Twist of generalized skyrmions and spin vortices in a polariton superfluid
Stefano Donati, Lorenzo Dominici, Galbadrakh Dagvadorj +7
We study the spin vortices and skyrmions coherently imprinted into an exciton-polariton condensate on a planar semiconductor microcavity. We demonstrate that the presence of a pola…
Active shape-morphing elastomeric colloids in short-pitch cholesteric liquid crystals
Julian S. Evans, Yaoran Sun, Bohdan Senyuk +4
Active elastomeric liquid crystal particles with initial cylindrical shapes are obtained by means of soft lithography and polymerization in a strong magnetic field. Gold nanocrysta…
Geodesics dynamics in the Linet-Tian spacetime with Lambda>0
Irene Brito, M. F. A. Da Silva, Filipe C. Mena +1
We analyse the geodesics' dynamics in cylindrically symmetric vacuum spacetimes with Lambda>0 and compare it to the Lambda=0 and Lambda<0 cases. When Lambda>0 there are two singula…
Period spacings in red giants; III. Coupling factors of mixed modes
B. Mosser, C. Pinçon, K. Belkacem +2
The power of asteroseismology relies on the capability of global oscillations to infer the stellar structure. For evolved stars, we benefit from unique information directly carried…
Testing Predictions of the Quantum Landscape Multiverse 2: The Exponential Inflationary Potential
Eleonora Di Valentino, Laura Mersini-Houghton
The 2015 Planck data release tightened the region of the allowed inflationary models. Inflationary models with convex potentials have now been ruled out since they produce a large…
A model for stealth coronal mass ejections
B. J. Lynch, S. Masson, Y. Li +4
Stealth coronal mass ejections (CMEs) are events in which there are almost no observable signatures of the CME eruption in the low corona but often a well-resolved slow flux rope C…
