Table 3.

At thermal equilibrium, our numerical observations for velocity distribution and temperature of the nanoparticle along with the constraints obtained using various correlated and uncorrelated noise schemes. Abbreviations are MBD: Maxwell-Boltzmann distribution; OUP: Ornstein-Uhlenbeck process; MLN: Mittag-Leffler noise; IT: Iwashita's thermostat.

Thermostat Equilibrium
Thermostat Velocity distribution and equipartition theorem Constraints Implementation remarks
White noise Does not satisfy MBD and equipartition theorem Δt < τb for stability (i) Depends on position and shape of the particle, (ii) does not conform to GLE, and (iii) imbalance between memory and friction
OUP Satisfies MBD and equipartition theorem Δt < τb for stability; τ > τν for thermostat to work (i) Depends on position and shape of the particle and (ii) approximately conforms to GLE
MLN Satisfies MBD and equipartition theorem Δt < τb for stability; τ > τν for thermostat to work; α0(λ) and β0(λ) are independent of τ in a small plateau region where τ ≳ τν (i) Does not depend on position and shape of the particle and (ii) approximately conforms to GLE
IT Satisfies MBD and equipartition theorem Δt < τb for stability (i) Does not depend on position and shape of the particle and (ii) does not conform to GLE
