent progress in symplectic algorithms for use in quantum systems
... Hamiltonian system is the evolution of symplectic transformation. In this sense, we say that the Hamiltonian system has a symplectic structure [1, 2]. Therefore, Ruth [3] and Feng [4] presented the symplectic algorithm for solving the Hamiltonian system, which leads to a new method for solving the H ...

If D is commutative, then, since projection matrices are self-adjoint, there must exist a unitary matrix U such that U−1 Pi U is diagonal for all 1 ≤ i ≤ v (see [57]). This means that D is unitarily equivalent to a quantum design consisting solely of ...
