Wigner 6j symbols with gluon lines: completing the set of 6j symbols required for color decomposition
Stefan Keppeler, Simon Plätzer, Malin Sjodahl
We construct a set of Wigner 6j symbols with gluon lines (adjoint representations) in closed form, expressed in terms of similar 6j symbols with quark lines (fundamental representa…
Spinning Pairs: Supporting Quark-Pair Creation from Landau Gauge Green's Functions
Reinhard Alkofer, Felipe J. Llanes-Estrada, Alexandre Salas-Bernardez
Abundant phenomenology suggests that strong decays from relatively low-excitation hadrons into other hadrons proceed by the creation of a light quark-antiquark pair with zero total…
Physics-informed Neural Network Estimation of Material Properties in Soft Tissue Nonlinear Biomechanical Models
Federica Caforio, Francesco Regazzoni, Stefano Pagani +5
The development of biophysical models for clinical applications is rapidly advancing in the research community, thanks to their predictive nature and their ability to assist the in…
Hilbert Direct Integrals of Monotone Operators
Minh N. Bùi, Patrick L. Combettes
Finite Cartesian products of operators play a central role in monotone operator theory and its applications. Extending such products to arbitrary families of operators acting on di…
Stellar spectral-type (mass) dependence of the dearth of close-in planets around fast-rotating stars. Architecture of Kepler confirmed single-exoplanet systems compared to star-planet evolution models
R. A. García, C. Gourvès, A. R. G. Santos +8
In 2013 a dearth of close-in planets around fast-rotating host stars was found using statistical tests on Kepler data. The addition of more Kepler and Transiting Exoplanet Survey S…
Modeling of Fluctuations in Dynamical Optoelectronic Device Simulations within a Maxwell-Density Matrix Langevin Approach
Johannes Popp, Johannes Stowasser, Michael A. Schreiber +5
We present a full-wave Maxwell-density matrix simulation tool including c-number stochastic noise terms for the modeling of the spatiotemporal dynamics in active photonic devices,…
Dynamical Chiral Symmetry Breaking in Quantum Chromo Dynamics: Delicate and Intricate
Reinhard Alkofer
Dynamical Chiral Symmetry Breaking (DCSB) in Quantum Chromo Dynamics (QCD) for the light quarks is an indispensable concept for understanding hadron physics, i.e., the spectrum and…
Pole-fitting for complex functions: enhancing standard techniques by artificial-neural-network classifiers and regressors
S. Kaidisch, T. U. Hilger, A. Krassnigg +1
Motivated by a use case in theoretical hadron physics, we revisit an application of a pole-sum fit to dressing functions of a confined quark propagator. More precisely, we investig…
Digital twinning of cardiac electrophysiology models from the surface ECG: a geodesic backpropagation approach
Thomas Grandits, Jan Verhülsdonk, Gundolf Haase +2
The eikonal equation has become an indispensable tool for modeling cardiac electrical activation accurately and efficiently. In principle, by matching clinically recorded and eikon…
The manifestly gauge-invariant spectrum of the Minimal Supersymmetric Standard Model
Axel Maas, Philipp Schreiner
Formal field theory requires, even in the presence of a Brout-Englert-Higgs effect, to maintain manifest non-perturbative gauge invariance. The Fröhlich-Morchio-Strocchi mechanism…
Photonic integrated processor for structured light detection and distinction
Johannes Bütow, Varun Sharma, Dorian Brandmüller +2
Integrated photonic devices have become pivotal elements across most research fields that involve light-based applications. A particularly versatile category of this technology are…
Heavy baryon spectroscopy in a quark-diquark approach
A. Torcato, A. Arriaga, G. Eichmann +1
We report progress on calculations of the heavy-light baryons and and their excitations with using functional methods. We employ a covariant quark-diquark…
The Fröhlich-Morchio-Strocchi mechanism: A underestimated legacy
Axel Maas
There is an odd tension in electroweak physics. Perturbation theory is extremely successful. At the same time, fundamental field theory gives manifold reasons why this should not b…
Generating free-space structured light with programmable integrated photonics
Johannes Bütow, Jörg S. Eismann, Varun Sharma +2
Structured light is a key component of many modern applications, ranging from superresolution microscopy to imaging, sensing, and quantum information processing. As the utilization…
Temperature and quantum anharmonic lattice effects on stability and superconductivity in lutetium trihydride
Roman Lucrezi, Pedro P. Ferreira, Markus Aichhorn +1
In this work, we resolve conflicting experimental and theoretical findings related to the dynamical stability and superconducting properties of -LuH, which was…
Search for ambient superconductivity in the Lu-N-H system
Pedro P. Ferreira, Lewis J. Conway, Alessio Cucciari +7
Motivated by the recent report of room-temperature superconductivity at near-ambient pressure in N-doped lutetium hydride by Dasenbrock et al. [Nature 615, 244 (2023)], we performe…
Multiorbital exciton formation in an organic semiconductor
Wiebke Bennecke, Andreas Windischbacher, David Schmitt +13
Harnessing the optoelectronic response of organic semiconductors requires a thorough understanding of the fundamental light-matter interaction that is dominated by the excitation o…
Photoemission orbital tomography for excitons in organic molecules
Christian S. Kern, Andreas Windischbacher, Peter Puschnig
Driven by recent developments in time-resolved photoemission spectroscopy, we extend the successful method of photoemission orbital tomography (POT) to excitons. Our theory retains…
