Teaching
Interactive tools for exploring electronic friction and numerical methods.
Electronic friction
From electronic states to friction
Build an electronic density of states, explore the resulting electron–hole JDOS and friction spectrum, then compare Gaussian broadening treatments near zero frequency. Interactive plots connect each step, with short explanations and rendered equations.
Ring-polymer dynamics and electronic friction
Explore ring-polymer modes by changing bead count and temperature, see how each mode reshapes a friction spectrum, and learn how auxiliary variables encode memory in an A matrix. Includes editable matrix examples, actual offline GLEfit results, and downloadable spectra, kernels and matrices.
Resonant-level electronic friction
Adjust level energy, physical width, temperature and Gaussian broadening. Compare the published equilibrium result and continuum frequency response with single-delta and double-delta broadening prescriptions.
Frictional memory
Explore an exactly solvable harmonic bath. Adjust the memory time, friction strength, and oscillator frequency, then compare the spectrum, motion, and energy with instantaneous friction.
