Transcendental properties of entropy-constrained sets
Vjosa Blakaj, Michael M. Wolf
For information-theoretic quantities with an asymptotic operational characterization, the question arises whether an alternative single-shot characterization exists, possibly inclu…
Stacking-dependent exciton multiplicity in WSe bilayers
Zhijie Li, Jonathan Förste, Kenji Watanabe +6
Twisted layers of atomically thin two-dimensional materials realize a broad range of novel quantum materials with engineered optical and transport phenomena arising from spin and v…
Magnetic field robust high quality factor NbTiN superconducting microwave resonators
Manuel Müller, Thomas Luschmann, Andreas Faltermeier +13
We systematically study the performance of compact lumped element planar microwave (NbTiN) resonators operating at 5 GHz in external in-plane magnetic fi…
Pairing patterns in polarized unitary Fermi gases above the superfluid transition
Felipe Attanasio, Lukas Rammelmüller, Joaquín E. Drut +1
We non-perturbatively study pairing in the high-temperature regime of polarized unitary two-component Fermi gases by extracting the pair-momentum distribution and shot-noise correl…
Influence of low-energy magnons on magnon Hanle experiments in easy-plane antiferromagnets
Janine Gückelhorn, Akashdeep Kamra, Tobias Wimmer +5
Antiferromagnetic materials host pairs of spin-up and spin-down magnons which can be described in terms of a magnonic pseudospin. The close analogy between this magnonic pseudospin…
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…
The spectral gap of a fractional quantum Hall system on a thin torus
Simone Warzel, Amanda Young
We study a fractional quantum Hall system with maximal filling in the thin torus limit. The corresponding Hamiltonian is a truncated version of Haldane's pseudopotential…
Cluster expansions: Necessary and sufficient convergence conditions
Sabine Jansen, Leonid Kolesnikov
We prove a new convergence condition for the activity expansion of correlation functions in equilibrium statistical mechanics with possibly negative pair potentials. For non-negati…
Snapshot-based detection of -Laughlin states: coupled chains and central charge
Felix A. Palm, Sam Mardazad, Annabelle Bohrdt +2
Experimental realizations of topologically ordered states of matter, such as fractional quantum Hall states, with cold atoms are now within reach. In particular, optical lattices p…
Optical signatures of periodic magnetization: the moiré Zeeman effect
Alex Gómez Salvador, Clemens Kuhlenkamp, Livio Ciorciaro +2
Detecting magnetic order at the nanoscale is of central interest for the study of quantum magnetism in general, and the emerging field of moiré magnets in particular. Here, we anal…
Scaling collapse of longitudinal conductance near the integer quantum Hall transition
E. J. Dresselhaus, B. Sbierski, I. A. Gruzberg
Within the mature field of Anderson transitions, the critical properties of the integer quantum Hall transition still pose a significant challenge. Numerical studies of the transit…
Efficient Simulation of Dynamics in Two-Dimensional Quantum Spin Systems with Isometric Tensor Networks
Sheng-Hsuan Lin, Michael Zaletel, Frank Pollmann
We investigate the computational power of the recently introduced class of isometric tensor network states (isoTNSs), which generalizes the isometric conditions of the canonical fo…
Quantitative functional renormalization for three-dimensional quantum Heisenberg models
Nils Niggemann, Johannes Reuther, Björn Sbierski
We employ a recently developed variant of the functional renormalization group method for spin systems, the so-called pseudo Majorana functional renormalization group, to investiga…
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…
Optimal Thresholds for Fracton Codes and Random Spin Models with Subsystem Symmetry
Hao Song, Janik Schönmeier-Kromer, Ke Liu +3
Fracton models provide examples of novel gapped quantum phases of matter that host intrinsically immobile excitations and therefore lie beyond the conventional notion of topologica…
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…
Entropy decay for Davies semigroups of a one dimensional quantum lattice
Ivan Bardet, Ángela Capel, Li Gao +3
Given a finite-range, translation-invariant commuting system Hamiltonians on a spin chain, we show that the Davies semigroup describing the reduced dynamics resulting from the join…
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…

Shabir Barzanjeh, André Xuereb, Simon Gröblacher +3
The ability to control the motion of mechanical systems through its interaction with light has opened the door to a plethora of applications in fundamental and applied physics. Wit…
Tunable gigahertz dynamics of low-temperature skyrmion lattice in a chiral magnet
Oscar Lee, Jan Sahliger, Aisha Aqeel +4
Recently, it has been shown that the chiral magnetic insulator CuOSeO hosts skyrmions in two separated pockets in temperature and magnetic field phase space. It has also be…
