Dust in a compact, cold, high-velocity cloud: A new approach to removing foreground emission

Daniel Lenz, Lars Flöer, Jürgen Kerp

Because isolated high-velocity clouds (HVCs) are found at great distances from the Galactic radiation field and because they have subsolar metallicities, there have been no detecti…

Energy Bounds for a Compressed Elastic Film on a Substrate

David P. Bourne, Sergio Conti, Stefan Müller

We study pattern formation in a compressed elastic film which delaminates from a substrate. Our key tool is the determination of rigorous upper and lower bounds on the minimum valu…

Spontaneous symmetry breaking and phase coherence of a photon Bose-Einstein condensate coupled to a reservoir

Julian Schmitt, Tobias Damm, David Dung +4

We examine the phase evolution of a Bose-Einstein condensate of photons generated in a dye microcavity by temporal interference with a phase reference. The photo-excitable dye mole…

Symmetry breaking in indented elastic cones

Sergio Conti, Heiner Olbermann, Ian Tobasco

Motivated by simulations of carbon nanocones (see Jordan and Crespi, Phys. Rev. Lett., 2004), we consider a variational plate model for an elastic cone under compression in the dir…

Deformation concentration for martensitic microstructures in the limit of low volume fraction

Sergio Conti, Johannes Diermeier, Barbara Zwicknagl

We consider a singularly-perturbed nonconvex energy functional which arises in the study of microstructures in shape memory alloys. The scaling law for the minimal energy predicts…

Detecting stellar-wind bubbles through infrared arcs in HII regions

Jonathan Mackey, Thomas J. Haworth, Vasilii V. Gvaramadze +3

Mid-infrared arcs of dust emission are often seen near ionizing stars within HII regions. A possible explanations for these arcs is that they could show the outer edges of asymmetr…

Searches for Relativistic Magnetic Monopoles in IceCube

IceCube Collaboration, M. G. Aartsen, K. Abraham +306

Various extensions of the Standard Model motivate the existence of stable magnetic monopoles that could have been created during an early high-energy epoch of the Universe. These p…

Folding patterns in partially delaminated thin films

David Bourne, Sergio Conti, Stefan Müller

Michael Ortiz and Gustavo Gioia showed in the 90s that the complex patterns arising in compressed elastic films can be analyzed within the context of the calculus of variations. Th…

Abstract tilting theory for quivers and related categories

Moritz Groth, Jan Stovicek

We generalize the construction of reflection functors from classical representation theory of quivers to arbitrary small categories with freely attached sinks or sources. These ref…
