Spinon band flattening by its emergent gauge field in quantum kagome ice

Masafumi Udagawa, Roderich Moessner

Fractional excitations provide a key to identifying sought-after topological quantum spin liquid states in realistic materials. Their single-particle dynamics already presents a ch…

Superconductivity and Low Energy Excitations in an Attractive Hubbard Model

Yukimi Goto, Tohru Koma, Hironobu Yoshida

We study an attractive Hubbard model on bipartite lattices. In the grand canonical formalism,we prove the existence of superconducting long-range order in the ground state on Lieb…

Hollow Lattice Tensor Gauge Theories with Bosonic Matter

José M. Cruz, Masafumi Udagawa, Pedro Bicudo +2

Higher rank gauge theories are generalizations of electromagnetism where, in addition to overall charge conservation, there is also conservation of higher rank multipoles such as t…

Deflection angle in the strong deflection limit for static and axisymmetric spacetimes: Local curvature, matter fields, and quasinormal modes

Takahisa Igata

We investigate the deflection of photons in the strong deflection limit within static and axisymmetric spacetimes possessing reflection symmetry. As the impact parameter approaches…

Convex structures of the unit tangent spheres in Teichm{ü}ller space

Assaf Bar-Natan, Ken'Ichi Ohshika, Athanase Papadopoulos

We analyse the convex structure of the Finsler infinitesimal balls of the Thurston metric on Teichm{ü}ller space. We analyse the convex structure of the Finsler unit ball in the ta…
