Sampling strategies for the Herman-Kluk propagator of the wavefunction
Fabian Kröninger, Caroline Lasser, Jiří Vaníček
When the semiclassical Herman-Kluk propagator is used for evaluating quantum-mechanical observables or time-correlation functions, the initial conditions for the guiding trajectori…
A time-reversible integrator for the time-dependent Schrödinger equation on an adaptive grid
Seonghoon Choi, Jiří Vaníček
One of the most accurate methods for solving the time-dependent Schrödinger equation uses a combination of the dynamic Fourier method with the split-operator algorithm on a tensor-…
Path integral approach to the quantum fidelity amplitude
Jiri Vanicek, Doron Cohen
The Loschmidt echo is a measure of quantum irreversibility and is determined by the fidelity amplitude of an imperfect time-reversal protocol. Fidelity amplitude plays an important…
Monte Carlo evaluation of the equilibrium isotope effects using the Takahashi-Imada factorization of the Feynman path integral
Marcin Buchowiecki, Jiri Vanicek
The Feynman path integral approach for computing equilibrium isotope effects and isotope fractionation corrects the approximations made in standard methods, although at significant…
Imaginary-time nonuniform mesh method for solving the multidimensional Schrodinger equation: Fermionization and melting of quantum Lennard-Jones crystals
Alberto Hernando, Jiri Vanicek
An imaginary-time nonuniform mesh method is presented and used to find the first 50 eigenstates and energies of up to five strongly interacting spinless quantum Lennard-Jones parti…
Beating the efficiency of both quantum and classical simulations with semiclassics
Cesare Mollica, Jiri Vanicek
While rigorous quantum dynamical simulations of many-body systems are extremely difficult (or impossible) due to the exponential scaling with dimensionality, corresponding classica…
