Kavli Affiliate: Leon Balents | First 5 Authors: Ethan C. McGarrigle, Kris T. Delaney, Leon Balents, Glenn H. Fredrickson | Summary: Recent experiments have shown how the interplay between Bose statistics and spin-orbit coupling (SOC) can lead to superfluid liquid crystalline (stripe) analogues in cold atomic gases. For isotropic SOC in two spatial dimensions, a […]
Kavli Affiliate: Bruce Macintosh | First 5 Authors: Shubh Agrawal, Jean-Baptiste Ruffio, Quinn M. Konopacky, Bruce Macintosh, Dimitri Mawet | Summary: While radial velocity surveys have demonstrated that the population of gas giants peaks around $3~text{au}$, the most recent high-contrast imaging surveys have only been sensitive to planets beyond $sim~10~text{au}$. Sensitivity at small angular separations […]
Kavli Affiliate: Masahito Yamazaki | First 5 Authors: Meer Ashwinkumar, Jacob M. Leedom, Masahito Yamazaki, , | Summary: We discuss the interrelations between several ideas in quantum gravity — holography, the Swampland, and the concept of ensemble averaging. To do so, we study ensemble averages of Narain-type theories associated with general even quadratic forms and […]
Kavli Affiliate: Masahito Yamazaki | First 5 Authors: Meer Ashwinkumar, Jacob M. Leedom, Masahito Yamazaki, , | Summary: We discuss interrelations between several ideas in quantum gravity. One is the Swampland program, which states that a low-energy effective field theory should satisfy non-trivial constraints to have an ultraviolet (UV) completion in quantum gravity. Another is […]
Kavli Affiliate: Satoshi Shirai | First 5 Authors: Katsuki Aoki, Toshifumi Noumi, Ryo Saito, Sota Sato, Satoshi Shirai | Summary: The gravitational positivity bound gives quantitative "swampland” constraints on low-energy effective theories inside theories of quantum gravity. We give a comprehensive discussion of this bound for those interested in applications to phenomenological model building. We […]

Kavli Affiliate: Matthew Fisher | First 5 Authors: Ying-Tian Liu, Zhifei Zhang, Yuan-Chen Guo, Matthew Fisher, Zhaowen Wang | Summary: Automatic generation of fonts can be an important aid to typeface design. Many current approaches regard glyphs as pixelated images, which present artifacts when scaling and inevitable quality losses after vectorization. On the other hand, […]
Kavli Affiliate: Yi Zhou | First 5 Authors: Yi Zhou, Dingpeng Liao, Kun Zhang, Zijie Ma, Shikai Wu | Summary: The far-field resolution of optical imaging systems is restricted by the Abbe diffraction limit, a direct result of the wave nature of light. One successful technological approach to circumventing this limit is to reduce the […]
Kavli Affiliate: Felix Fischer | First 5 Authors: Javier Cembrano, Felix Fischer, Max Klimm, , | Summary: We give new bounds for the single-nomination model of impartial selection, a problem proposed by Holzman and Moulin (Econometrica, 2013). A selection mechanism, which may be randomized, selects one individual from a group of $n$ based on nominations […]
