... Active and passive mode locking of lasers are the main methods for obtaining ultrashort light pulses, that nowadays can reach the few femtosecond regime [1,2]. They are based on locking the phases of many axial (longitudinal) modes of a laser that can in certain cases span over most of the visible f ...

24 Interferometry with Macromolecules: Quantum Paradigms Tested
... based on a reduced density matrix which has been traced over the meter states. If all pointer states are sufficiently distinct, i.e. Φn|Φm 0, it can be shown that the quantum system is forced into a classical mixed state, lacking all coherence and ability to interfere. This formalism may be inter ...

Section 10.1: Curves Defined by Parametric Equations
... Also, we have seen that many curves are not defined explicitly as function (like the circle), and require different techniques in order to use calculus (implicit differentiation etc.). By realizing curves in a different way, we can avoid some of these complications. The first new way we consider is ...

Chern-Simons theory and Weyl quantization
... The representation theory of the quantum group parallels that of the Lie algebra, but it contains the deformation parameter. The Bethe Ansatz implies that quantum groups yield knot invariants (N. Reshetikhin). ...

... Since exact diagonalization of this Hamiltonian is not possible except for very small systems, we adopt the standard spin-wave approach, which is implemented in two clearly separated steps. First, we treat Eq. (1) as a classical functional i ), where the spin operators S are replaced by Ecl ≡ H ( ...

Nonperturbative quantum geometries
... The Lagrange multiplier fields, N and N a, are called, respectively, the lapse and the shift. In the classical theory they parametrize the slicing of the four manifold JCl into a family of three surfaces. A quantization of general relativity, from the hamiltonian point of view [7], would then consis ...
