A little FABLE: exploring AGN feedback in dwarf galaxies with cosmological simulations

Kavli Affiliate: Debora Sijacki | First 5 Authors: Sophie Koudmani, Nicholas A. Henden, Debora Sijacki, , | Summary: Contrary to the standard lore, there is mounting observational evidence that feedback from active galactic nuclei (AGN) may also play a role at the low-mass end of the galaxy population. We investigate this using the cosmological simulation […]

Kazhdan-Lusztig conjecture via Zastava spaces

Kavli Affiliate: Hiraku Nakajima | First 5 Authors: Alexander Braverman, Michael Finkelberg, Hiraku Nakajima, , | Summary: We deduce the Kazhdan-Lusztig conjecture on the multiplicities of simple modules over a simple complex Lie algebra in Verma modules in category O from the equivariant geometric Satake correspondence and the analysis of torus fixed points in zastava […]

Band gap renormalization, carrier mobilities, and the electron-phonon self-energy in crystalline naphthalene

Kavli Affiliate: Jeffrey B. Neaton | First 5 Authors: Florian Brown-Altvater, Gabriel Antonius, Tonatiuh Rangel, Matteo Giantomassi, Claudia Draxl | Summary: Organic molecular crystals are expected to feature appreciable electron-phonon interactions that influence their electronic properties at zero and finite temperature. In this work, we report first-principles calculations and an analysis of the electron-phonon self-energy […]

Ultrafast dynamics of electron-phonon coupling in a metal

Kavli Affiliate: Alessandra Lanzara | First 5 Authors: Choongyu Hwang, Wentao Zhang, Koshi Kurashima, Robert Kaindl, Tadashi Adachi | Summary: In the past decade, the advent of time-resolved spectroscopic tools has provided a new ground to explore fundamental interactions in solids and to disentangle degrees of freedom whose coupling leads to broad structures in the […]

Inductive construction of stable envelopes

Kavli Affiliate: Andrei Okounkov | First 5 Authors: Andrei Okounkov, , , , | Summary: We revisit the construction of stable envelopes in equivariant elliptic cohomology [arXiv:1604.00423] and give a direct inductive proof of their existence and uniqueness in a rather general situation. We also discuss the specialization of this construction to equivariant K-theory. | […]

The Cepheid Distance to the Seyfert 1 Galaxy NGC 4151

Kavli Affiliate: Michael M. Fausnaugh | First 5 Authors: Wenlong Yuan, Michael M. Fausnaugh, Samantha L. Hoffmann, Lucas M. Macri, Bradley M. Peterson | Summary: We derive a distance of $15.8pm0.4$ Mpc to the archetypical Seyfert 1 galaxy NGC 4151 based on the near-infrared Cepheid Period-Luminosity relation and new Hubble Space Telescope multiband imaging. This […]

Nanoscale axial position and orientation measurement of hexagonal boron nitride quantum emitters using a tunable nanophotonic environment

Kavli Affiliate: Harry A. Atwater | First 5 Authors: Pankaj K. Jha, Hamidreza Akbari, Yonghwi Kim, Souvik Biswas, Harry A. Atwater | Summary: Color centers in hexagonal boron nitride (hBN) have emerged as promising candidates for single-photon emitters (SPEs) due to their bright emission characteristics at room temperature. In contrast to mono- and few-layered hBN, […]

Bitcoin Trace-Net: Formal Contract Verification at Signing Time

Kavli Affiliate: James Chiang | First 5 Authors: James Chiang, , , , | Summary: Smart contracting protocols promise to regulate the transfer of cryptocurrency amongst participants in a trustless manner. A safe smart contract implementation should ensure that each participant can always append a contract transaction to the blockchain in order move the contract […]

Kirigami-inspired inflatables with programmable shapes

Kavli Affiliate: Katia Bertoldi | First 5 Authors: Lishuai Jin, Antonio Elia Forte, Bolei Deng, Ahmad Rafsanjani, Katia Bertoldi | Summary: Kirigami, the Japanese art of paper cutting, has recently enabled the design of stretchable mechanical metamaterials that can be easily realized by embedding arrays of periodic cuts into an elastic sheet. Here, we exploit […]
