Are fractured cliffs the source of cometary dust jets ? Insights from OSIRIS/Rosetta at 67P
J. -B. Vincent, N. Oklay, M. Pajola +52
Dust jets, i.e. fuzzy collimated streams of cometary material arising from the nucleus, have been observed in-situ on all comets since the Giotto mission flew by comet 1P/Halley in…
On pluricanonical locally conformally Kähler manifolds
Andrei Moroianu, Sergiu Moroianu
We give a short proof of the fact that compact pluricanonical locally conformally Kähler manifolds have parallel Lee form.
Killing and Conformal Killing tensors
Konstantin Heil, Andrei Moroianu, Uwe Semmelmann
We introduce an appropriate formalism in order to study conformal Killing (symmetric) tensors on Riemannian manifolds. We reprove in a simple way some known results in the field an…
2-Xor revisited: satisfiability and probabilities of functions
Élie de Panafieu, Danièle Gardy, Bernhard Gittenberger +1
The problem 2-Xor-Sat asks for the probability that a random expression, built as a conjunction of clauses , is satisfiable. We revisit this classical problem by giving…
Hints on the origin of the thermal hysteresis suppression in giant magnetocaloric thin films irradiatied with highly charged ions
S Cervera, M Trassinelli, M Marangolo +13
In a recent experiment we demonstrated the possibility to suppress the thermal hysteresis of the phase transition in giant magnetocaloric MnAs thin film by interaction with slow hi…
Exciton dynamics and non-linearities in 2D-hybrid organic perovskites
K. Abdel-Baki, F. Boitier, H. Diab +6
Due to their high potentiality for photovoltaic applications or coherent light sources, a renewed interest in hybrid organic perovskites has emerged for few years. When they are ar…
