Exact WKB analysis for dynamical and geometric exponents in generalized and nonlinear Landau-Zener transitions
Tomohiro Matsuda
The Berry phase is a geometric phase that is important in explaining topological quantum phenomena. The Berry phase is also important in non-perturbative phenomena, as the imaginar…

Quantum field theory on curved manifolds
Tomohiro Matsuda
This paper discusses how particle production from the vacuum can be explained by local analysis when the field theory is defined by differential geometry on curved manifolds. We ha…

How to define the moving frame of the Unruh-DeWitt detector on manifolds
Tomohiro Matsuda
The physical phenomena seen by an observer are defined for a local inertial system that is subjective to the observer. Such a coordinate system is called a ``moving frame'' because…
