Single-pixel transmission matrix recovery via 2-photon fluorescence
Shupeng Zhao, Bernhard Rauer, Lorenzo Valzania +5
Imaging at depth in opaque materials has long been a challenge. Recently, wavefront shaping has enabled significant advance for deep imaging. Nevertheless, most non-invasive wavefr…
Scattering correcting wavefront shaping for three-photon microscopy
Bernhard Rauer, Hilton B. de Aguiar, Laurent Bourdieu +1
Three-photon (3P) microscopy is getting traction due to its superior performance in deep tissues. Yet, aberrations and light scattering still pose one of the main limitations in th…
Experimental verification of the area law of mutual information in a quantum field simulator
Mohammadamin Tajik, Ivan Kukuljan, Spyros Sotiriadis +10
Theoretical understanding of the scaling of entropies and the mutual information has led to significant advances in the research of correlated states of matter, quantum field theor…
Non-invasive chemically selective energy delivery and focusing inside a scattering medium guided by Raman scattering
Bingxin Tian, Bernhard Rauer, Antoine Boniface +4
Raman scattering is a chemically selective probing mechanism with diverse applications in industry and clinical settings. Yet, most samples are optically opaque limiting the applic…
Temporal light control in complex media through the singular value decomposition of the time-gated transmission matrix
Louisiane Devaud, Bernhard Rauer, Matthias Kühmayer +4
The complex temporal behavior of an ultrashort pulse of light propagating through a multiply scattering medium can be characterized experimentally through a time-gated transmission…
Emergent Pauli blocking in a weakly interacting Bose gas
Federica Cataldini, Frederik Møller, Mohammadamin Tajik +6
The relationship between many-body interactions and dimensionality is integral to numerous emergent quantum phenomena. A striking example is the Bose gas, which upon confinement to…

We comprehensively investigate two distinct mechanisms leading to memory loss of non-Gaussian correlations after switching off the interactions in an isolated quantum system underg…
Speckle engineering through singular value decomposition of the transmission matrix
Louisiane Devaud, Bernhard Rauer, Jakob Melchard +3
Speckle patterns are ubiquitous in optics and have multiple applications for which the control of their spatial correlations is essential. Here, we report on a method to engineer s…
Decay and recurrence of non-Gaussian correlations in a quantum many-body system
Thomas Schweigler, Marek Gluza, Mohammadamin Tajik +8
Gaussian models provide an excellent effective description of many quantum many-body systems ranging from condensed matter systems all the way to neutron stars. Gaussian states are…

Mohammadamin Tajik, Bernhard Rauer, Thomas Schweigler +6
We use laser light shaped by a digital micro-mirror device to realize arbitrary optical dipole potentials for one-dimensional (1D) degenerate Bose gases of 87Rb trapped on an atom…
Nonlinear Polariton Fluids in a Flatband Reveal Discrete Gap Solitons
V. Goblot, B. Rauer, F. Vicentini +10
Phase frustration in periodic lattices is responsible for the formation of dispersionless flat bands. The absence of any kinetic energy scale makes flat band physics critically sen…
Quantum read-out for cold atomic quantum simulators
M. Gluza, T. Schweigler, B. Rauer +3
Quantum simulators allow to explore static and dynamical properties of otherwise intractable quantum many-body systems. In many instances, however, it is the read-out that limits s…

Even though the evolution of an isolated quantum system is unitary, the complexity of interacting many-body systems prevents the observation of recurrences of quantum states for al…

We experimentally study the dynamics of a degenerate one-dimensional Bose gas that is subject to a continuous outcoupling of atoms. Although standard evaporative cooling is rendere…
