Minimal Zeeman field requirement for a topological transition in superconductors

Posted by klaurent November 16, 2020Delft

Kavli Affiliate: Michael Wimmer | First 5 Authors: Kim Pöyhönen, Daniel Varjas, Michael Wimmer, Anton R. Akhmerov, | Summary: Platforms for creating Majorana quasiparticles rely on superconductivity and breaking of time-reversal symmetry. By studying continuous deformations to known trivial states, we find that the relationship between superconducting pairing and time reversal breaking imposes rigorous bounds […]

From the Black Hole Conundrum to the Structure of Quantum Gravity

Posted by klaurent November 16, 2020Tokyo

Kavli Affiliate: Yasunori Nomura | First 5 Authors: Yasunori Nomura, , , , | Summary: We portray the structure of quantum gravity emerging from recent progress in understanding the quantum mechanics of an evaporating black hole. Quantum gravity admits two different descriptions, based on Euclidean gravitational path integral and a unitarily evolving holographic quantum system, […]

Alzheimer’s-associated upregulation of mitochondria-associated ER membranes after traumatic brain injury

Posted by klaurent November 15, 2020November 14, 2022Columbia

Kavli Affiliate: Daphna Shohamy | Authors: Jonathan Nicholas, Christian Amlang, Chi-Ying Lin, Leila Montaser-Kouhsari, Natasha Desai, Ming-Kai Pan, Sheng-Han Kuo and Daphna Shohamy | Summary: Abstract Traumatic brain injury (TBI) can lead to neurodegenerative diseases such as Alzheimer’s disease (AD) through mechanisms that remain incompletely characterized. Similar to AD, TBI models present with cellular metabolic […]

A roadmap to strange star

Posted by klaurent November 14, 2020Peking

Kavli Affiliate: Renxin Xu | First 5 Authors: Renxin Xu, Xiaoyu Lai, Chengjun Xia, , | Summary: What if normal baryonic matter is compressed so tightly that atomic nuclei come into close contact? This question has been asked since 1930s. The fist answer was presented by Lev Landau whose speculation has been developed, and the […]

Correlated X-ray and optical variability in the O-type supergiant zeta Puppis

Posted by klaurent November 13, 2020MIT

Kavli Affiliate: David P. Huenemoerder | First 5 Authors: Joy S. Nichols, Yael Naze, David P. Huenemoerder, Anthony F. J. Moffat, Nathan Miller | Summary: Analysis of the recent long exposure Chandra X-ray observation of the early-type O star zeta Pup shows clear variability with a period previously reported in optical photometric studies. These 813 […]

Virtual Distillation for Quantum Error Mitigation

Posted by November 13, 2020Berkeley

Kavli Affiliate: K. Birgitta Whaley | First 5 Authors: William J. Huggins, Sam McArdle, Thomas E. O’Brien, Joonho Lee, Nicholas C. Rubin | Summary: Contemporary quantum computers have relatively high levels of noise, making it difficult to use them to perform useful calculations, even with a large number of qubits. Quantum error correction is expected […]

On Rational Points in CFT Moduli Spaces

Posted by klaurent November 13, 2020Tokyo

Kavli Affiliate: Hirosi Ooguri | First 5 Authors: Nathan Benjamin, Christoph A. Keller, Hirosi Ooguri, Ida G. Zadeh, | Summary: Motivated by the search for rational points in moduli spaces of two-dimensional conformal field theories, we investigate how points with enhanced symmetry algebras are distributed there. We first study the bosonic sigma-model with $S^1$ target […]

COOL-LAMPS I. An Extraordinarily Bright Lensed Galaxy at Redshift 5.04

Posted by November 12, 2020Chicago

Kavli Affiliate: Michael D. Gladders | First 5 Authors: Gourav Khullar, Katya Gozman, Jason J. Lin, Michael N. Martinez, Owen S. Matthews Acuña | Summary: We report the discovery of COOL J1241+2219, a strongly-lensed galaxy at redshift $z$=5.043$pm$0.002 with observed magnitude $z_{AB}=20.47$, lensed by a moderate-mass galaxy cluster at $z$=1.001$pm$0.001. COOL J1241+2219 is the brightest […]
