Geometric driving of two-level quantum systems
(American Physical Society, 2020)
We investigate a class of cyclic evolutions for driven two-level quantum systems (effective spin 1/2) with a particular focus on the geometric characteristics of the driving and their specific imprints on the quantum ...

Magnetic switching of spin-scattering centers in Dresselhaus [110] circuits
(American Physical Society, 2024-01-24)
Spin carriers subject to Dresselhaus [110] (D110) spin-orbit coupling (SOC) gather null spin phases in closed circuits, contrary to usual Rashba and Dresselhaus [001] SOC. We show that D110 spin phases can be activated in ...

Chiral spin channels in curved graphene pn junctions
(American Physical Society, 2023-09-20)
We show that the chiral modes in circular graphene pn junctions provide an advantage for spin manipulation via spin-orbit coupling compared to semiconductor platforms. We derive the effective Hamiltonian for the spin ...

Nonmonotonic quantum phase gathering in curved spintronic circuits
(American Physical Society, 2021-11-24)
Spin carriers propagating along quantum circuits gather quantum spin phases depending on the circuit’s size, shape, and spin-orbit coupling (SOC) strength. These phases typically grow monotonically with the SOC strength, ...

Quantum network approach to spin interferometry driven by Abelian and non-Abelian fields
(2021-04-21)
We present a theory of conducting quantum networks that accounts for Abelian and non-Abelian fields acting on spin carriers. We apply this approach to model the conductance of mesoscopic spin interferometers of different ...

Casimir‐Lifshitz optical resonators: a new platform for exploring physics at the nanoscale
(Wiley, 2024-02)
The Casimir-Lifshitz force, FC − L, has become a subject of great interest to both theoretical and applied physics communities due to its fundamental properties and potential technological implications in emerging nano-scale ...

Spin-texture topology in curved circuits driven by spin-orbit interactions
(Nature Research, 2023-07-22)
Interferometry is a powerful technique used to extract valuable information about the wave function of a system. In this work, we study the response of spin carriers to the effective field textures developed in curved ...
