The isotropic attractor solution of axion-SU(2) inflation: Universal isotropization in Bianchi type-I geometry

Posted by klaurent Tokyo

Kavli Affiliate: Eiichiro Komatsu | First 5 Authors: Ira Wolfson, Azadeh Maleknejad, Tomoaki Murata, Eiichiro Komatsu, Tsutomu Kobayashi | Summary: SU(2) gauge fields coupled to an axion field can acquire an isotropic background solution during inflation. We study homogeneous but anisotropic inflationary solutions in the presence of such (massless) gauge fields. A gauge field in […]

AGN STORM 2: I. First results: A Change in the Weather of Mrk 817

Posted by klaurent MIT

Kavli Affiliate: Erin Kara | First 5 Authors: Erin Kara, Missagh Mehdipour, Gerard A. Kriss, Edward M. Cackett, Nahum Arav | Summary: We present the first results from the ongoing, intensive, multi-wavelength monitoring program of the luminous Seyfert 1 galaxy Mrk 817. While this AGN was, in part, selected for its historically unobscured nature, we […]

Adiabatic Construction of Hierarchical Quantum Hall States

Posted by klaurent MIT

Kavli Affiliate: Frank Wilczek | First 5 Authors: Martin Greiter, Frank Wilczek, , , | Summary: We propose an exact model of anyon ground states including higher Landau levels, and use it to obtain fractionally quantized Hall states at filling fractions $nu=p/(p(m-1)+1)$ with $m$ odd, from integer Hall states at $nu=p$ through adiabatic localization of […]

Design of a frequency-independent optic axis Pancharatnam-based achromatic half-wave plate

Posted by Tokyo

Kavli Affiliate: Tomotake Matsumura | First 5 Authors: Kunimoto Komatsu, Hirokazu Ishino, Nobuhiko Katayama, Tomotake Matsumura, Yuki Sakurai | Summary: Pancharatnam-based achromatic half-wave plates (AHWP) achieve high polarization efficiency over a broad waveband. These AWHPs generally contain a property whereby the optic axis is dependent on the electromagnetic frequency of the incident radiation. When the […]

Probing Strong Coupling between a Microwave Cavity and a Spin Ensemble with Raman Heterodyne Spectroscopy

Posted by Caltech

Kavli Affiliate: Andrei Faraon | First 5 Authors: Gavin G. G. King, Peter S. Barnett, John G. Bartholomew, Andrei Faraon, Jevon J. Longdell | Summary: Raman heterodyne spectroscopy is a powerful tool for characterizing the energy and dynamics of spins. The technique uses an optical pump to transfer coherence from a spin transition to an […]

Vibronic coupling in energy transfer dynamics and two-dimensional electronic-vibrational spectra

Posted by klaurent Berkeley

Kavli Affiliate: Graham R. Fleming | First 5 Authors: Eric A. Arsenault, Addison J. Schile, David T. Limmer, Graham R. Fleming, | Summary: We introduce a heterodimer model in which multiple mechanisms of vibronic coupling and their impact on energy transfer can be explicitly studied. We consider vibronic coupling that arises through either Franck-Condon activity […]
