Spectral signatures of hidden order and hidden quantum critical points
Reja H. Wilke, Henning Schlömer, Sebastian Paeckel +2
Hidden-order phases elude the conventional Ginzburg-Landau framework: although they spontaneously break symmetry, their order remains invisible to standard local two-point correlat…
Interferometric braiding of non-Abelian anyons
Francesco Debortoli, Fabian Grusdt
The manipulation of non-Abelian anyons is a foundational ingredient for topological quantum computing and underlies topologically protected quantum memories. Here we analyze a quan…
Weyl superconductivity from Feshbach resonance in the three-dimensional repulsive Hubbard model
Taekyoung Kim, Pit Bermes, Giorgia A. Busin +1
Motivated by the first experimental realization of the antiferromagnetic phase transition in the three-dimensional Fermi-Hubbard model, we present a theoretical study of the model'…
Effective theory of the hidden-order pseudogap phase in a doped antiferromagnet
Gaia De Paciani, Gesa Dünnweber, Johannes Poersch +3
The microscopic origin of the pseudogap phase constitutes a longstanding puzzle related to the emergence of high-temperature superconductivity in cuprate materials. In this work, w…
Anyon-Impurity Bound States in Quantum-Engineered Fractional Chern Insulators
Botao Wang, Amit Vashisht, Felix A. Palm +3
Mobile impurities provide a powerful means of probing correlated and topological quantum matter, through their dressing by the surrounding medium and the practical probes granting…
Majorana physics in a Luttinger liquid with attractive interactions
Francesco Debortoli, Nitya Cuzzuol, Luca Barbiero +1
Majorana zero modes are the hallmark of topological superconductivity. In one-dimensional systems, these zero modes are usually introduced in the context of gapped, mean-field mode…
A Pfaffian quantum Hall state of ultracold bosons
Joyce Kwan, Perrin Segura, Yanfei Li +7
Fractional quantum Hall states are a cornerstone of topological physics, hosting fractionally charged quasiparticles with exotic statistics that promise to enable topologically pro…
Distance learning from projective measurements as an information-geometric probe of many-body physics
Oleksii Malyshev, Simon M. Linsel, Fabian Grusdt +3
The ability of modern quantum simulators--both digital and analogue--to generate large ensembles of single-shot projective "snapshots" has opened a data-rich avenue for the study o…
Two-channel physics in a lightly doped antiferromagnetic Mott insulator revealed by two-hole spectroscopy
Pit Bermes, Sebastian Paeckel, Annabelle Bohrdt +2
Understanding pairing in the strong-coupling regime of doped Mott insulators remains an open problem in the context of cuprate superconductors. We perform ultra-high resolution num…
Realizing the Emery Model in Optical Lattices for Quantum Simulation of Cuprates and Nickelates
Hannah Lange, Liyang Qiu, Robin Groth +7
The microscopic origin of high-temperature superconductivity in cuprates remains one of the central open questions in condensed matter physics. Growing experimental and theoretical…
Matter-induced plaquette terms in a lattice gauge theory
Matjaž Kebrič, Fabian Döschl, Umberto Borla +4
Lattice gauge theories (LGTs) provide a powerful framework for studying confinement, topological order, and exotic quantum matter. In particular, the paradigmatic phenomenon of con…
Protocols for a many-body phase microscope: From coherences and d-wave superconductivity to Green's functions
Christof Weitenberg, Luca Asteria, Ola Carlsson +2
Quantum gas microscopes probe quantum many-body lattice states via projective measurements in the occupation basis, enabling access to various density and spin correlations. Phase…
Simulating superconductivity in mixed-dimensional -- bilayers with neural quantum states
Hannah Lange, Ao Chen, Antoine Georges +3
Motivated by the recent discovery of superconductivity in the bilayer nickelate LaNiO (LNO) under pressure, we study a mixed-dimensional (mixD) bilayer -$J…
