The slow motion of #Uranus in just one day (24 hours ago and tonight), easily visible thanks to the current proximity to the stars 14 and 13 Tauri of similar brightness: facebook.com/planetarium.bochu - one could also see the changing shape of the triangle in binoculars!

Quantum thermodynamics of Gross-Pitaevskii qubits
What are the resources that can be leveraged for a thermodynamic device to exhibit genuine quantum advantage? Typically, the answer to this question is sought in quantum correlations. In the present work, we show that quantum Otto engines that operate with nonlinear qubits significantly outperform linear engines. To this end, we develop a comprehensive thermodynamic description of nonlinear qubits starting with identifying the proper thermodynamic equilibrium state. We then show that for ideal …

Influence of Platinum Thin Films on the Photophysical and Quantum Properties of Near-Surface NV Centers
Nitrogen-vacancy (NV) centers in diamond are optically addressable spin defects with great potential for nanoscale quantum sensing. A key application of NV centers is the detection of external spins at the diamond surface. Among metals, platinum thin films - widely used in spintronics, catalysis and electrochemistry - provide a particularly interesting system for such studies. However, the interaction between NV centers and metals is known to affect their quantum sensing capabilities. In this w…

@… O, to to - z tym się zgadzam. Dlatego regulacje w stylu GDPR są długofalowe i uniwersalne, na podstawie których można regularnie karać. Gdyby podobna inicjatywa powstała dla działania social mediów, czy ogólnie mediów, jak ta dla ochrony danych - podpisał bym się pod tym.

MSHT Approximate N3LO PDFs: Updates and Consequences for Phenomenology

MSHT Approximate N3LO PDFs: Updates and Consequences for Phenomenology
We present updates to the MSHT approximate N3LO PDFs focusing upon recent developments, examining the impacts of newly determined splitting function and transition matrix element calculations, performed since the public MSHT20aN3LO PDF set was released. We observe only small changes to the output PDFs, at most of similar size to their quoted uncertainties and typically notably less. Finally, we also present the impacts on the PDF luminosities, where changes are generally further reduced.

🏒 Photographing Professional Hockey with the Sigma 135mm f/1.4 Art
... I'm a believer because I shoot indoor sports with the Sony 135mm f/1.8

Photographing Professional Hockey with the Sigma 135mm f/1.4 Art
Sometimes it is the least obvious choice that produces the most striking results. That is why I ended up photographing a hockey game in the Swiss National
