Modular Parametrization as Polyakov Path Integral: Cases with CM Elliptic Curves as Target Spaces

Kavli Affiliate: Taizan Watari | First 5 Authors: Satoshi Kondo, Taizan Watari, , , | Summary: For an elliptic curve E over an abelian extension k/K with CM by K of Shimura type, the L-functions of its [k:K] Galois representations are Mellin transforms of Hecke theta functions; a modular parametrization (surjective map) from a modular […]

Black Hole Memory

Kavli Affiliate: Robert M. Wald | First 5 Authors: Adel A. Rahman, Robert M. Wald, , , | Summary: The memory effect at null infinity, $mathcal{I}^+$, can be defined in terms of the permanent relative displacement of test particles (at leading order in $1/r$) resulting from the passage of a burst of gravitational radiation. In […]

Effect of surface chemistry on incorporation of nanoparticles within calcite single crystals

Kavli Affiliate: Joanna Aizenberg | First 5 Authors: Giulia Magnabosco, Iryna Polishchuk, Francesco Palomba, Enrico Rampazzo, Luca Prodi | Summary: Inclusion of additives into calcite crystals allows one to embed non-native proprieties into the inorganic matrix and obtain new functional materials. Up to now, few parameters have been taken into account to evaluate the efficiency […]

A Non-Abelian Analogue of DBI from $T overline{T}$

Kavli Affiliate: Savdeep Sethi | First 5 Authors: T. Daniel Brennan, Christian Ferko, Savdeep Sethi, , | Summary: The Dirac action describes the physics of the Nambu-Goldstone scalars found on branes. The Born-Infeld action defines a non-linear theory of electrodynamics. The combined Dirac-Born-Infeld (DBI) action describes the leading interactions supported on a single D-brane in […]

Cosmological Constraint on Dark Photon from $N_{rm eff}$

Kavli Affiliate: Satoshi Shirai | First 5 Authors: Masahiro Ibe, Shin Kobayashi, Yuhei Nakayama, Satoshi Shirai, | Summary: A new U(1) gauge symmetry is the simplest extension of the Standard Model and has various theoretical and phenomenological motivations. In this paper, we study the cosmological constraint on the MeV scale dark photon. After the neutrino […]

Balmer Break Galaxy Candidates at $z sim 6$: a Potential View on the Star-Formation Activity at $z gtrsim 14$

Kavli Affiliate: John Silverman | First 5 Authors: Ken Mawatari, Akio K. Inoue, Takuya Hashimoto, John Silverman, Masaru Kajisawa | Summary: We search for galaxies with a strong Balmer break (Balmer Break Galaxies; BBGs) at $z sim 6$ over a 0.41 deg$^2$ effective area in the COSMOS field. Based on rich imaging data, including data […]

Two-Dimensional Forms of Robust CO$_2$ Reduction Photocatalysts

Kavli Affiliate: Kristin A. Persson | First 5 Authors: Steven B. Torrisi, Arunima K. Singh, Joseph H. Montoya, Tathagata Biswas, Kristin A. Persson | Summary: Novel photoelectrocatalysts that use sunlight to power the CO$_2$ reduction reaction will be crucial for carbon-neutral power and energy-efficient industrial processes. Scalable photoelectrocatalysts must satisfy a stringent set of criteria, […]

Identical or fraternal twins? : The chemical homogeneity of wide binaries from Gaia DR2

Kavli Affiliate: Alexander Ji | First 5 Authors: Keith Hawkins, Madeline Lucey, Yuan-Sen Ting, Alexander Ji, Dustin Katzberg | Summary: One of the high-level goals of Galactic archaeology is chemical tagging of stars across the Milky Way to piece together its assembly history. For this to work, stars born together must be uniquely chemically homogeneous. […]
