Commensurate-Incommensurate Transition in Submonolayer He on Graphite
A. Kumashita, J. Usami, S. Komatsu +4
We report high-precision heat-capacity measurements of submonolayer He adsorbed on highly crystalline graphite, revealing new aspects of the commensurateincommensurate trans…

Topological phase transition in nonchiral Rice-Mele model with bond disorder
Kiminori Hattori, Kenyu Chikamori, Hayato Iizuka +1
The Rice-Mele model consists of a one-dimensional lattice with two sublattice sites in each unit cell subjected to a staggered sublattice potential. The onsite potential constitute…

Real-space formulation of topology for disordered Rice-Mele chains without chiral symmetry
Kiminori Hattori, Ata Yamaguchi
In this paper, we derive a real-space topological invariant that involves all energy states in the system. This global invariant, denoted by , is always quantized to be 0 or 1,…
