Kavli Affiliate: Yukinobu Toda | First 5 Authors: Tudor Pădurariu, Yukinobu Toda, , , | Summary: In previous work, we studied quasi-BPS categories (of symmetric quivers with potential, of preprojective algebras, of surfaces) and showed they have properties analogous to those of BPS invariants/ cohomologies. For example, quasi-BPS categories are used to formulate categorical analogues […]
Kavli Affiliate: Yukinobu Toda | First 5 Authors: Tudor Pădurariu, Yukinobu Toda, , , | Summary: In previous works, we introduced and studied certain categories called quasi-BPS categories associated to symmetric quivers with potential, preprojective algebras, and local surfaces. They have properties reminiscent of BPS invariants/ cohomologies in enumerative geometry, for example they play important […]
Kavli Affiliate: Yukinobu Toda | First 5 Authors: Tudor Pădurariu, Yukinobu Toda, , , | Summary: We study certain categories associated to symmetric quivers with potential, called quasi-BPS categories. We construct semiorthogonal decompositions of the categories of matrix factorizations for moduli stacks of representations of (framed or unframed) symmetric quivers with potential, where the summands […]
Kavli Affiliate: Jia Liu | First 5 Authors: Moyan Li, Jinmiao Fu, Shaoyuan Xu, Huidong Liu, Jia Liu | Summary: On shopping websites, product images of low quality negatively affect customer experience. Although there are plenty of work in detecting images with different defects, few efforts have been dedicated to correct those defects at scale. […]
Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: Garv Chauhan, Shunsaku Horiuchi, Patrick Huber, Ian M. Shoemaker, | Summary: Sterile neutrinos can be produced through mixing with active neutrinos in the hot and dense core of a core-collapse supernova (SN). The standard bounds on the active-sterile mixing ($sin^2 theta$) from SN arise from SN1987A energy-loss, […]
Kavli Affiliate: Tadayuki Takahashi | First 5 Authors: Hiroki Yoneda, Felix Aharonian, Paolo Coppi, Thomas Siegert, Tadayuki Takahashi | Summary: De-excitation gamma-ray lines, produced by nuclei colliding with protons, provide information about astrophysical environments where particles have kinetic energies of $10-100$ MeV per nucleon. In general, such environments can be categorized into two types: the […]
Kavli Affiliate: Hirosi Ooguri | First 5 Authors: Yuya Kusuki, Sara Murciano, Hirosi Ooguri, Sridip Pal, | Summary: We perform a comprehensive analysis of the symmetry-resolved (SR) entanglement entropy (EE) for one single interval in the ground state of a $1+1$D conformal field theory (CFT), that is invariant under an arbitrary finite or compact Lie […]

Kavli Affiliate: Jia Liu | First 5 Authors: Shuailiang Ge, Jinhui Guo, Jia Liu, , | Summary: We present a novel mechanism for the primordial black hole (PBH) production within the QCD axion framework. We take the case where the Peccei-Quinn symmetry breaks during inflation, resulting in a $N_{rm DW}=1$ string-wall network that re-enters horizon […]
Kavli Affiliate: Jia Liu | First 5 Authors: Mingxuan Du, Jia Liu, Xiao-Ping Wang, Tianhao Wu, | Summary: We investigate the enhancement of dark sector particle production within the scattering dominant regime. These particles typically exhibit a slight mixing with Standard Model particles through various portals, allowing for their generation through in-medium oscillation from Standard […]
