Quantum matrix geometry in the lowest Landau level and higher Landau levels
Kazuki Hasebe
One of the most celebrated works of Professor Madore is the introduction of fuzzy sphere. I briefly review how the fuzzy two-sphere and its higher dimensional cousins are realized…
Landau Model and 4D Quantum Hall Effect in The Monopole Background
Kazuki Hasebe
We investigate the Landau problem in the monopole gauge field background by applying the techniques of the non-linear realization of quantum field theory. The $SO(4…
Spin-entangled Squeezed State on a Bloch Four-hyperboloid
Kazuki Hasebe
The Bloch hyperboloid underlies the quantum geometry of the original squeezed states. In \cite{Hasebe-2019}, the author utilized a non-compact 2nd Hopf map and a Bl…
A Unified Construction of Skyrme-type Non-linear sigma Models via The Higher Dimensional Landau Models
Kazuki Hasebe
A curious correspondence has been known between Landau models and non-linear sigma models: Reinterpreting the base-manifolds of Landau models as field-manifolds, the Landau models…
Landau Models and Nested Nambu Matrix Geometry
Kazuki Hasebe
The Landau model is the mathematical platform of the 4D quantum Hall effect and provide a rare opportunity for a physical realization of the fuzzy four-sphere. We present a…
Squeezing for Bloch Four-Hyperboloid via The Non-Compact Hopf Map
Kazuki Hasebe
We explore the hyperbolic geometry of squeezed states in the perspective of the non-compact Hopf map. Based on analogies between squeeze operation and hyperbolic…
