Nonadiabatic landau–zener–stückelberg–majorana transitions, dynamics, and interference

V Ivakhnenko, SN Shevchenko, F Nori - Physics Reports, 2023 - Elsevier
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 …

On the applicability of the Landau-Zener formula to axion-photon conversion

P Carenza, MCD Marsh - Journal of Cosmology and Astroparticle …, 2023 - iopscience.iop.org
Axions and photons resonantly interconvert in regions where the plasma frequency
approximately equals the axion mass. This process is directly analogous to an avoided level …

The Landau–Zener formula made simple

EP Glasbrenner, WP Schleich - Journal of Physics B: Atomic …, 2023 - iopscience.iop.org
We employ the Markov approximation and the well-known Fresnel-integral to derive in'one-

Majorana (LZSM) interferometry in a non-Hermitian N-body interacting boson system in …

Tuning the initial phase to control the final state of a driven qubit

PO Kofman, SN Shevchenko, F Nori - Physical Review A, 2024 - APS
A driven quantum system can experience Landau-Zener-Stückelberg-Majorana (LZSM)
transitions between its states when the respective energy levels quasicross. If this …

Electrical manipulation of the spins in phosphorene double quantum dots

T Thakur, FM Peeters, B Szafran - Scientific Reports, 2024 - nature.com
We investigate electric dipole spin resonance (EDSR) induced by an oscillating electric field
within a system of double quantum dots formed electrostatically in monolayer phosphorene …

Nonlinear Landau-Zener-Stückelberg-Majorana problem

S Ashhab, OA Ilinskaya, SN Shevchenko - Physical Review A, 2022 - APS
In the standard Landau-Zener-Stückelberg-Majorana (LZSM) problem, the bias sweep rate
and gap are both time independent and fully characterize the LZSM problem. We consider …

Progress toward a zero-magnetic-field environment for ultracold-atom experiments

C Rogora, R Cominotti, C Baroni, D Andreoni… - Physical Review A, 2024 - APS
The minimization of the magnetic field plays a crucial role in ultracold gas research. For
instance, the contact interaction dominates all the other energy scales in the zero-magnetic …

Quantum spectral analysis by continuous measurement of Landau-Zener transitions
