Coherent cavity networks with complete connectivity
When cavity photons couple to an optical fiber with a continuum of modes,
they usually leak out within a finite amount of time. However, if the fiber is
about one meter long and linked to a mirror, photons bounce back and forth
within the fiber on a much faster time scale. As a result, {\em dynamical
decoupling} prevents the cavity photons from entering the fiber. In this paper
we use the simultaneous dynamical decoupling of a large number of distant
cavities from the fiber modes of linear optics networks to mediate effective
cavity-cavity interactions in a huge variety of configurations. Coherent cavity
networks with complete connectivity can be created with potential applications
in quantum computing and simulation of the complex interaction Hamiltonians of
biological systems.Comment: revised version, improved analysis, 4 pages and 4 figure
Tuning the Tadpole Improved Clover Wilson Action on Coarse Anisotropic Lattices
Wilson quark action, with tadpole improved clover term added, is studied on
coarse anisotropic lattices. The bare velocity of light parameter in this
action is determined non-perturbatively using the pseudo-scalar and vector
meson dispersion relations for various values of the gauge coupling and
bare quark mass parameter .Comment: 7 pages LateX, typeset with elsart.cls, 1 figure, 5 tables (4 more
