Capture and sorting of multiple cells by polarization-controlled three-beam interference [PDF]
, 2016 For the capture and sorting of multiple cells, a sensitive and highly efficient polarization-controlled three-beam interference set-up has been developed. With the theory of superposition of three beams, simulations on the influence of polarization angle

Polarization of Thermal X-rays from Isolated Neutron Stars [PDF]
, 1999 Since the opacity of a magnetized plasma depends on polarization of radiation, the radiation emergent from atmospheres of neutron stars with strong magnetic fields is expected to be strongly polarized. The degree of linear polarization, typically ~10-30%,

Canadian Journal of Mathematics, 2003 AbstractFor complex projective manifolds we introduce polar homology groups, which are holomorphic analogues of the homology groups in topology. The polar k-chains are subvarieties of complex dimension k with meromorphic forms on them, while the boundary operator is defined by taking the polar divisor and the Poincaré residue on it. One can also define

Broadband and tunable terahertz absorption based on ethanol-treated carbon nanotube sponges
Results in Physics, 2022 To eliminate the undesired terahertz (THz) interference and echo, broadband and tunable THz absorbing devices are urgently needed. Herein, we report a simple method to obtain an active THz absorption performance by ethanol-treated carbon nanotube sponges

The dynamics of political polarization
Proceedings of the National Academy of Sciences of the United States of America, 2021 A number of trends in national and international politics greatly affect our capacity to achieve the cooperation that will be necessary to address the challenges facing society over the coming decades.

Mueller Matrix Imaging Optimized by Uniform Illumination
Frontiers in Physics, 2022 In this study, we present a flat-field Mueller matrix imaging system to reduce the reconstruction error caused by critical illumination. This study demonstrates that the signal-to-noise ratio (SNR) of the reconstructed images is improved by about eight ...

Broadband spectral shaping using nematic liquid crystal
Results in Physics, 2019 We demonstrate what is, to our knowledge, the first implementation of nematic liquid crystal (LC) for spectral shaping of broadband light fields. A LC cell of several microns thickness is placed between a polarizer and an analyzer.

Polarization Swings Reveal Magnetic Energy Dissipation in Blazars [PDF]
, 2015 The polarization signatures of the blazar emissions are known to be highly variable. In addition to small fluctuations of the polarization angle around a mean value, sometimes large (> 180^o) polarization angle swings are observed. We suggest that such p
