Competing correlated states around the zero field Wigner crystallization transition of electrons in two-dimensions

Posted by March 30, 2021Caltech

Kavli Affiliate: Joseph Falson | First 5 Authors: Joseph Falson, Inti Sodemann, Brian Skinner, Daniela Tabrea, Yusuke Kozuka | Summary: The competition between kinetic energy and Coulomb interactions in electronic systems can lead to complex many-body ground states with competing superconducting, charge density wave, and magnetic orders. Here we study the low temperature phases of […]

Gaia EDR3 Parallax Zero-point Offset based on W Ursae Majoris-type Eclipsing Binaries

Posted by klaurent March 30, 2021Peking

Kavli Affiliate: Huawei Zhang | First 5 Authors: Fangzhou Ren, Xiaodian Chen, Huawei Zhang, Richard de Grijs, Licai Deng | Summary: We independently determine the zero-point offset of the Gaia early Data Release-3 (EDR3) parallaxes based on $sim 110,000$ W Ursae Majoris (EW)-type eclipsing binary systems. EWs cover almost the entire sky and are characterized […]

Narain to Narnia

Posted by klaurent March 29, 2021Tokyo

Kavli Affiliate: Hirosi Ooguri | First 5 Authors: Nathan Benjamin, Christoph A. Keller, Hirosi Ooguri, Ida G. Zadeh, | Summary: We generalize the holographic correspondence between topological gravity coupled to an abelian Chern-Simons theory in three dimensions and an ensemble average of Narain’s family of massless free bosons in two dimensions, discovered by Afkhami-Jeddi et […]

Chaotic scattering of highly excited strings

Posted by dbos March 29, 2021UCSB

Kavli Affiliate: David J. Gross | First 5 Authors: David J. Gross, Vladimir Rosenhaus, , , | Summary: Motivated by the desire to understand chaos in the $S$-matrix of string theory, we study tree level scattering amplitudes involving highly excited strings. While the amplitudes for scattering of light strings have been a hallmark of string […]

Inference of the optical depth to reionization from low multipole temperature and polarisation Planck data

Posted by klaurent March 26, 2021Cambridge

Kavli Affiliate: George Efstathiou | First 5 Authors: Roger de Belsunce, Steven Gratton, William Coulton, George Efstathiou, | Summary: This paper explores methods for constructing low multipole temperature and polarisation likelihoods from maps of the cosmic microwave background anisotropies that have complex noise properties and partial sky coverage. We use Planck 2018 High Frequency Instrument […]

QuasarNet: A new research platform for the data-driven investigation of black holes

Posted by March 25, 2021Chicago

Kavli Affiliate: Brian Nord | First 5 Authors: Priyamvada Natarajan, Kwok Sun Tang, Robert McGibbon, Sadegh Khochfar, Brian Nord | Summary: We present QuasarNet, a novel research platform for the data-driven investigation of super-massive black hole (SMBH) populations. While SMBH data sets — observations and simulations — have grown rapidly in complexity and abundance, our […]

Conformal gravity does not predict flat galaxy rotation curves

Posted by klaurent March 24, 2021Cambridge

Kavli Affiliate: Anthony Lasenby | First 5 Authors: Michael Hobson, Anthony Lasenby, , , | Summary: We reconsider the widely held view that the Mannheim–Kazanas (MK) vacuum solution for a static, spherically-symmetric system in conformal gravity (CG) predicts flat rotation curves, such as those observed in galaxies, without the need for dark matter. This prediction […]

Spatial Decorrelation of Young Stars and Dense Gas as a Probe of the Star Formation-Feedback Cycle in Galaxies

Posted by March 24, 2021Chicago

Kavli Affiliate: Andrey V. Kravtsov | First 5 Authors: Vadim A. Semenov, Andrey V. Kravtsov, Nickolay Y. Gnedin, , | Summary: The spatial decorrelation of dense molecular gas and young stars observed on $lesssim 1$ kiloparsec scales in nearby galaxies indicates rapid dispersal of star-forming regions by stellar feedback. We explore the sensitivity of this […]
