A Quantum Ruler for Magnetic Deflectometry

Abstract

Matter-wave near-field interference can imprint a nano-scale fringe pattern onto a molecular beam, which allows observing its shifts in the presence of even very small external forces. Here we demonstrate quantum interference of the pre-vitamin 7-dehydrocholesterol and discuss the conceptual challenges of magnetic deflectometry in a near-field interferometer as a tool to explore photochemical processes within molecules whose center of mass is quantum delocalized.

Matter wave interferometry: Exploring the importance of the internal molecular properties

Sandra Eibenberger, Stefan Gerlich, Mathias Tomandl +5 more

We discuss new de Broglie coherence experiments in a near-field molecule interferometer with a variety of large organic molecules. While de Broglie coherence is to first order only associated with the center-of-mass motion of the diffracted particle, we here investigate the question as to which extent the internal molecular property is relevant for, compatible with or detrimental for maintaining coherence in the translational degree of freedom. External perturbations, such as inhomogeneous external electric fields, may influence the delocalized molecules inside the matter wave interferometer and they allow us to access the molecular polarizabilities, permanent or even fluctuating electric dipole moments. We extract information about the molecular states from the interference phase shifts as well as from the observed dephasing in a Kapitza-Dirac Talbot-Lau-Stark-deflectometer. We discuss the relevance of our experiments with regard to both molecule metrology and the foundations of quantum mechanics, i.e. the preservation of coherence for highly complex particles in external fields.

Colloquium : Quantum interference of clusters and molecules

Klaus Hornberger, Stefan Gerlich, Philipp Haslinger +2 more

Recent progress and future prospects of matter-wave interferometry with complex organic molecules and inorganic clusters are reviewed. Three variants of a near-field interference effect, based on diffraction by material nanostructures, at optical phase gratings, and at ionizing laser fields are considered. The theoretical concepts underlying these experiments and the experimental challenges are discussed. This includes optimizing interferometer designs as well as understanding the role of decoherence. The high sensitivity of matter-wave interference experiments to external perturbations is demonstrated to be useful for accurately measuring internal properties of delocalized nanoparticles. The prospects for probing the quantum superposition principle are investigated in the limit of high particle mass and complexity.

Perspectives for quantum interference with biomolecules and biomolecular clusters

P Geyer, Uĝur Sezer, Jonas Rodewald +6 more

Modern quantum optics encompasses a wide field of phenomena that are either related to the discrete quantum nature of light, the quantum wave nature of matter or light-matter interactions.We here discuss new perspectives for quantum optics with biological nanoparticles.We focus in particular on the prospects of matter-wave interferometry with amino acids, nucleotides, polypeptides or DNA strands.We motivate the challenge of preparing these objects in a 'biomimetic' environment and argue that hydrated molecular beam sources are promising tools for quantum-assisted metrology.The method exploits the high sensitivity of matter-wave interference fringes to dephasing and shifts in the presence of external perturbations to access and determine molecular properties.

Designing experiments which delocalize ever more complex and more massive particles requires a quantitative assessment of new interferometer configurations.Here, we introduce a figure of merit which quantifies the difference between a genuine quantum interference pattern and a classical shadow and use it to compare a number of near-field interferometer schemes.This allows us to identify the most promising setups for future tests of the quantum superposition principle, and to discuss the perspectives of interferometry with complex molecules and clusters.

Universal matter-wave interferometry as a sensor in atomic physics and physical chemistry

Yaakov Y. Fein, Stefan Gerlich, Armin Shayeghi +5 more

We review the concept of matter-wave assisted molecule metrology and present the most recent experiments which exploit the capability of universal matter-wave interferometers to measure forces as small as 10-26 N via shifts of the interference fringes in the presence of well-controlled fields. This technique allows us to compare, in the same instrument, a variety of electronic and magnetic properties for a large range of atoms and molecules. We exemplify this here with precision measurements of the static polarizability of cesium atoms and the fullerenes C60 and C70 as well as dynamically-induced susceptibilities of tailored tripeptides. We also present measurements of magnetic properties such as the diamagnetic susceptibility of ground-state atoms and aromatic and non-aromatic hydrocarbons.
