Probing quantum spin liquids with multiple quantum coherences
Lukas Homeier, Simon Linsel, Lode Pollet +1
Quantum simulators are beginning to prepare long-sought phases of matter that remain difficult to realize cleanly in materials. Yet identifying such phases remains a major challeng…
Effective theory of the hidden-order pseudogap phase in a doped antiferromagnet
Gaia De Paciani, Gesa Dünnweber, Johannes Poersch +3
The microscopic origin of the pseudogap phase constitutes a longstanding puzzle related to the emergence of high-temperature superconductivity in cuprate materials. In this work, w…
Distance learning from projective measurements as an information-geometric probe of many-body physics
Oleksii Malyshev, Simon M. Linsel, Fabian Grusdt +3
The ability of modern quantum simulators--both digital and analogue--to generate large ensembles of single-shot projective "snapshots" has opened a data-rich avenue for the study o…
ParaToric 1.0: Continuous-time quantum Monte Carlo for the toric code in a parallel field
Simon M. Linsel, Lode Pollet
We introduce ParaToric, a C++ package for simulating the toric code in a parallel field (i.e., - and -fields) at finite temperature. We implement and extend the continuous-ti…
Topology meets symmetry breaking: Hidden order, intrinsically gapless topological states and finite-temperature topological transitions
Reja H. Wilke, Henning Schlömer, Simon M. Linsel +2
Since the discovery of phase transitions driven by topological defects, the classification of phases of matter has been significantly extended beyond Ginzburg and Landau's paradigm…
Independent e- and m-anyon confinement in the parallel field toric code on non-square lattices
Simon M. Linsel, Lode Pollet, Fabian Grusdt
Kitaev's toric code has become one of the most studied models in physics and is highly relevant to the fields of both quantum error correction and condensed matter physics. Most no…
Percolation renormalization group analysis of confinement in lattice gauge theories
Gesa Dünnweber, Simon M. Linsel, Annabelle Bohrdt +1
The analytical study of confinement in lattice gauge theories (LGTs) remains a difficult task to this day. Taking a geometric perspective on confinement, we develop a real-space re…
Emergent spinon-holon Feshbach resonance in a doped Majumdar-Ghosh model
Simon M. Linsel, Ulrich Schollwöck, Annabelle Bohrdt +1
Experimental and numerical spectroscopy have revealed rich physics in antiferromagnets, in particular in frustrated and doped systems. The Majumdar-Ghosh (MG) model has an analytic…
Approximately-symmetric neural networks for quantum spin liquids
Dominik S. Kufel, Jack Kemp, DinhDuy Vu +3
We propose and analyze a family of approximately-symmetric neural networks for quantum spin liquid problems. These tailored architectures are parameter-efficient, scalable, and sig…
Percolation as a confinement order parameter in lattice gauge theories
Simon M. Linsel, Annabelle Bohrdt, Lukas Homeier +2
Lattice gauge theories (LGTs) were introduced in 1974 by Wilson to study quark confinement. These models have been shown to exhibit (de-)confined phases, yet it remains challenging…
Realistic scheme for quantum simulation of lattice gauge theories with dynamical matter in D
Lukas Homeier, Annabelle Bohrdt, Simon Linsel +3
Gauge fields coupled to dynamical matter are ubiquitous in many disciplines of physics, ranging from particle to condensed matter physics, but their implementation in large-scale q…
