The paper models a two-level system due to an impurity in an antiferromagnetic cluster and interacting with the phonon and magnon cloud or their coupling (so-called f-quantum-noise field) forming the so-called blended ferron which is subjected to an

This paper investigates the thermal energy effect on electron auto-localization. The polaron characteristics (self-action potential and effective mass) are observed to be expressed via the renormalized electron-phonon coupling constant tailored by th

This paper presents a simple Josephson-junction circuit with two parameters (inductance and capacitance) which can be tuned to represent different energy landscapes with different physical properties. By tuning this quantum circuit through external a

We study the Landau Zener (LZ) dynamics of a two-site Heisenberg spin chain assisted with noise and focus on the implementation of logic gates via the resulting quantum interference. We present the evidence of the quantum interference phenomenon in t

The paper presents a weak coupling polaron in a spherical dot with magnetic impurities and investigates conditions for which the system mimics a qubit. Particularly, the work focuses on the Landau-Zener (LZ) scenario undergone by the polaron and deri

This paper presents an all-coupling approach (dynamic matrix approach (DMA)) for the description of polaron regimes. The model under investigation is based on an ionic crystal in which the electron-phonon coupling is modified by thermal excitations.

The paper presents the magnetic field effects on an electron in a QD and focuses on spin-orbital coupling and coloured noise assisted Landau-Zener (LZ) transition applying the Dynamic matrix approach (DMA). The system is shown to imitate a noisy driv

The paper investigates the multi-crossing dynamics of a Landau–Zener (LZ) system driven by two sinusoidal a.c fields applying the Dynamic Matrix approach (DMA). The system is shown to follow one-crossing and multi-crossing dynamics for low and high

The paper investigates multi-crossing dynamics of two-level Landau Zener (LZ) systems applying Dynamic matrix approach (DMA) and shows the two-level (multi-crossing) model to tailor qubits. The paper derives the probabilities for different multi-cros
