Site-selective enhancement of Eu emission in delta-doped GaN
Amelia R. Klein, Hayley J. Austin, Fumikazu Murakami +7
Europium-doped gallium nitride (GaN:Eu) is a promising platform for classical and quantum optoelectronic applications. When grown using organometallic vapor-phase epitaxy, the domi…
Nonlocal loss of first homotopy in polyhedral approximations of Peano continua
Jeremy Brazas, Hanspeter Fischer
If a Peano continuum is semilocally simply connected, then it has a finite polyhedral approximation whose fundamental group is isomorphic to that of . In general, this fails…
The Atacama Cosmology Telescope: DR6 Maps
Sigurd Naess, Yilun Guan, Adriaan J. Duivenvoorden +163
We present Atacama Cosmology Telescope (ACT) Data Release 6 (DR6) maps of the Cosmic Microwave Background temperature and polarization anisotropy at arcminute resolution over three…
The Atacama Cosmology Telescope: DR6 Constraints on Extended Cosmological Models
Erminia Calabrese, J. Colin Hill, Hidde T. Jense +169
We use new cosmic microwave background (CMB) primary temperature and polarization anisotropy measurements from the Atacama Cosmology Telescope (ACT) Data Release 6 (DR6) to test fo…
Optical modeling of systematic uncertainties in detector polarization angles for the Atacama Cosmology Telescope
Colin C. Murphy, Steve K. Choi, Rahul Datta +10
We present an estimate of the Atacama Cosmology Telescope (ACT) detector polarization angle systematic uncertainty from optics perturbation analysis using polarization-sensitive ra…
On R-trees, homotopies, and covering maps
Jeremy Brazas, Gregory R. Conner, Paul Fabel +1
A map has the \emph{unique path lifting} property if every path in , after a choice of an initial point, lifts uniquely to a path in . We prove that if a group …
