Formation of stripes in a mixed-dimensional cold-atom Fermi-Hubbard system
Dominik Bourgund, Thomas Chalopin, Petar Bojović +8
The relation between d-wave superconductivity and stripes is fundamental to the understanding of ordered phases in cuprates. While experimentally both phases are found in close pro…
Phases of Matrix Product States with Symmetric Quantum Circuits and Symmetric Measurements with Feedforward
David Gunn, Georgios Styliaris, Tristan Kraft +1
Two matrix product states (MPS) are in the same phase in the presence of symmetries if they can be transformed into one another via symmetric short-depth circuits. We consider how…
The anomalous Floquet Anderson insulator in a continuously driven optical lattice
Arijit Dutta, Efe Sen, Jun-Hui Zheng +2
The anomalous Floquet Anderson insulator (AFAI) has been theoretically predicted in step-wise periodically driven models, but its stability under more general driving protocols has…

Alexander Impertro, Simon Karch, Julian F. Wienand +4
Quantum gas microscopes have revolutionized quantum simulations with ultracold atoms, allowing to measure local observables and snapshots of quantum states. However, measurements s…
Momentum-dependent quasiparticle properties of the Fermi polaron from the functional renormalization group
Jonas von Milczewski, Richard Schmidt
We study theoretically the lifetimes of attractive and repulsive Fermi polarons, as well as the molecule at finite momentum in three dimensions. To this end, we develop a new techn…

Quantum optics based on highly excited atoms, also known as Rydberg atoms, has cemented itself as a powerful platform for the manipulation of light at the few-photon level. The Ryd…
Feshbach hypothesis of high-Tc superconductivity in cuprates
Lukas Homeier, Hannah Lange, Eugene Demler +2
Resonant interactions associated with the emergence of a bound state constitute one of the cornerstones of modern many-body physics, ranging from Kondo physics, BEC-BCS crossover,…
Efficient Quantum Algorithm for Filtering Product States
Reinis Irmejs, Mari Carmen Bañuls, J. Ignacio Cirac
We introduce a quantum algorithm to efficiently prepare states with a small energy variance at the target energy. We achieve it by filtering a product state at the given energy wit…
Quantum wires with local particle loss: Transport manifestations of fluctuation-induced effects
Marcel Gievers, Thomas Müller, Heinrich Fröml +2
We investigate the transport properties of a quantum wire of weakly interacting fermions in the presence of local particle loss. We calculate current and conductance in this system…
Unmasking the Polygamous Nature of Quantum Nonlocality
Paweł Cieśliński, Lukas Knips, Mateusz Kowalczyk +4
Quantum mechanics imposes limits on the statistics of certain observables. Perhaps the most famous example is the uncertainty principle. Similar trade-offs also exist for the simul…
Quantum information spreading in generalised dual-unitary circuits
Alessandro Foligno, Pavel Kos, Bruno Bertini
We study the spreading of quantum information in a recently introduced family of brickwork quantum circuits that generalises the dual-unitary class. These circuits are unitary in t…
