摘要：
A functional renormalization group approach is applied to a single quantum particle with emphasis on quantum tunnelling through a barrier. We include both an effective potential and a wavefunction renormalization and compare the effects of soft cut-off, hard cut-off and Schwinger proper time regulators. Numerical procedures and results are studied in detail.
