Squeezing Quantum Many-Body Scars
Bennet Windt, Hannes Pichler
We develop an analytical approach for the description of quantum many-body scars in PXP models. We show that the scarred dynamics in the PXP model on a complete bipartite graph can…
Transition from a polaronic condensate to a degenerate Fermi gas of heteronuclear molecules
Marcel Duda, Xing-Yan Chen, Andreas Schindewolf +5
The interplay of quantum statistics and interactions in atomic Bose--Fermi mixtures leads to a phase diagram markedly different from pure fermionic or bosonic systems. However, inv…
Temporal entanglement, quasiparticles and the role of interactions
Giacomo Giudice, Giuliano Giudici, Michael Sonner +4
In quantum many-body dynamics admitting a description in terms of non-interacting quasiparticles, the Feynman-Vernon influence matrix (IM), encoding the effect of the system on the…
Tensor network approach to electromagnetic duality in (3+1)d topological gauge models
Clement Delcamp
Given the Hamiltonian realisation of a topological (3+1)d gauge theory with finite group , we consider a family of tensor network representations of its ground state subspace. T…
Supersymmetric Free Fermions and Bosons: Locality, Symmetry and Topology
Zongping Gong, Robert H. Jonsson, Daniel Malz
Supersymmetry, originally proposed in particle physics, refers to a dual relation that connects fermionic and bosonic degrees of freedom in a system. Recently, there has been consi…
Bright and Dark States of Light: The quantum Origin of Classical Interference
Celso J. Villas-Boas, Carlos E. Máximo, Paulo J. Paulino +2
Classical theory asserts that several electromagnetic waves cannot interact with matter if they interfere destructively to zero, whereas quantum mechanics predicts a nontrivial lig…
Symmetry Protected Topological Order in Open Quantum Systems
Caroline de Groot, Alex Turzillo, Norbert Schuch
We systematically investigate the robustness of symmetry protected topological (SPT) order in open quantum systems by studying the evolution of string order parameters and other pr…
Laser excitation of the 1s-hyperfine transition in muonic hydrogen
P. Amaro, A. Adamczak, M. Abdou Ahmed +43
The CREMA collaboration is pursuing a measurement of the ground-state hyperfine splitting (HFS) in muonic hydrogen (p) with 1 ppm accuracy by means of pulsed laser spectroscopy…
Entangling single atoms over 33 km telecom fibre
Tim van Leent, Matthias Bock, Florian Fertig +10
Heralded entanglement between distant quantum memories is the key resource for quantum networks. Based on quantum repeater protocols, these networks will facilitate efficient large…
Dynamics of atoms within atoms
S. Tiwari, F. Engel, M. Wagner +3
Recent experiments with Bose-Einstein condensates have entered a regime in which thousands of ground-state condensate atoms fill the Rydberg-electron orbit. After the excitation of…
Cross-polarized surface lattice resonances in a rectangular lattice plasmonic metasurface
M. Saad Bin-Alam, Orad Reshef, Raja Naeem Ahmad +4
Multiresonant metasurfaces could enable many applications in filtering, sensing and nonlinear optics. However, developing a metasurface with more than one high-quality-factor or hi…
Symmetries and local transformations of translationally invariant Matrix Product States
Martin Hebenstreit, David Sauerwein, Andras Molnar +2
We determine the local symmetries and local transformation properties of translationally invariant matrix product states (MPS). We focus on physical dimension and bond dimens…
Quantum-Logic Gate between Two Optical Photons with an Average Efficiency above 40%
Thomas Stolz, Hendrik Hegels, Maximilian Winter +5
Optical qubits uniquely combine information transfer in optical fibers with a good processing capability and are therefore attractive tools for quantum technologies. A large challe…
Beam steering at the nanosecond time scale with an atomically thin reflector
Trond I. Andersen, Ryan J. Gelly, Giovanni Scuri +15
Techniques to mold the flow of light on subwavelength scales enable fundamentally new optical systems and device applications. The realization of programmable, active optical syste…
Thouless Pumps and Bulk-Boundary Correspondence in Higher-Order Symmetry-Protected Topological Phases
Julian F. Wienand, Friederike Horn, Monika Aidelsburger +2
The bulk-boundary correspondence relates quantized edge states to bulk topological invariants in topological phases of matter. In one-dimensional symmetry-protected topological sys…
High-resolution 'magic'-field spectroscopy on trapped polyatomic molecules
Alexander Prehn, Martin Ibrügger, Gerhard Rempe +1
Rapid progress in cooling and trapping of molecules has enabled first experiments on high resolution spectroscopy of trapped diatomic molecules, promising unprecedented precision.…
Realizing distance-selective interactions in a Rydberg-dressed atom array
Simon Hollerith, Kritsana Srakaew, David Wei +10
Measurement-based quantum computing relies on the rapid creation of large-scale entanglement in a register of stable qubits. Atomic arrays are well suited to store quantum informat…

Active optical media leading to interaction Hamiltonians of the form represent a crucial resource for quantum optical technology. In this paper…
Exact Spectral Statistics in Strongly Localised Circuits
Bruno Bertini, Pavel Kos, Tomaz Prosen
Since the seminal work of Anderson, localisation has been recognised as a standard mechanism allowing quantum many-body systems to escape ergodicity. This idea acquired even more p…
Thermal critical dynamics from equilibrium quantum fluctuations
Irénée Frérot, Adam Rançon, Tommaso Roscilde
We show that quantum fluctuations display a singularity at thermal critical points, involving the dynamical exponent. Quantum fluctuations, captured by the quantum variance (I.…
Operator product expansion coefficients from the nonperturbative functional renormalization group
