On the origin of energy gaps in quasicrystalline potentials
Emmanuel Gottlob, David Gröters, Ulrich Schneider
Quasicrystals, structures that are ordered yet aperiodic, defy conventional band theory, confining most studies to finite-size real-space numerics. We overcome this limitation with…
Generation of strong ultralow-phase-noise microwave fields with tunable ellipticity for ultracold polar molecules
Shrestha Biswas, Sebastian Eppelt, Christian Buchberger +6
Microwave(MW) fields with strong field strength, ultralow phase-noise and tunable polarization are crucial for stabilizing and manipulating ultracold polar molecules, which have em…
No-cost Bell nonlocality certification from quantum tomography and its applications in quantum-magic-resource witnessing
Pawel Cieslinski, Lukas Knips, Harald Weinfurter +1
Tomographic measurements are the standard tool for characterizing quantum states, yet they are usually regarded only as means for state reconstruction or fidelity measurement. Here…
Error Resilience of Fracton Codes and Near Saturation of Code-Capacity Threshold in Three Dimensions
Giovanni Canossa, Lode Pollet, Miguel A. Martin-Delgado +2
Fracton codes have been intensively studied as novel topological states of matter, yet their fault-tolerant properties remain largely unexplored. Here, we investigate the optimal t…
Refrigeration of a 1D gas of microwave photons
Lukas Schamriß, Louis Garbe, Peter Rabl
We discuss a conceptually simple scheme for cooling a one dimensional gas of microwave photons in a superconducting transmission line. By shunting one end of the transmission line…
False Vacuum Decay in Flat-Band Ferromagnets: Role of Quantum Geometry and Chiral Edge States
Fabian Pichler, Clemens Kuhlenkamp, Michael Knap
Dynamical control of quantum matter is a challenging, yet promising direction for probing strongly correlated states. Motivated by recent experiments in twisted MoTe that demon…
Programmable Assembly of Ground State Fermionic Tweezer Arrays
Naman Jain, Jin Zhang, Marcus Culemann +1
We demonstrate deterministic preparation of arbitrary two-component product states of fermionic Li atoms in an 88 optical tweezer array, achieving motional ground-state…
Optimizing the dynamical preparation of quantum spin lakes on the ruby lattice
DinhDuy Vu, Dominik S. Kufel, Jack Kemp +3
Quantum spin liquids are elusive long-range entangled states. Motivated by experiments in Rydberg quantum simulators, recent excitement has centered on the possibility of dynamical…
Development of a Modular Optically Detected Magnetic Resonance Setup for Optical Experiments in a Variable Temperature Insert
Anh Tong, Andreas Bauer, Markus Kleinhans +6
We developed an optically detected magnetic resonance (ODMR) setup designed for compatibility with a widely used, commercially available helium bath cryostat equipped with a variab…
Many-Body Entanglement in Solid-State Emitters
Emma Daggett, Christian M. Lange, Bennet Windt +23
The preparation and control of quantum states lie at the heart of quantum information science (QIS). Recent advances in solid-state quantum emitters (QEs) and nanophotonics have tr…
Non-Reciprocal Zone Boundary Magnon Propagation in CuOSeO
Tobias Weber, Niclas Heinsdorf, Michal Stekiel +3
Inelastic neutron scattering in the chiral magnet CuOSeO reveals strong non-reciprocal effects on magnon propagation at the boundary of the nuclear Brillouin zone. The non-…
Persistence of the Berezinskii-Kosterlitz-Thouless transition with long-range couplings
Luis Walther, Josef Willsher, Johannes Knolle
The Berezinskii-Kosterlitz-Thouless (BKT) transition is an archetypal example of a topological phase transition, which is driven by the proliferation of vortices. In this Letter, w…
Bounded-Error Quantum Simulation via Hamiltonian and Lindbladian Learning
Tristan Kraft, Manoj K. Joshi, William Lam +11
Analog Quantum Simulators offer a route to exploring strongly correlated many-body dynamics beyond classical computation, but their predictive power remains limited by the absence…
Excited states from local effective Hamiltonians of matrix product states and their entanglement spectrum transition
Denise Cocchiarella, Mingru Yang, Yueshui Zhang +3
Solving excited states is a challenging task for interacting systems. For one-dimensional critical systems, however, excited states can be directly accessed from the eigenvectors o…
Additional quantum many-body scars of the spin- model with Fock-space cages and commutant algebras
Sashikanta Mohapatra, Sanjay Moudgalya, Ajit C. Balram
Quantum many-body scars (QMBS) represent a mechanism for weak ergodicity breaking, characterized by the coexistence of atypical non-thermal eigenstates within an otherwise thermali…
Skeleton of isometric Tensor Network States for Abelian String-Net Models
Julian Boesl, Yu-Jie Liu, Frank Pollmann +1
We construct parametrized isometric tensor network states -- referred to as skeletons -- that allow us to explore phases of abelian topological order and can be efficiently impleme…
Interferometric Braiding of Anyons in Chern Insulators
Felix A. Palm, Nader Mostaan, Nathan Goldman +1
Coherent control and braiding of anyons remain central challenges in realizing topologically protected quantum operations. We propose a Ramsey interferometry protocol to directly a…
Perspective on Moreau-Yosida Regularization in Density-Functional Theory
Markus Penz, Michael F. Herbst, Trygve Helgaker +1
Within density-functional theory, Moreau-Yosida regularization enables both a reformulation of the theory and a mathematically well-defined definition of the Kohn-Sham approach. It…
Continuous matrix product operators for quantum fields
Erickson Tjoa, J. Ignacio Cirac
In this work we introduce an ansatz for continuous matrix product operators for quantum field theory. We show that (i) they admit a closed-form expression in terms of finite number…
Krylov Complexity Meets Confinement
Xuhao Jiang, Jad C. Halimeh, N. S. Srivatsa
In high-energy physics, confinement denotes the tendency of fundamental particles to remain bound together, preventing their observation as free, isolated entities. Interestingly,…
