The Hydrogen Atom in Strong Electric Fields: Summation of the Weak Field Series Expansion
Ken-ichi Hiraizumi, Yoshihisa Ohshima, Hiroshi Suzuki
The order dependent mapping method, its convergence has recently been proven for the energy eigenvalue of the anharmonic oscillator, is applied to re-sum the standard perturbation…
Calculation Rule for Aoyama-Tamra's Prescription for Path Integral with Quantum Tunneling
Hiroshi Suzuki
We derive a simple calculation rule for Aoyama--Tamra's prescription for path integral with degenerated potential minima. Non-perturbative corrections due to the restricted functio…
Improved Convergence Proof of the Delta Expansion and Order Dependent Mappings
Riccardo Guida, Kenichi Konishi, Hiroshi Suzuki
We improve and generalize in several accounts the recent rigorous proof of convergence of delta expansion - order dependent mappings (variational perturbation expansion) for the en…
BFV-BRST Quantization of 2D Supergravity
T. Fujiwara, Y. Igarashi, R. Kuriki +1
Two-dimensional supergravity theory is quantized as an anomalous gauge theory. In the Batalin-Fradkin (BF) formalism, the anomaly-canceling super-Liouville fields are introduced to…
