Emergence of spin entanglement with the pseudogap onset in the Fermi-Hubbard model
Frederic Bippus, Thomas Chalopin, Gabriele Bellomia +6
Despite decades of intense theoretical and experimental investigation, the two-dimensional Fermi-Hubbard model still resists a complete microscopic understanding. Conventional appr…
Observation of Strong-to-Weak Spontaneous Symmetry Breaking in a Dephased Fermi Gas
Si Wang, Thomas G. Kiely, Dorothee Tell +9
Symmetry-based classification of quantum phases of matter is one of the most foundational organizing principles in physics; however, an analogous framework for mixed, decohered qua…
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…
Constructing Arbitrary Coherent Rearrangements in Optical Lattices
Alexander Roth, Liyang Qiu, Timon Hilker +2
Coherent control of motional degrees of freedom of ultracold atoms in optical lattices offers a promising route towards programmable quantum dynamics with massive particles. We pro…
Phase-Sensitive Measurements on a Fermi-Hubbard Quantum Processor
Alberto R. Cavallar, Luis Escalera-Moreno, Titus Franz +4
Fermionic quantum processors are a promising platform for quantum simulation of correlated fermionic matter. In this work, we study a hardware-efficient protocol for measuring comp…
High-fidelity collisional quantum gates with fermionic atoms
Petar Bojović, Timon Hilker, Si Wang +7
Quantum simulations of electronic structure and strongly correlated quantum phases are widely regarded as among the most promising applications of quantum computing. These computat…
Observation of emergent scaling of spin-charge correlations at the onset of the pseudogap
Thomas Chalopin, Petar Bojović, Si Wang +12
In strongly correlated materials, interacting electrons are entangled and form collective quantum states, resulting in rich low-temperature phase diagrams. Notable examples include…
Local control and mixed dimensions: Exploring high-temperature superconductivity in optical lattices
Henning Schlömer, Hannah Lange, Titus Franz +7
The simulation of high-temperature superconducting materials by implementing strongly correlated fermionic models in optical lattices is one of the major objectives in the field of…
Optical superlattice for engineering Hubbard couplings in quantum simulation
Thomas Chalopin, Petar Bojović, Dominik Bourgund +4
Quantum simulations of Hubbard models with ultracold atoms rely on the exceptional control of coherent motion provided by optical lattices. Here we demonstrate enhanced tunability…
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…
