Sketching with Kerdock’s crayons: Fast sparsifying transforms for arbitrary linear maps

Kavli Affiliate: David Gross | First 5 Authors: Tim Fuchs, David Gross, Felix Krahmer, Richard Kueng, Dustin G. Mixon | Summary: Given an arbitrary matrix $Ainmathbb{R}^{ntimes n}$, we consider the fundamental problem of computing $Ax$ for any $xinmathbb{R}^n$ such that $Ax$ is $s$-sparse. While fast algorithms exist for particular choices of $A$, such as the […]

Thermal anyon interferometry in phonon-coupled Kitaev spin liquids

Kavli Affiliate: Joel E. Moore | First 5 Authors: Kai Klocke, Joel E. Moore, Jason Alicea, Gábor B. Halász, | Summary: Recent theoretical studies inspired by experiments on the Kitaev magnet $alpha$-RuCl$_3$ highlight the nontrivial impact of phonons on the thermal Hall conductivity of chiral topological phases. Here we introduce mixed mesoscopic-macroscopic devices that allow […]

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

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

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

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

Kavli Affiliate: Nobuhiko Katayama | First 5 Authors: [#item_custom_name[1]], [#item_custom_name[2]], [#item_custom_name[3]], [#item_custom_name[4]], [#item_custom_name[5]] | 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 AHWP is used to measure […]
