Photon liquefaction in time
Eduardo Zubizarreta Casalengua, Elena del Valle, Fabrice P. Laussy
We provide a mechanism to imprint local temporal correlations in photon streams which have the same character as spatial correlations in liquids. Usual single-photon emitters corre…
Temperature flow in pseudo-Majorana functional renormalization for quantum spins
Benedikt Schneider, Johannes Reuther, Matías G. Gonzalez +2
We implement the temperature flow scheme first proposed by Honerkamp and Salmhofer in Phys.~Rev.~B 64, 184516 (2001) into the pseudo-Majorana functional renormalization group metho…
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…
Local readout and control of current and kinetic energy operators in optical lattices
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…
Complex Time Evolution in Tensor Networks
M. Grundner, P. Westhoff, F. B. Kugler +2
Real-time calculations in tensor networks are strongly limited in time by entanglement growth, restricting the achievable frequency resolution of Green's functions, spectral functi…
Moiré Fractional Chern Insulators III: Hartree-Fock Phase Diagram, Magic Angle Regime for Chern Insulator States, the Role of the Moiré Potential and Goldstone Gaps in Rhombohedral Graphene Superlattices
Yves H. Kwan, Jiabin Yu, Jonah Herzog-Arbeitman +3
We investigate in detail the displacement-field-tuned interacting phase diagram of layer rhombohedral graphene aligned to hBN (RG/hBN). Our calculations acc…
Spontaneous Formation of Altermagnetism from Orbital Ordering
Valentin Leeb, Alexander Mook, Libor Šmejkal +1
Altermagnetism has emerged as a third type of collinear magnetism. In contrast to standard ferromagnets and antiferromagnets, altermagnets exhibit extra even-parity wave spin order…
Quantum Optics with Rydberg Superatoms
Jan Kumlin, Christoph Braun, Christoph Tresp +3
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,…
Bridging Rokhsar-Kivelson Type and Generic Quantum Phase Transitions via Thermofield Double States
Wen-Tao Xu, Rui-Zhen Huang, Guang-Ming Zhang
The formalism of the Rokhsar-Kivelson (RK) model has been frequently used to study topological phase transitions in 2D in terms of the deformed wavefunctions, which are RK-type wav…
Scalable simulation of non-equilibrium quantum dynamics via classically optimised unitary circuits
Luke Causer, Felix Jung, Asimpunya Mitra +2
The advent of near-term digital quantum computers could offer us an exciting opportunity to investigate quantum many-body phenomena beyond that of classical computing. To make the…

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…
Doping-control of excitons and magnetism in few-layer CrSBr
Farsane Tabataba-Vakili, Huy P. G. Nguyen, Anna Rupp +9
Magnetism in two-dimensional materials reveals phenomena distinct from bulk magnetic crystals, with sensitivity to charge doping and electric fields in monolayer and bilayer van de…
Realizing Altermagnetism in Fermi-Hubbard Models with Ultracold Atoms
Purnendu Das, Valentin Leeb, Johannes Knolle +1
Altermagnetism represents a type of collinear magnetism, that is in some aspects distinct from ferromagnetism and from conventional antiferromagnetism. In contrast to the latter, s…
Bayesian Optimization for Robust State Preparation in Quantum Many-Body Systems
Tizian Blatz, Joyce Kwan, Julian Léonard +1
New generations of ultracold-atom experiments are continually raising the demand for efficient solutions to optimal control problems. Here, we apply Bayesian optimization to improv…

Yu-Jie Liu, Kirill Shtengel, Frank Pollmann
Efficient preparation of many-body ground states is key to harnessing the power of quantum computers in studying quantum many-body systems. In this work, we propose a simple method…
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…
