# Dzyaloshinskii-Moriya and dipole-dipole interactions affect coupling-based Landau-Majorana-Stückelberg-Zener transitions

@article{Grimaudo2020DzyaloshinskiiMoriyaAD, title={Dzyaloshinskii-Moriya and dipole-dipole interactions affect coupling-based Landau-Majorana-St{\"u}ckelberg-Zener transitions}, author={Roberto Grimaudo and Hiromichi Nakazato and Antonino Messina and Nikolay V. Vitanov}, journal={arXiv: Quantum Physics}, year={2020} }

It has been theoretically demonstrated that two spins (qubits or qutrits), coupled by exchange interaction only, undergo a coupling-based joint Landau-Majorana-Stuckelberg-Zener (LMSZ) transition when a linear ramp acts upon one of the two spins. Such a transition, under appropriate conditions on the parameters, drives the two-spin system toward a maximally entangled state. In this paper, effects on the quantum dynamics of the two qudits, stemming from the Dzyaloshinskii-Moriya (DM) and dipole…

This paper demonstrates the effectiveness of a proposed protocol for engineering non-Hermitian Hamiltonians as a result of repetitive measurements on an ancillary qubit by applying it to physically relevant multi-spin models, and reports a new recipe to construct a physical scenario where the quantum dynamics of a physical system represented by a given non- herMITian Hamiltonian model may be simulated.
