Finite modular Coleman-Weinberg inflation
Yoshihiko Abe, Komei Goto, Tetsutaro Higaki +2
We propose a modular symmetric inflationary model based on a Coleman--Weinberg potential generated by integrating out heavy vector-like quarks that couple to the complex modulus fi…
Principal component-guided sparse reduced-rank regression
Kanji Goto, Shintaro Yuki, Kensuke Tanioka +1
Reduced-rank regression estimates regression coefficients by imposing a low-rank constraint on the matrix of regression coefficients, thereby accounting for correlations among resp…
Kondo effect under arbitrary spin-momentum locking
Kinari Goto, Yusuke Nishida
The Kondo effect originates from the spin exchange scattering of itinerant electrons with a localized magnetic impurity. Here, we consider generalization of Weyl-type electrons wit…
Moduli stabilization in finite modular symmetric models
Yoshihiko Abe, Komei Goto, Testutaro Higaki +2
We study vacua of moduli potential consisting of multiple contribution of modular forms in a finite modular symmetry. If the potential is given by a single modular form, the Minkow…
