Nonlinear Flows for Displacement Correction and Applications in Tomography
Guozhi Dong, Otmar Scherzer
In this paper we derive nonlinear evolution equations associated with a class of non-convex energy functionals which can be used for correcting displacement errors in imaging data.…
Quasi-oscillatory dynamics observed in ascending phase of the flare on March 6, 2012
E. Philishvili, B. M. Shergelashvili, T. V. Zaqarashvili +5
Context. The dynamics of the flaring loops in active region (AR) 11429 are studied. The observed dynamics consist of several evolution stages of the flaring loop system during both…
Magnetospheric Multiscale Observations of Electron Vortex Magnetic Hole in the Magnetosheath Turbulent Plasma
S. Y. Huang, F. Sahraoui, Z. G. Yuan +29
We report the observations of an electron vortex magnetic hole corresponding to a new type of coherent structures in the magnetosheath turbulent plasma using the Magnetospheric Mul…
U(1) Wilson lattice gauge theories in digital quantum simulators
Christine Muschik, Markus Heyl, Esteban Martinez +7
Lattice gauge theories describe fundamental phenomena in nature, but calculating their real-time dynamics on classical computers is notoriously difficult. In a recent publication […
Efficient tomography of a quantum many-body system
B. P. Lanyon, C. Maier, M. Holzäpfel +10
Quantum state tomography (QST) is the gold standard technique for obtaining an estimate for the state of small quantum systems in the laboratory. Its application to systems with mo…
Direct observation of dynamical quantum phase transitions in an interacting many-body system
P. Jurcevic, H. Shen, P. Hauke +7
Dynamical quantum phase transitions (DQPTs) extend the concept of phase transitions and thus universality to the non-equilibrium regime. In this letter, we investigate DQPTs in a s…
Hunting for Stellar Coronal Mass Ejections
Heidi Korhonen, Krisztian Vida, Martin Leitzinger +2
Coronal mass ejections (CMEs) are explosive events that occur basically daily on the Sun. It is thought that these events play a crucial role in the angular momentum and mass loss…
A spectroscopic study of the open cluster NGC 6250
A. J. Martin, M. J. Stift, L. Fossati +4
We present the chemical abundance analysis of 19 upper main-sequence stars of the young open cluster NGC 6250 (log t ~ 7.42 yr). This work is part of a project aimed at setting obs…
Aeronomical constraints to the minimum mass and maximum radius of hot low-mass planets
L. Fossati, N. V. Erkaev, H. Lammer +7
Stimulated by the discovery of a number of close-in low-density planets, we generalise the Jeans escape parameter taking hydrodynamic and Roche lobe effects into account. We furthe…
Coherent Inflation for Large Quantum Superpositions of Microspheres
Oriol Romero-Isart
We show that coherent inflation, namely quantum dynamics generated by inverted conservative potentials acting on the center of mass of a massive object, is an enabling tool to prep…
Peculiar architectures for the WASP-53 and WASP-81 planet-hosting systems
Amaury H. M. J. Triaud, Marion Neveu-VanMalle, Monika Lendl +16
We report the detection of two new systems containing transiting planets. Both were identified by WASP as worthy transiting planet candidates. Radial-velocity observations quickly…
SALT observations of the Chromospheric Activity of Transiting Planet Hosts: Mass Loss and Star Planet Interactions
D. Staab, C. A. Haswell, Gareth D. Smith +4
We measured the chromospheric activity of the four hot Jupiter hosts WASP-43, WASP-51/HAT-P-30, WASP-72 & WASP-103 to search for anomalous values caused by the close-in companions.…
B field in OB stars (BOB): The outstandingly strong magnetic field in the evolved He-strong star CPD-62 2124
N. Castro, L. Fossati, S. Hubrig +12
The origin and evolution of magnetism in OB stars is far from being well understood. With approximately 70 magnetic OB stars known, any new object with unusual characteristics may…
Dark-Photon Search using Data from CRESST-II Phase 2
G. Angloher, P. Bauer, A. Bento +40
Identifying the nature and origin of dark matter is one of the major challenges for modern astro and particle physics. Direct dark-matter searches aim at an observation of dark-mat…
Derivation and analysis of continuum models for crossing pedestrian traffic
Sabine Hittmeir, Helene Ranetbauer, Christian Schmeiser +1
In this paper we study hyperbolic and parabolic nonlinear partial differential equation models, which describe the evolution of two intersecting pedestrian flows. We assume that in…
Observation of interspecies Feshbach resonances in an ultracold K-Cs mixture and refinement of interaction potentials
Michael Gröbner, Philipp Weinmann, Emil Kirilov +4
We observe interspecies Feshbach resonances due to s-wave bound states in ultracold K-Cs scattering for three different spin mixtures. The resonances are observed as…
Quantum theory from rules on information acquisition
Philipp A Hoehn
We summarise a recent reconstruction of the quantum theory of qubits from rules constraining an observer's acquisition of information about physical systems. This review of [arXiv:…
Laughlin-like states in bosonic and fermionic atomic synthetic ladders
Marcello Calvanese Strinati, Eyal Cornfeld, Davide Rossini +5
The combination of interactions and static gauge fields plays a pivotal role in our understanding of strongly-correlated quantum matter. Cold atomic gases endowed with a synthetic…
Quantum Performance of Thermal Machines over Many Cycles
Gentaro Watanabe, B. Prasanna Venkatesh, Peter Talkner +1
The performance of quantum heat engines is generally based on the analysis of a single cycle. We challenge this approach by showing that the total work performed by a quantum engin…
Searches for Lepton Number Violation and Resonances in Decays
2 collaboration
The NA48/2 experiment at CERN collected a large sample of charged kaon decays to final states with multiple charged particles in 2003--2004. A new upper limit on the rate of the le…
Degenerate Raman sideband cooling of 39K
Michael Gröbner, Philipp Weinmann, Emil Kirilov +1
We report on the first realization of sub-Doppler laser cooling of 39K atoms using degenerate 3D Raman sideband cooling. We take advantage of the well-resolved excited hyperfine st…
Distribution of high-dimensional entanglement via an intra-city free-space link
Fabian Steinlechner, Sebastian Ecker, Matthias Fink +5
Quantum entanglement is a fundamental resource in quantum information processing and its distribution between distant parties is a key challenge in quantum communications. Increasi…
