Generalized Lieb-Schultz-Mattis theorem on bosonic symmetry protected topological phases

Posted by klaurent July 19, 2019UCAS

Kavli Affiliate: Shenghan Jiang | First 5 Authors: Shenghan Jiang, Meng Cheng, Yang Qi, Yuan-Ming Lu, | Summary: We propose and prove a family of generalized Lieb-Schultz-Mattis (LSM) theorems for symmetry protected topological (SPT) phases on boson/spin models in any dimensions. The "conventional" LSM theorem, applicable to e.g. any translation invariant system with an odd […]

Entanglement, squeezing and state-swap in cholesteric liquid crystals

Posted by dbos July 18, 2019Delft

Kavli Affiliate: Ya M. Blanter | First 5 Authors: J. D. P. Machado, Ya. M. Blanter, , , | Summary: Phenomena such as state-swap, quadrature squeezing, entanglement and violation of entanglement inequalities are frequently reported to occur in quantum systems only. It is shown here that these effects can also occur in cholesteric liquid crystals […]

$Toverline{T}$ in AdS$_2$ and Quantum Mechanics

Posted by klaurent July 10, 2019UCSB

Kavli Affiliate: David J. Gross | First 5 Authors: David J. Gross, Jorrit Kruthoff, Andrew Rolph, Edgar Shaghoulian, | Summary: Quantum field theory in zero spatial dimensions has a rich infrared landscape and a universal ultraviolet, inverting the usual Wilsonian paradigm. For holographic theories this implies a rich landscape of asymptotically AdS$_2$ geometries. Isolating the […]

Shear measurement bias due to spatially varying spectral energy distributions in galaxies

Posted by klaurent July 9, 2019Stanford

Kavli Affiliate: Patricia R. Burchat | First 5 Authors: Sowmya Kamath, Joshua E. Meyers, Patricia R. Burchat, , | Summary: Galaxy color gradients – i.e., spectral energy distributions that vary across the galaxy profile – will impact galaxy shape measurements when the modeled point spread function (PSF) corresponds to that for a galaxy with spatially […]

Spontaneous Domain Formation in Spherically-Confined Elastic Filaments

Posted by dbos June 30, 2019UCAS

Kavli Affiliate: Rudolf Podgornik | First 5 Authors: Tine Curk, James Daniel Farrell, Jure Dobnikar, Rudolf Podgornik, | Summary: Although the free energy of a genome packing into a virus is dominated by DNA-DNA interactions, ordering of the DNA inside the capsid is elasticity-driven, suggesting general solutions with DNA organized into spool-like domains. Using analytical […]

Wide-angle spectrally selective absorbers and thermal emitters based on inverse opals

Posted by klaurent June 30, 2019Harvard

Kavli Affiliate: Anna V. Shneidman | First 5 Authors: Alireza Shahsafi, Graham Joe, Soeren Brandt, Anna V. Shneidman, Nicholas Stanisic | Summary: Engineered optical absorbers are of substantial interest for applications ranging from stray light reduction to energy conversion. We demonstrate a large-area (centimeter-scale) metamaterial that features near-unity frequency-selective absorption in the mid-infrared wavelength range. […]
