Combining Frozen Trajectory Excitation and TACAW for in silico Time-Resolved Vibrational Electron Energy Loss/Gain Spectroscopy
Wojciech Marciniak, Joanna Marciniak, José Ãngel Castellanos-Reyes +1
Seeing that ultrafast (picosecond timescale) vibrational electron energy loss spectroscopy (EELS) should soon be experimentally realizable, we present in silico approach capable of…
A Changing-Look Seyfert Discovered by eROSITA Reveals a Two-Component Broad-Line Region
Alex Markowitz, Mirko Krumpe, David Homan +12
Extreme sudden changes in the flow of accreting gas onto SMBHs manifest themselves via large-amplitude continuum variability and changes to broad Balmer emission profiles, driving…
Universal Topological Power Transfer with Arbitrarily Large Chern Number in Driven Quantum Spin Chains
Anshuman Tripathi, Mircea Trif, Thore Posske
Topological frequency converters exploit a quantized transfer of power between two driving fields in a quantum system, a phenomenon topologically protected by the Chern number of t…
Isospin-symmetry violation -- kaons and beyond (ISO-BREAK 25: summary and outlook)
Marek Gazdzicki, Francesco Giacosa, Katarzyna Grebieszkow +40
This report summarizes the presentations and discussions during the ISO-BREAK 25 Workshop ``Isospin symmetry violation: kaons and beyond'', which was held at Jan Kochanowski Univer…
Quantum reservoir computing with classical and nonclassical states in an integrated optical circuit
S. Åwierczewski, W. Verstraelen, P. Deuar +3
Quantum reservoir computing (QRC) is a hardware-implementation-friendly quantum neural network scheme with minimal physical system requirements and a proven advantage over classica…
Weak emission line quasar SDSS J101353.45+492758.1 I. Continuum fitting
Laetitia Gibaud, Marek NikoÅajuk, Piotr Å»ycki +3
We present a broadband study of the WLQ SDSS J101353.45+492758.1, which displays a nearly featureless UV-optical spectrum with only a weak Mg II line alongside an exceptionally low…
