Chemistry of the High-Mass Protostellar Molecular Clump IRAS 16562-3959Apr 18 2018May 24 2018We present molecular line observations of the high-mass molecular clump IRAS 16562$-$3959 taken at 3 mm using the Atacama Large Millimeter/submillimeter Array (ALMA) at 1.$\!\!^{\prime\prime}$7 angular resolution ($0.014$ pc spatial resolution). This ... More

State space modelling and data analysis exercises in LISA PathfinderJun 19 2013Jun 21 2013LISA Pathfinder is a mission planned by the European Space Agency to test the key technologies that will allow the detection of gravitational waves in space. The instrument on-board, the LISA Technology package, will undergo an exhaustive campaign of ... More

Paraelectric and Ferroelectric States in a Model for Relaxor FerroelectricsSep 09 2013We study the free energy landscape of a minimal model for relaxor ferroelectrics. Using a variational method which includes leading correlations beyond the mean-field approximation as well as disorder averaging at the level of a simple replica theory, ... More

Structural Transitions in Fibers of Bent-Core Liquid Crystals from Field-Theory Monte Carlo SimulationsJul 21 2016Aug 03 2016Fibers of bent-core liquid crystals present an internal structure of a rolled smectic layer and can be used as optical waveguides. We used a field-theoretical Monte Carlo simulation to analyze the internal configuration of such fibers as a function of ... More
