Engineering Dirac electrons emergent on the surface of a topological insulator
Yukinori Yoshimura, Koji Kobayashi, Tomi Ohtsuki +1
The concept of topological insulator (TI) has introduced a new point of view to condensed-matter physics, relating a priori unrelated subfields such as quantum (spin, anomalous) Ha…
Ultrafast quenching of electron-boson interaction and superconducting gap in a cuprate superconductor
Wentao Zhang, C. Hwang, C. L. Smallwood +9
Ultrafast spectroscopy is an emerging technique with great promise in the study of quantum materials, as it makes it possible to track similarities and correlations that are not ev…
Modification and Control of Topological Insulator Surface States Using Surface Disorder
Vincent Sacksteder, Tomi Ohtsuki, Koji Kobayashi
We numerically demonstrate a practical means of systematically controlling topological transport on the surface of a three dimensional topological insulator, by introducing strong…
Cluster Variables on Certain Double Bruhat Cells of Type and Monomial Realizations of Crystal Bases of Type A
Yuki Kanakubo, Toshiki Nakashima
Let be a simply connected simple algebraic group over , and be two opposite Borel subgroups in and be the Weyl group. For , , it is kno…
On the origin of the narrow peak and the isospin symmetry breaking of the (3872)
Sachiko Takeuchi, Kiyotaka Shimizu, Makoto Takizawa
The (3872) formation and decay processes in the -decay are investigated by a -two-meson hybrid model. The two-meson state consists of the , $D^+D^…
Multiplicity fluctuation from hydrodynamic noise
Tetsufumi Hirano, Ryuichi Kurita, Koichi Murase +1
We discuss multiplicity fluctuation caused by noises during hydrodynamic evolution of the quark-gluon fluid created in high-energy nuclear collisions.
