Entropy Production from Spin--Vibrational Coupling in Endohedral-Fullerene Qubits Encapsulated in Suspended Carbon Nanotubes

Cristian Staii

Spin-vibrational coupling in nanotube-encapsulated fullerene qubits produces crossovers between oscillator-dominated and spin-dominated entropy production.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

magnetic-gradient-enhanced spin-phonon coupling, resonant driving, and moderate thermal occupation produce crossovers between oscillator-dominated and spin-dominated entropy-production regimes.

C2weakest assumption

The system can be accurately described by an effective Jaynes-Cummings spin-vibrational interaction embedded in a Lindblad master equation that includes mechanical damping, spin relaxation, pure dephasing, and thermally activated excitation (abstract, paragraph on the coupled spin-mechanical dynamics).

C3one line summary

A hybrid open-system model using Wigner functions and Lindblad dynamics shows crossovers in entropy-production regimes driven by spin-phonon coupling in fullerene-CNT hybrids.
