Semiclassical approximation of excitations in spin-1 Heisenberg antiferromagnets
... The ground state of the Hamiltonian is characterized by l = 0 at each site. The first excited state is l = 1 at a single site. This can be treated as a particle which hops around the lattice from one site to the other. Hence we obtain a N − f old degenerate first excited state. We now include the pe ...

Eavesdropping of two-way coherent-state quantum cryptography via gaussian quantum cloning machines

This measurement can be seen as a further Gaussian additive channel at Bob’s site, which(9) gives a Gaussian noise equal to 1 for each quadrature. Thus, according ...
