On clean, weakly clean, and feebly clean commutative group rings
Yuanlin Li, Qinghai Zhong
A ring is said to be clean if each element of can be written as the sum of a unit and an idempotent. is said to be weakly clean if each element of is either a sum o…
Kelvin's Chirality of Optical Beams
Sergey Nechayev, Jörg S. Eismann, Rasoul Alaee +3
Geometrical chirality is a property of objects that describes three-dimensional mirror-symmetry violation and therefore it requires a non-vanishing spatial extent. In contrary, opt…
Topological transitions to Weyl states in bulk BiSe: Effect of hydrostatic pressure and doping
Sudip Kumar Saha, Hrishit Banerjee, Manoranjan Kumar
BiSe, a layered three dimensional (3D) material, exhibits topological insulating properties due to presence of surface states and a band gap of 0.3 eV in the bulk. We study…
Electronic, vibrational, and electron-phonon coupling properties in SnSe and SnS under pressure
Gyanu Prasad Kafle, Christoph Heil, Hari Paudyal +1
The tin-selenide and tin-sulfide classes of materials undergo multiple structural transitions under high pressure leading to periodic lattice distortions, superconductivity, and to…
Tracing orbital images on ultrafast time scales
Robert Wallauer, Miriam Raths, Klaus Stallberg +10
Frontier orbitals, i.e., the highest occupied and lowest unoccupied orbitals of a molecule, generally determine molecular properties, such as chemical bonding and reactivities. Con…
Gauge-invariant description of the Higgs resonance and its phenomenological implications
Axel Maas, René Sondenheimer
We investigate the phenomenological consequences of a strict gauge-invariant formulation of the Higgs particle. This requires a description of the observable scalar particle in ter…
Half-metallic ferromagnetism in layered CdOHCl induced by hole doping
Hrishit Banerjee, Paolo Barone, Silvia Picozzi
Next-generation spintronic devices will benefit from low-dimensionality, ferromagnetism, and half-metallicity, possibly controlled by electric fields. We find these technologically…
Molecular anchoring stabilizes low valence Ni(I)TPP on copper against thermally induced chemical changes
Henning Maximilian Sturmeit, Iulia Cojocariu, Matteo Jugovac +14
Many applications of molecular layers deposited on metal surfaces, ranging from single-atom catalysis to on-surface magnetochemistry and biosensing, rely on the use of thermal cycl…
Weighing stars from birth to death: mass determination methods across the HRD
Aldo Serenelli, Achim Weiss, Conny Aerts +31
The mass of a star is the most fundamental parameter for its structure, evolution, and final fate. It is particularly important for any kind of stellar archaeology and characteriza…
Lattices over Bass rings and graph agglomerations
Nicholas R. Baeth, Daniel Smertnig
We study direct-sum decompositions of torsion-free, finitely generated modules over a (commutative) Bass ring through the factorization theory of the corresponding monoid $T(R)…
Quantum Confinement Induced Metal-Insulator Transition in Strongly Correlated Quantum Wells of SrVO Superlattice
A. D. N. James, M. Aichhorn, J. Laverock
Dynamical mean-field theory (DMFT) has been employed in conjunction with density functional theory (DFT+DMFT) to investigate the metal-insulator transition (MIT) of strongly correl…
Signatures of an Atomic Crystal in the Band Structure of a Molecular Thin Film
Norman Haag, Daniel Lüftner, Johannes Seidel +8
Transport phenomena in molecular materials are intrinsically linked to the orbital character and the degree of localization of the valence states. Here, we combine angle-resolved p…
High-Temperature Conventional Superconductivity in the Boron-Carbon system: Material Trends
Santanu Saha, Simone Di Cataldo, Maximilian Amsler +23
In this work we probe the possibility of high-temperature conventional superconductivity in the boron-carbon system, using ab-initio screening. A database of 320 metastable structu…
Transverse spinning of unpolarized light
J. S. Eismann, L. H. Nicholls, D. J. Roth +6
It is well known that spin angular momentum of light, and therefore that of photons, is directly related to their circular polarization. Naturally, for totally unpolarized light, p…
Spectrum of scalar and pseudoscalar glueballs from functional methods
Markus Q. Huber, Christian S. Fischer, Hèlios Sanchis-Alepuz
We provide results for the spectrum of scalar and pseudoscalar glueballs in pure Yang-Mills theory using a parameter-free fully self-contained truncation of Dyson-Schwinger and Bet…
Emergence of a ferromagnetic insulating state in LaMnO/SrTiO heterostructures: The role of strong electronic correlations and strain
Hrishit Banerjee, Markus Aichhorn
Inspired by the experimental findings of an exotic ferromagnetic insulating state in LaMnO/SrTiO heterostructures, we calculate the electronic and magnetic state of LaMnO$_…
A composite massless vector boson
Vincenzo Afferrante, Axel Maas, Pascal Törek
In a non-perturbative gauge-invariant formulation of grand-unified theories all low energy vector states need to be composite with respect to the high-scale gauge group, including…
Evaluating Computational Shortcuts in Supercell-Based Phonon Calculations of Molecular Crystals: The Instructive Case of Naphthalene
Tomas Kamencek, Sandro Wieser, Hirotaka Kojima +4
Phonons crucially impact a variety of properties of organic semiconductor materials. For instance, charge- and heat transport depend on low-frequency phonons, while for other prope…
Constraining the Higgs valence contribution in the proton
Simon Fernbach, Lukas Lechner, Axel Maas +2
Non-perturbative gauge-invariance under the strong and the weak interactions dictates that the proton contains a non-vanishing valence contribution from the Higgs particle. By intr…
Time evolution of entanglement negativity across a defect
Matthias Gruber, Viktor Eisler
We consider a quench in a free-fermion chain by joining two homogeneous half-chains via a defect. The time evolution of the entanglement negativity is studied between adjacent segm…
