Optical Synthesis of Terahertz and Millimeter-Wave Frequencies with Discrete Mode Diode Lasers
Stephen O'Brien, Simon Osborne, David Bitauld +5
It is shown that optical synthesis of terahertz and millimeter-wave frequencies can be achieved using two-mode and mode-locked discrete mode diode lasers. These edge-emitting devic…
Canonical lossless state-space systems: Staircase forms and the Schur algorithm
Ralf L. M. Peeters, Bernard Hanzon, Martine Olivi
A new finite atlas of overlapping balanced canonical forms for multivariate discrete-time lossless systems is presented. The canonical forms have the property that the controllabil…
Balanced realizations of discrete-time stable all-pass systems and the tangential Schur algorithm
Bernard Hanzon, Martine Olivi, Ralf L. M. Peeters
In this paper, the connections are investigated between two different approaches towards the parametrization of multivariable stable all-pass systems in discrete-time. The first ap…
Memory-keeping effects and forgetfulness in the dynamics of a qubit coupled to a spin chain
T. J. G. Apollaro, C. Di Franco, F. Plastina +1
Using recently proposed measures for non-Markovianity [H. P. Breuer, E. M. Laine, and J. Piilo, Phys. Rev. Lett. {\bf 103}, 210401 (2009)], we study the dynamics of a qubit coupled…
Transport, atom blockade and output coupling in a Tonks-Girardeau gas
L. Rutherford, J. Goold, Th. Busch +1
Recent experiments have demonstrated how quantum-mechanical impurities can be created within strongly correlated quantum gases and used to probe the coherence properties of these s…
Flows of constant mean curvature tori in the 3-sphere: The equivariant case
Martin Kilian, Martin Ulrich Schmidt, Nicholas Schmitt
We present a deformation for constant mean curvature tori in the 3-sphere. We show that the moduli space of equivariant constant mean curvature tori in the 3-sphere is connected, a…
