An unsupervised deep learning algorithm for single-site reconstruction in quantum gas microscopes
Alexander Impertro, Julian F. Wienand, Sophie Häfele +6
In quantum gas microscopy experiments, reconstructing the site-resolved lattice occupation with high fidelity is essential for the accurate extraction of physical observables. For…
Ultra-Sensitive Extinction Measurements of Optically Active Defects in Monolayer MoS
Florian Sigger, Ines Amersdorffer, Alexander Hötger +12
We utilize cavity-enhanced extinction spectroscopy to directly quantify the optical absorption of defects in MoS generated by helium ion bombardment. We achieve hyperspectral i…
Fast Time-Evolution of Matrix-Product States using the QR decomposition
Jakob Unfried, Johannes Hauschild, Frank Pollmann
We propose and benchmark a modified time evolution block decimation (TEBD) algorithm that uses a truncation scheme based on the QR decomposition instead of the singular value decom…
Can we observe non-perturbative vacuum shifts in cavity QED?
Rocío Sáez-Blázquez, Daniele de Bernardis, Johannes Feist +1
We address the fundamental question whether or not it is possible to achieve conditions under which the coupling of a single dipole to a strongly confined electromagnetic vacuum ca…
Cross-Platform Verification in Quantum Networks
Johannes Knörzer, Daniel Malz, J. Ignacio Cirac
Intermediate-scale quantum devices are becoming more reliable, and may soon be harnessed to solve useful computational tasks. At the same time, common classical methods used to ver…
Optimization strategies and artefacts of time-involved small angle neutron scattering experiments
Denis Mettus, Alfonso Chacon, Andreas Bauer +2
Kinetic small-angle neutron scattering provides access to the microscopic properties of mesoscale systems under slow, periodic perturbations. By interlocking the phases of neutron…
Rydberg Macrodimers: Diatomic molecules on the micrometer scale
Simon Hollerith, Johannes Zeiher
Controlling molecular binding at the level of single atoms is one of the holy grails of quantum chemistry. Rydberg macrodimers -- bound states between highly excited Rydberg atoms…
Long-Range Free Fermions: Lieb-Robinson Bound, Clustering Properties, and Topological Phases
Zongping Gong, Tommaso Guaita, J. Ignacio Cirac
We consider free fermions living on lattices in arbitrary dimensions, where hopping amplitudes follow a power-law decay with respect to the distance. We focus on the regime where t…
A Nonvanishing Spectral Gap for AKLT Models on Generalized Decorated Graphs
Angelo Lucia, Amanda Young
We consider the spectral gap question for AKLT models defined on decorated versions of simple, connected graphs G. This class of decorated graphs, which are defined by replacing al…
Lattice reconstruction in MoSe-WSe heterobilayers synthesized by chemical vapor deposition
Zhijie Li, Farsane Tabataba-Vakili, Shen Zhao +11
Vertical van der Waals heterostructures of semiconducting transition metal dichalcogenides realize moiré systems with rich correlated electron phases and moiré exciton phenomena. F…
The Thermomajorization Polytope and Its Degeneracies
Frederik vom Ende, Emanuel Malvetti
Drawing inspiration from transportation theory, in this work we introduce the notions of "well-structured" and "stable" Gibbs states and we investigate their implications for quant…
Observation of magnon bound states in the long-range, anisotropic Heisenberg model
Florian Kranzl, Stefan Birnkammer, Manoj K. Joshi +4
Over the recent years coherent, time-periodic modulation has been established as a versatile tool for realizing novel Hamiltonians. Using this approach, known as Floquet engineerin…
Few-body analogue quantum simulation with Rydberg-dressed atoms in optical lattices
Daniel Malz, J. Ignacio Cirac
Most experiments with ultracold atoms in optical lattices have contact interactions, and therefore operate at high densities of around one atom per site to observe the effect of st…
Raman scattering signatures of the strong spin-phonon coupling in the bulk magnetic van der Waals material CrSBr
Amit Pawbake, Thomas Pelini, Nathan P. Wilson +4
Magnetic excitations in layered magnetic materials that can be thinned down the two-dimensional (2D) monolayer limit are of high interest from a fundamental point of view and for a…

A full six-dimensional Born-Oppenheimer singlet potential energy surface is constructed for the reaction CaF + CaF CaF + Ca using a multireference configuration i…
Large-Scale D Gauge Theory with Dynamical Matter in a Cold-Atom Quantum Simulator
Jesse Osborne, Ian P. McCulloch, Bing Yang +2
A major driver of quantum-simulator technology is the prospect of probing high-energy phenomena in synthetic quantum matter setups at a high level of control and tunability. Here,…
Topological dynamics of adiabatic cat states
Jacquelin Luneau, Benoît Douçot, David Carpentier
We consider a quantum topological frequency converter, realized by coupling a qubit to two slow harmonic modes. The dynamics of such a system is the quantum analog of topological p…
