Spin Chains from large- QCD at strong coupling
David Berenstein, Hiroki Kawai
We study the strong coupling expansion of large QCD in various dimensions, reformulating the Kogut-Susskind Hamiltonian on a square lattice in terms of (constrained) one dimens…
Integrability and Conformal Blocks for Surface Defects in SYM
Adolfo Holguin, Hiroki Kawai
We study various aspects of half-BPS surface defect operators in SYM. For defects on generic points on the moduli space we use superconformal symmetry to fix the fo…
Galaxy-galaxy strong lensing cross-section with fuzzy dark matter model
Hiroki Kawai, Massimo Meneghetti
The galaxy-galaxy strong lensing (GGSL) cross-section in observed galaxy clusters has been reported to be more than an order of magnitude higher than the theoretical prediction by…
X-ray/H scaling relationships in stellar flares
Hiroki Kawai, Yohko Tsuboi, Wataru B. Iwakiri +5
We report on the results of our simultaneous observations of three large stellar flares with soft X-rays (SXRs) and an H emission line from two binary systems of RS CVn t…
The RS CVn type star GT Mus shows most energetic X-ray flares throughout the 2010s
Ryo Sasaki, Yohko Tsuboi, Wataru Iwakiri +14
We report that the RS CVn-type star GT Mus (HR 4492, HD 101379 + HD 101380) was the most active star in the X-ray sky in the last decade in terms of the scale of recurrent energeti…
Optical and X-ray observations of stellar flares on an active M dwarf AD Leonis with Seimei Telescope, SCAT, NICER and OISTER
Kosuke Namekata, Hiroyuki Maehara, Ryo Sasaki +24
We report multi-wavelength monitoring observations of an M-dwarf flare star AD Leonis with Seimei Telescope (6150--7930 Å), SCAT (Spectroscopic Chuo-university Astronomical Telesco…
VAE/WGAN-Based Image Representation Learning For Pose-Preserving Seamless Identity Replacement In Facial Images
Hiroki Kawai, Jiawei Chen, Prakash Ishwar +1
We present a novel variational generative adversarial network (VGAN) based on Wasserstein loss to learn a latent representation from a face image that is invariant to identity but…
