Computing The Packedness of Curves
Sepideh Aghamolaei, Vahideh Keikha, Mohammad Ghodsi +1
A polygonal curve with vertices is -packed, if the sum of the lengths of the parts of the edges of the curve that are inside any disk of radius is at most , for…
Conical spaces, modular invariance and holography
Joris Raeymaekers
We propose a non-unitary example of holography for the family of two-dimensional logarithmic conformal field theories with negative central charge $c= c_{p,1} = - 6p +13 - 6 p^{-1}…
Dynamically stabilized spin superfluidity in frustrated magnets
Ricardo Zarzuela, Daniel Hill, Jairo Sinova +1
We study the onset of spin superfluidity, namely coherent spin transport mediated by a topological spin texture, in frustrated exchange-dominated magnetic systems, engendered by an…
Antiferromagnetic fluctuations in the one-dimensional Hubbard model
Václav Janiš, Antonín Klíč, Jiawei Yan
We study the low-temperature critical behavior of the one-dimensional Hubbard model near half filling caused by enhanced antiferromagnetic fluctuations. We use a mean-field-type ap…
Light-time effect detected in fourteen eclipsing binaries
P. Zasche, R. Uhlar, P. Svoboda +2
The available minima timings of 14 selected eclipsing binaries (V1297 Cas, HD 24105, KU Aur, GU CMa, GH Mon, AZ Vel, DI Lyn, DK Her, GQ Dra, V624 Her, V1134 Her, KIC 6187893, V1928…
Fluorescence lifetime imaging via spatio-temporal speckle patterns in single-pixel camera configuration
Jiri Junek, Karel Zidek
Photoluminesce (PL) spectroscopy offers excellent methods for mapping the PL decay on the nanosecond time scale. However, capturing maps of emission dynamics on the microsecond tim…
