Sturm–Liouville systems for the survival probability in first-passage time problems
(2023-11-15)
We derive a Sturm–Liouville system of equations for the exact calculation of the survival probability in first-passage time problems. This system is the one associated with the Wiener–Hopf integral equation obtained from ...
Resource-Efficient High-Dimensional Entanglement Detection via Symmetric Projections
(2023-10-25)
We introduce two families of criteria for detecting and quantifying the entanglement of a bipartite quantum state of arbitrary local dimension. The first is based on measurements in mutually unbiased bases and the second ...
Fire-spotting modelling in operational wildfire simulators based on cellular automata: a comparison study
(2023-07-31)
One crucial mechanism in the spread of wildfires is the so-called fire-spotting: a random phenomenon which occurs when embers are transported over large distances. Fire-spotting speeds up the Rate of Spread and starts new ...
Predicting the arrival of the unpredictable: An approach for foreseeing the transition to chaos of wildfire propagation
(2023-07-07)
A discrete map for modelling wildfire propagation is derived from a prototypical reaction-diffusion equation for the temperature field. We show that, for a constant fuel concentration at the fire-front, the heat transfer ...
Wiener-Hopf Integral Equations in Mean First-passage Time Problems for Continuous-time Random Walks
(2023)
We study the mean first-passage time (MFPT) for asymmetric continuous time random walks in continuous space characterised by finite mean waiting times and jump amplitudes with both finite average and finite variance. We ...
Morning naps architecture and mentation recall complexity
(2023)
Mentation reports were collected after spontaneous awakenings from morning naps in 18 healthy participants, and associations between sleep stages duration and complexity of recalled mentation were investigated. Participants ...
Time Dynamics in Quantum Field Theory Systems
(2022-12-23)
In this doctoral thesis, we develop and investigate new mathematical tools that are intended to allow for a rigorous description of non–perturbative quantum field theory (QFT) dynamics. Here, the term QFT is to be understood ...
Exact calculation of the mean first-passage time of continuous-time random walks by nonhomogeneous Wiener-Hopf integral equations
(2022-12-23)
We study the mean first-passage time (MFPT) for asymmetric continuous-time random walks in continuous-space characterised by waiting-times with finite mean and by jump-sizes with both finite mean and finite variance. In ...
Quantum-enhanced Doppler lidar
(2022-12-01)
We propose a quantum-enhanced lidar system to estimate a target’s radial velocity, which employs squeezed and frequency-entangled signal and idler beams. We compare its performance against a classical protocol using a ...
Bi-Frequency Illumination: A Quantum-Enhanced Protocol
(2022-11-01)
Quantum-enhanced, idler-free sensing protocol to measure the response of a target object to the frequency of a probe in a noisy and lossy scenario is proposed. In this protocol, a target with frequency-dependent reflectivity ...
