Velocity modulus diffusion of self-propelled spherical and circular particles: A generalized Langevin approach
Pedro J. Colmenares
This research presents a framework for describing the average velocity magnitude of an accelerated, self-propelled Brownian particle diffusing in a thermal fluid and confined by a…
Adiabatic protocol for the generalized Langevin equation
Pedro J. Colmenares
This article proposes a self-consistent methodology for determining the mechanical adiabatic work of Brownian particles trapped in optical tweezers. Rather than varying the trap fr…
Optimal work of Brownian motion in a harmonic time-dependent stiffness potential. Effect of the initial position
Pedro J. Colmenares, Oscar Paredes-Altuve
The system consists of a Brownian particle immersed in a heat bath trapped in optical tweezers with a time-dependent strength acting as an external protocol. In [Phys. Rev. Letts.,…

This article discusses the numerical result predicted by the quantum Langevin equation of the generalized diffusion function of a Brownian particle immersed in an Ohmic quantum bat…
Thermodynamic work associated to quantum Brownian motion in an external field
Pedro J. Colmenares
This work focuses on the response to an external field of a Brownian particle submerged in an Ohmic quantum thermal bath. The field only affects the dynamics of the central particl…
Fokker-Planck equation of the reduced Wigner function associated to an Ohmic quantum Langevin dynamics
Pedro J. Colmenares
This article has to do with the derivation and solution of the Fokker--Planck equation associated to the momentum-independent Wigner function, of a particle subjected to a harmonic…
Extracting work from a single reservoir in the non-Markovian underdamped regime
Oscar Paredes-Altuve, Ernesto Medina, Pedro J. Colmenares
We derive optimal-work finite time protocols for a colloidal particle in a Gaussian well in the general non-Markovian underdamped regime in contact with a single reservoir. Optimal…
The generalized Langevin equation revisited: Analytical expressions for the persistence dynamics of a viscous fluid under a time dependent external force
Wilmer Olivares-Rivas, Pedro J. Colmenares
The non--static generalized Langevin equation and its corresponding Fokker--Planck equation for the position of a viscous fluid particle were solved in closed form for a time depen…
On the Scaling of Langevin and Molecular Dynamics Persistence Times of Non-Homogeneous Fluids
Wilmer Olivares-Rivas, Pedro J. Colmenares
The solution of the Langevin equation of an anisotropic fluid [Colmenares P. J; López F. and Olivares-Rivas W., Phys. Rev E. 2009, 80061123] allowed the evaluation of the position…
