We introduce a perturbative method to calculate all moments of the first-passage time distribution in stochastic one-dimensional processes which are subject to both white and coloured noise. This class of non-Markovian processes is at the centre of the study of thermal active matter, that is self-propelled particles subject to diffusion. The perturbation theory about the Markov process considers the effect of self-propulsion to be small compared to that of thermal fluctuations. To illustrate…

Run-and-tumble motion in a harmonic potential: field theory and entropy production
Run-and-tumble (RnT) motion is an example of active motility where particles move at constant speed and change direction at random times. In this work we study RnT motion with diffusion in a harmonic

Mean first passage time and absorption probabilities of a Lévy flier on a finite interval: discrete space and continuous limit via Fock space approach
We have extended the Fock space (FS) approach to address the relevant problem of evaluating the mean first passage time (MFPT) and absorption probabilities of a Lévy random particle in a discrete
Dissipation bounds the moments of first-passage times of dissipative currents in nonequilibrium stationary states
We derive generic thermodynamic bounds on the moments of first-passage times of dissipative currents in nonequilibrium stationary states. These bounds hold generically for nonequilibrium stationary


Multidimensional stationary probability distribution for interacting active particles
We derive the stationary probability distribution for a non-equilibrium system composed by an arbitrary number of degrees of freedom that are subject to Gaussian colored noise and a conservative
First passage time densities in non-Markovian models with subthreshold oscillations
Motivated by the dynamics of resonant neurons we consider a differentiable, non-Markovian random process x(t) and particularly the time after which it will reach a certain level xb for the first
Mean first-passage times of non-Markovian random walkers in confinement.
An analytical approach is introduced to calculate the mean first-passage time of a Gaussian non-Markovian random walker to a target in the limit of a large confining volume, and reveals, on the basis of Gaussian processes, the importance of memory effects in first-Passage statistics of non- Markovianrandom walkers in confinement.
Pressure and flow of exponentially self-correlated active particles.
An exact expression is obtained for the steady-state phase-space density of a single Ornstein-Uhlenbeck Particle confined by a quadratic potential, and the result is used to explore more complex geometries, both through analytical approximations and numerical simulations.

A rapidly increasing number of systems is identified in which the stochastic motion of tracer particles follows the Brownian law yet the distribution of particle displacements is strongly
Mean first-passage times in confined media: from Markovian to non-Markovian processes
We review recent theoretical works that enable the accurate evaluation of the mean first passage time (MFPT) of a random walker to a target in confinement for Markovian (memory-less) and
Steady state, relaxation and first-passage properties of a run-and-tumble particle in one-dimension
We investigate the motion of a run-and-tumble particle (RTP) in one dimension. We find the exact probability distribution of the particle with and without diffusion on the infinite line, as well as
Mean first passage time for a class of non-Markovian processes.
The mean first passage time is obtained for CTRW processes with truncated power-law transition time distribution based on the fact that the solutions of the non-Markovian master equation can be obtained via an integral transform from a Markovian Langevin process.
