Since the pioneering works by Landau, Zener, Stückelberg, and Majorana (LZSM), it has
been known that driving a quantum two-level system results in tunneling between its states …

Many important phenomena in quantum devices are dynamic, meaning that they cannot be
studied using time-averaged measurements alone. Experiments that measure such transient …

A quantum two-level system with periodically modulated energy splitting could provide a
minimal universal quantum heat machine. We present the experimental realization and the …

Whether genuine quantum effects, particularly quantum coherences, can offer an advantage
to quantum devices is a topic of much interest. Here, we study a minimal model, the three …

We investigate the Landau-Zener-Stückelberg-Majorana interferometry of a
superconducting qubit in a semi-infinite transmission line terminated by a mirror. The …

In this work, we derive exact solutions of a dynamical equation, which can represent all two-
level Hermitian systems driven by periodic N-step driving fields. For different physical …

We theoretically describe a driven two-electron four-level double-quantum dot (DQD) tunnel
coupled to a fermionic sea using the rate-equation formalism. This approach allows to find …

Strong driving of quantum systems opens opportunities for both controlling and
characterizing their states. For theoretical studying of these systems properties we use the …

Exact formulas are derived for systems involving Landau-Zener transition rates and for
absorption spectra in quantum dots. These rectify previous inaccurate approximations …

In Si quantum dots, the valley degree of freedom, in particular the generally small valley
splitting and the dot-dependent valley-orbit phase, adds complexities to the low-energy …
