Quantum frequency doubling in the topological insulator Bi2Se3
Pan He, Hiroki Isobe, Dapeng Zhu +3
The nonlinear Hall effect due to Berry curvature dipole (BCD) induces frequency doubling, which was recently observed in time-reversal-invariant materials. Here we report novel ele…
Stoichiometric Bi2Se3 Topological Insulator Ultra-Thin Films Obtained Through a New Fabrication Process for Optoelectronic Applications
Matteo Salvato, Mattia Scagliotti, Maurizio De Crescenzi +7
A new fabrication process is developed for growing Bi2Se3 topological insulators in the form of nanowires/nanobelts and ultra-thin films. It consists of two consecutive procedures:…
Optimal CMB Lensing Reconstruction and Parameter Estimation with SPTpol Data
M. Millea, C. M. Daley, T-L. Chou +66
We perform the first simultaneous Bayesian parameter inference and optimal reconstruction of the gravitational lensing of the cosmic microwave background (CMB), using 100 deg o…
The Atacama Cosmology Telescope: Weighing distant clusters with the most ancient light
Mathew S. Madhavacheril, Cristóbal Sifón, Nicholas Battaglia +58
We use gravitational lensing of the cosmic microwave background (CMB) to measure the mass of the most distant blindly-selected sample of galaxy clusters on which a lensing measurem…
A Demonstration of Improved Constraints on Primordial Gravitational Waves with Delensing
BICEP/Keck, SPTpol Collaborations, : +139
We present a constraint on the tensor-to-scalar ratio, , derived from measurements of cosmic microwave background (CMB) polarization -modes with "delensing," whereby the unce…
Searching for Anisotropic Cosmic Birefringence with Polarization Data from SPTpol
F. Bianchini, W. L. K. Wu, P. A. R. Ade +69
We present a search for anisotropic cosmic birefringence in 500 deg of southern sky observed at 150 GHz with the SPTpol camera on the South Pole Telescope. We reconstruct a map…
