## Self-adjoint extension in quantum mechanics and non-Rydberg spectra of one-dimensional hydrogen atom

April 13 at 16:00 - 18:10, 2021

Prof. Taksu Cheon (Professor, School of Environmental Science and Engineering, Kochi University of Technology)

We offer a beginner’s guide to the functional-analytical techniques in quantum mechanics, and cover its application to the 1D Coulomb problem. It is shown that the wave function at the diverging poin...more

## Non-perturbative tests of duality cascades in three dimensional supersymmetric gauge theories

December 14 at 16:00 - 18:10, 2020

Dr. Naotaka Kubo (Postdoctoral Researcher, Yukawa Institute for Theoretical Physics, Kyoto University)

M2-brane is an interesting object in M-theory and string theory. A three-dimensional 𝒩=6 super conformal Chern Simons theory with gauge group U(𝑁1)×𝑈(𝑁2), called ABJ theory, describes the low energy b...more

## Mathematics of thermalization in isolated quantum systems

November 10 at 16:00 - 18:10, 2020

Dr. Naoto Shiraishi (assistant professor, Faculty of Science Department of Physics, Gakushuin University)

If an isolated macroscopic quantum system is left at a nonequilibrium state, then this system will relax to the unique equilibrium state, which is called thermalization. Most of quantum many-body syst...more

## TQFT, integrable lattice model, and quiver gauge theories

October 2 at 16:00 - 18:00, 2020

Mr. Toshihiro Ota (Student Trainee, iTHEMS)

- 1st part (math): In physics literature, “lattice models” appear quite often as mathematical models of physical systems, e.g. Ising model, vertex models, lattice gauge theory. The aim of the 1st part...more
