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…
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…
Scalable Bell inequalities for graph states of arbitrary prime local dimension and self-testing
Rafael Santos, Debashis Saha, Flavio Baccari +1
Bell nonlocality -- the existence of quantum correlations that cannot be explained by classical means -- is certainly one of the most striking features of quantum mechanics. Its ra…
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…
Universal equation of state for wave turbulence in a quantum gas
Lena H. Dogra, Gevorg Martirosyan, Timon A. Hilker +6
Boyle's 1662 observation that the volume of a gas is, at constant temperature, inversely proportional to pressure, offered a prototypical example of how an equation of state (EoS)…
Tomography of Feshbach Resonance States
Baruch Margulis, Karl P. Horn, Daniel M. Reich +8
Feshbach resonances are fundamental to interparticle interactions and become particularly important in cold collisions with atoms, ions, and molecules. Here we present the detectio…
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…
Variational theory of angulons and their rotational spectroscopy
Zhongda Zeng, Enderalp Yakaboylu, Mikhail Lemeshko +2
The angulon, a quasiparticle formed by a quantum rotor dressed by the excitations of a many-body bath, can be used to describe an impurity rotating in a fluid or solid environment.…
Four-body singlet potential energy surface for reactions of calcium monofluoride
Dibyendu Sardar, Arthur Christianen, Hui Li +1
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,…
Analogue Quantum Simulation with Fixed-Frequency Transmon Qubits
Sean Greenaway, Adam Smith, Florian Mintert +1
We experimentally assess the suitability of transmon qubits with fixed frequencies and fixed interactions for the realization of analogue quantum simulations of spin systems. We te…
Impurity-induced pairing in two-dimensional Fermi gases
Ruipeng Li, Jonas von Milczewski, Atac Imamoglu +2
We study induced pairing between two identical fermions mediated by an attractively interacting quantum impurity in two-dimensional systems. Based on a Stochastic Variational Metho…
Photons are lying about where they have been, again
Gregory Reznik, Carlotta Versmold, Jan Dziewior +5
Bhati and Arvind [Phys. Lett. A, 127955 (2022)] recently argued that in a specially designed experiment the timing of photon detection events demonstrates photon presence at a loca…
Yang-Lee Zeros, Semicircle Theorem, and Nonunitary Criticality in Bardeen-Cooper-Schrieffer Superconductivity
Hongchao Li, Xie-Hang Yu, Masaya Nakagawa +1
Yang and Lee investigated phase transitions in terms of zeros of partition functions, namely, Yang-Lee zeros [Phys. Rev. 87, 404 (1952); Phys. Rev. 87, 410 (1952)]. We show that th…
Spin density wave, Fermi liquid, and fractionalized phases in a theory of antiferromagnetic metals using paramagnons and bosonic spinons
Alexander Nikolaenko, Jonas von Milczewski, Darshan G. Joshi +1
The pseudogap metal phase of the hole-doped cuprates can be described by small Fermi surfaces of electron-like quasiparticles, which enclose a volume violating the Luttinger relati…
Ultracold Sticky Collisions: Theoretical and Experimental Status
Roman Bause, Arthur Christianen, Andreas Schindewolf +2
Collisional complexes, which are formed as intermediate states in molecular collisions, are typically short-lived and decay within picoseconds. However, in ultracold collisions inv…
The - magnetic quadrupole transition in neutral strontium
J. Trautmann, D. Yankelev, V. Klüsener +3
We present a detailed investigation of the ultranarrow magnetic-quadrupole - transition in neutral strontium and show how it can be made accessi…
Finding the ground state of a lattice gauge theory with fermionic tensor networks: a demonstration
