Can Anomalous Amplification be Attained Without Postselection? [PDF]

, 2016
We present a parameter estimation technique based on performing joint measurements of a weak interaction away from the weak-value-amplification approximation.

Femtosecond Photoionization of Atoms under Noise

, 2007
We investigate the effect of incoherent perturbations on atomic photoionization due to a femtosecond mid-infrared laser pulse by solving the time-dependent stochastic Schr\"odinger equation.

Integrated random processes exhibiting long tails, finite moments and 1/f spectra [PDF]

, 2000
A dynamical model based on a continuous addition of colored shot noises is presented. The resulting process is colored and non-Gaussian. A general expression for the characteristic function of the process is obtained, which, after a scaling assumption ...

Optimal Stochastic Enhancement of Photoionization [PDF]

, 2006
The effect of noise on the nonlinear photoionization of an atom due to a femtosecond pulse is investigated in the framework of the stochastic Schr\"odinger equation.

Phase-Coherent Dynamics of a Superconducting Flux Qubit with Capacitive-Bias Readout

, 2008
We present a systematic study of the phase-coherent dynamics of a superconducting three-Josephson-junction flux qubit. The qubit state is detected with the integrated-pulse method, which is a variant of the pulsed switching DC SQUID method.

A Bidirectional Mode-Locked Fiber Laser for Asynchronous Noise-like Pulse Generation

Photonics
We demonstrate a bidirectional fiber laser with an artificial saturable absorber of a step-index multimode fiber sandwiched by single-mode fibers. Two asynchronous noise-like pulse sequences with a repetition frequency difference of 3.16 kHz are obtained.

Generalized Rate-Code Model for Neuron Ensembles with Finite Populations

, 2006
We have proposed a generalized Langevin-type rate-code model subjected to multiplicative noise, in order to study stationary and dynamical properties of an ensemble containing {\it finite} $N$ neurons.

Comparison of filters for detecting gravitational wave bursts in interferometric detectors [PDF]

, 2002
Filters developed in order to detect short bursts of gravitational waves in interferometric detector outputs are compared according to three main points. Conventional Receiver Operating Characteristics (ROC) are first built for all the considered filters

Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

FEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐
