Cavity-assisted preparation and detection of a unitary Fermi gas

Jean-Philippe Brantut, Victor Youri Helson, Kevin Etienne Robert Roux, Hideki Konishi

We report on the fast production and weakly destructive detection of a Fermi gas with tunable interactions in a high finesse cavity. The cavity is used both with far off-resonant light to create a deep optical dipole trap, and with near-resonant light to r ...

Laser Cooling of a Nanomechanical Oscillator to Its Zero-Point Energy

Tobias Kippenberg, Liu Qiu, Itay Shomroni

Optomechanical systems in the well-resolved-sideband regime are ideal for studying a myriad of quantum phenomena with mechanical systems, including backaction-evading measurements, mechanical squeezing, and nonclassical states generation. For these experim ...

Hidden, entangled and resonating order

Henrik Moodysson Rønnow, Gabriel Aeppli

In condensed matter systems, the atoms, electrons or spins can sometimes arrange themselves in ways that result in unexpected properties but that cannot be detected by conventional experimental probes. Several historical and contemporary examples of such h ...

Atomistic-continuum coupling of random alloys

William Curtin, Till Junge, Shankha Nag

Random alloys are multicomponent systems where the atomic type on each lattice site is independent of the atom types on any other lattice site. The fluctuations in local atomic configurations inherent to the random alloy prevents the accurate application o ...

Experimental Observation of Topological Fano Resonances for Audible Sound

Romain Christophe Rémy Fleury, Farzad Zangeneh Nejad

The Fano resonance is a widespread wave scattering phenomenon observed in many different systems, from cold atom physics, to electromagnetics, electronic circuits, and acoustics. It is characterized by a very sharp and asymmetric scattering cross-section s ...

Influence of Minor Cr-Additions to the Growth of Columnar Dendrites in Al-Zn Alloys: Influence of Icosahedral Short Range Order in the Liquid

Michel Rappaz, Güven Kurtuldu

The effect of minute Cr additions on dendritic growth directions in Al-20 wt pct Zn alloy has been investigated. As first evidenced by Gonzales and Rappaz (Metall Mater Trans A 37:2797-2806, 2006) Al-Zn alloys exhibit a Dendrite Orientation Transition (DOT ...

Universal noise in continuous transport measurements of interacting fermions

Jean-Philippe Brantut

We propose and analyze continuous measurements of atom number and atomic currents using dispersive probing in an optical cavity. For an atom-number measurement in a closed system, we relate both the detection noise and the heating rate due to measurement b ...

Atomic-scale sensing of the magnetic dipolar field from single atoms

Donat Fabian Natterer

Spin resonance provides the high-energy resolution needed to determine biological and material structures by sensing weak magnetic interactions(1). In recent years, there have been notable achievements in detecting(2) and coherently controlling(3-7) indivi ...

Entropy based fingerprint for local crystalline order

Pablo Miguel Piaggi, Michele Parrinello

We introduce a new fingerprint that allows distinguishing between liquid-like and solid-like atomic environments. This fingerprint is based on an approximate expression for the entropy projected on individual atoms. When combined with local enthalpy, this ...
