Hard X-ray emission lines from the decay of Ti-44 in the remnant of supernova 1987A

S. A. Grebenev, A. A. Lutovinov, S. S. Tsygankov +1

It is assumed that the radioactive decay of Ti-44 powers the infrared, optical and UV emission of supernova remnants after the complete decay of Co-56 and Co-57 (the isotopes that…

The Snake Instability of Ring Dark Solitons in Toroidally Trapped Bose-Einstein Condensates

Lauri Toikka, Kalle-Antti Suominen

We show that the onset of the snake instability of ring dark solitons requires a broken symmetry. We also elucidate explicitly the connection between imaginary Bogoliubov modes and…

Baryon asymmetry and dark matter from soft leptogenesis

Heidi Kuismanen, Iiro Vilja

The framework for soft leptogenesis minimally extended with a DM sector is studied. A heavy singlet neutrino superfield acts as the source for (s)lepton asymmetry and by coupling t…

Optimal state pairs for non-Markovian quantum dynamics

Steffen Wissmann, Antti Karlsson, Elsi-Mari Laine +2

We study a recently proposed measure for the quantification of quantum non-Markovianity in the dynamics of open systems which is based on the exchange of information between the op…

2D atom localization in a four-level tripod system in laser fields

Vladimir Ivanov, Yuri Rozhdestvensky

We propose a scheme for two-dimensional (2D) atom localization in a four-level tripod system under an influence of two orthogonal standing-wave fields. Position information of the…

Quasiconformal maps with bilipschitz or identity boundary values in Banach spaces

Y. Li, M. Vuorinen, X. Wang

Suppose that and denote real Banach spaces with dimension at least 2 and that and are uniform domains with homogeneously dense boun…
