Superparamagnetic clustering of data.

The physical aspects of a recently introduced method for data clustering are considered in detail. This method is based on an inhomogeneous Potts model; no assumption concerning the underlying… Expand

- 1 March 1994

A general theory of quantum-limited feedback for continuously monitored systems is presented. Two approaches are used, one based on quantum measurement theory and one on Hamiltonian system-bath… Expand

Quantum theory of optical feedback via homodyne detection.

We present a quantum theory of feedback in which the homodyne photocurrent alters the dynamics of the source cavity. To the nonlinear stochastic (Ito) evolution of the conditioned system state we add… Expand

Quantum theory of field-quadrature measurements.

The quantum effects on a cavity mode of the electromagnetic field caused by measuring one of its quadrature components is analyzed. We consider three measurement schemes: an intracavity… Expand

Gravitational-radiation damping of compact binary systems to second post-Newtonian order.

The rate of gravitational-wave energy loss from inspiralling binary systems of compact objects of arbitrary mass is derived through second post-Newtonian (2PN) order O[(Gm/rc 2 ) 2 ] beyond the… Expand

Gravitational radiation from compact binary systems: Gravitational waveforms and energy loss to second post-Newtonian order.

We derive the gravitational waveform and gravitational-wave energy flux generated by a binary star system of compact objects (neutron stars or black holes), accurate through second post-Newtonian… Expand

Optimal states and almost optimal adaptive measurements for quantum interferometry

We derive the optimal N-photon two-mode input state for obtaining an estimate straight phi of the phase difference between two arms of an interferometer. For an optimal measurement [B. C. Sanders and… Expand

- 1 March 1995

A quantum-nondemolition (QND) measurement is one which does not disturb the quantity it measures. Any measurement can be regarded as a QND measurement followed by an additional back-action which may… Expand

Adaptive phase measurements of optical modes: Going beyond the marginal Q distribution.

- Wiseman
- Physics, Medicine
- Physical review letters
- 18 December 1995

In standard single-shot measurements of the phase of an optical mode, the phase and amplitude quadratures are jointly measured, and the latter information discarded. These techniques are consequently… Expand

Spin effects in the inspiral of coalescing compact binaries.

We derive the contributions of spin-orbit and spin-spin coupling to the gravitational radiation from coalescing binary systems of spinning compact objects. We calculate spin effects in the symmetric,… Expand
