Parabolic model with phase-jump coupling
Jaakko Lehto, Kalle-Antti Suominen
We study the coherent dynamics of a two-level parabolic model and ways to enhance population transfer and even to obtain complete population inversion in such models. Motivated by…
Time-dependent two-level models and zero-area pulses
Jaakko Lehto, Kalle-Antti Suominen
Time-dependent two-level models have been an important element in physics, and in particular in quantum optics since 1930's. We review the basics of these models and focus on the d…
Geometry of adiabatic Hamiltonians for two-level quantum systems
Jaakko Lehto, Kalle-Antti Suominen
We present the formulation of the problem of the coherent dynamics of quantum mechanical two-level systems in the adiabatic region in terms of the differential geometry of plane cu…
Superparabolic Level Glancing Models for Two-State Quantum Systems
J. Lehto, K. -A. Suominen
Level crossing models for two-state quantum systems are applicable to a wide variety of physical problems. We address the special case of level glancing, i.e., when energy levels r…
Non-Markovian waiting time distribution
Kimmo Luoma, Kari Härkönen, Sabrina Maniscalco +2
Simulation methods based on stochastic realizations of state vector evolutions are commonly used tools to solve open quantum system dynamics, both in the Markovian and non-Markovia…
Connecting two jumplike unravelings for non-Markovian open quantum systems
Kimmo Luoma, Kalle-Antti Suominen, Jyrki Piilo
The development and use of Monte Carlo algorithms plays a visible role in the study of non-Markovian quantum dynamics due to the provided insight and powerful numerical methods for…
