Stable charged cosmic strings
H. Weigel, M. Quandt, N. Graham
We study the quantum stabilization of a cosmic string by a heavy fermion doublet in a reduced version of the standard model. We show that charged strings, obtained by populating fe…
Casimir force between sharp-shaped conductors
Mohammad F. Maghrebi, Sahand Jamal Rahi, Thorsten Emig +3
Casimir forces between conductors at the sub-micron scale cannot be ignored in the design and operation of micro-electromechanical (MEM) devices. However, these forces depend non-t…
Cloning Voronoi Diagrams via Retroactive Data Structures
Matthew T. Dickerson, David Eppstein, Michael T. Goodrich
We address the problem of replicating a Voronoi diagram of a planar point set by making proximity queries, which are of three possible (in decreasing order of informatio…
Resolved shock structure of the Balmer-dominated filaments in Tycho's supernova remnant: Cosmic-ray precursor?
Jae-Joon Lee, John C. Raymond, Sangwook Park +4
We report on the results from Hα imaging observations of the eastern limb of Tycho's supernova remnant (SN1572) using the Wide Field Planetary Camera 2 on the Hubble Space Telescop…
Long-Lived Time-Dependent Remnants During Cosmological Symmetry Breaking: From Inflation to the Electroweak Scale
Marcelo Gleiser, Noah Graham, Nikitas Stamatopoulos
Through a detailed numerical investigation in three spatial dimensions, we demonstrate that long-lived time-dependent field configurations emerge dynamically during symmetry breaki…
