Web-based monitoring tool of the Atlantic Ocean observing system (Europe)

Web-based service tool that monitor data flow and key performance indicators of the Atlantic observing system. The focus here is on the monitoring of European contributions, including the EuroGOOS Atlantic ROOSES

A JOURNEY FROM THE OCTONIONIC ℙ2 TO A FAKE ℙ2

We discover a family of surfaces of general type with K2 = 3 and pg = q = 0 as free C13 quotients of special linear cuts of the octonionic projective plane Oℙ2. A special member of the family has 3 singularities of type A2, and is a quotient of a fake projective plane. We use the techniques of earlier work of Borisov and Fatighenti to define this fake projective plane by explicit equations in its bicanonical embedding

Dipolar-coupled entangled molecular 4f qubits

S.P. thanks the Novo Nordisk Foundation for research grant NNF20OC0065610. EPR Equipment funding by BBSRC to B. E. B. (17 Alert grant BB/R013780/1) is also gratefully acknowledged.We demonstrate by use of continuous wave- and pulse-electron paramagnetic resonance spectroscopy on oriented single crystals of magnetically dilute YbIII ions in Yb0.01Lu0.99(trensal) that molecular entangled two-qubit systems can be constructed by exploiting dipolar interactions between neighboring YbIII centers. Furthermore, we show that the phase memory time and Rabi frequencies of these dipolar-interaction-coupled entangled two-qubit systems are comparable to the ones of the corresponding single qubits.Publisher PDFPeer reviewe
