Kavli Affiliate: Dheeraj Pasham | First 5 Authors: Dheeraj Pasham, Shubham Kejriwal, Eric Coughlin, Vojtěch Witzany, Alvin J. K. Chua | Summary: Quasi-periodic eruptions (QPEs) are recurring bursts of soft X-rays from the nuclei of galaxies. Their physical origin is currently a subject of debate, with models typically invoking an orbiter around a massive black […]
Kavli Affiliate: Mihoko M. Nojiri | First 5 Authors: Rafał Masełek, Mihoko M. Nojiri, Kazuki Sakurai, , | Summary: The system of light electroweakinos and heavy squarks gives rise to one of the most challenging signatures to detect at the LHC. It consists of missing transverse energy recoiled against a few hadronic jets originating either […]
Kavli Affiliate: Jing Wang | First 5 Authors: Fu Feng, Yucheng Xie, Jing Wang, Xin Geng, | Summary: Creativity, both in human and diffusion models, remains an inherently abstract concept; thus, simply adding "creative" to a prompt does not yield reliable semantic recognition by the model. In this work, we concretize the abstract notion of […]
Kavli Affiliate: Jing Wang | First 5 Authors: Fu Feng, Yucheng Xie, Xu Yang, Jing Wang, Xin Geng | Summary: “Creative” remains an inherently abstract concept for both humans and diffusion models. While text-to-image (T2I) diffusion models can easily generate out-of-domain concepts like “a blue banana”, they struggle with generating combinatorial objects such as “a […]
Kavli Affiliate: Ulrich Sperhake | First 5 Authors: Bo-Xuan Ge, Eugene A. Lim, Ulrich Sperhake, Tamara Evstafyeva, Daniela Cors | Summary: We explore the gravitational-wave emission from head-on collisions of equal-mass solitonic boson-star binaries from simulations spanning a two-dimensional parameter space, consisting of the central scalar-field amplitude of the stars and the solitonic potential parameter. […]
Kavli Affiliate: Savdeep Sethi | First 5 Authors: Gabriel Weiderpass, Mayur Sharma, Savdeep Sethi, , | Summary: A wide range of non-equilibrium phenomena in nature involve non-reciprocal interactions. To understand the novel behaviors that can emerge in such systems, finding tractable models is essential. With this goal, we introduce a non-reciprocal generalization of the kinetic […]
Kavli Affiliate: Savdeep Sethi | First 5 Authors: Gabriel Weiderpass, Mayur Sharma, Savdeep Sethi, , | Summary: Non-reciprocal interactions are a generic feature of non-equilibrium systems. We define a non-reciprocal generalization of the kinetic Ising model in one spatial dimension. We solve the model exactly using two different approaches for infinite, semi-infinite and finite systems […]
Kavli Affiliate: Gordan Krnjaic | First 5 Authors: Kylar Greene, Aurora Ireland, Gordan Krnjaic, Yuhsin Tsai, | Summary: A B-mode polarization signal in the cosmic microwave background is widely regarded as smoking gun evidence for gravitational waves produced during inflation. Here we demonstrate that tensor perturbations from a cosmological phase transition in the post-inflationary universe […]
Kavli Affiliate: T. Higuchi | First 5 Authors: Belle, Belle II Collaborations, :, I. Adachi, L. Aggarwal | Summary: We perform a model-independent measurement of the $D^0$-$overline{D}{}^0$ mixing parameters using samples of $e^+e^-$-collision data collected by the Belle and Belle II experiments that have integrated luminosities of $951 text{fb}^{-1}$ and $408 text{fb}^{-1}$, respectively. Approximately $2.05times10^6$ […]
Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Thomas C. Abbott, Andrew V. Zwaniga, Charanjot Brar, Victoria M. Kaspi, Emily Petroff | Summary: We present frb-voe, a publicly available software package that enables radio observatories to broadcast fast radio burst (FRB) alerts to subscribers through low-latency virtual observatory events (VOEvents). We describe a use-case […]
