• Optimal Control of Underdamped Systems: An Analytic Approach
  Julia Sanders, Marco Baldovin, Paolo Muratore-Ginanneschi
  

  Motivated by the design of nanoscale electronic components, we find protocols to steer a system between assigned initial and final states, such that a trajectory-dependent cost function is minimized in the underdamped dynamics.

Pre-prints

• Minimal work protocols for inertial particles in non-harmonic traps
  Julia Sanders, Marco Baldovin, Paolo Muratore-Ginanneschi
  

  We approximate the solution of an optimal control problem minimizing mean entropy production in the underdamped dynamics, modelling Landauer's principle at nanoscale.

• On the numerical integration of the Fokker-Planck equation driven by a mechanical force and the Bismut-Elworthy-Li formula
  Julia Sanders, Paolo Muratore-Ginanneschi
  

  A study of Monte Carlo methods that can be used in the numerical integration of PDEs arising in optimal control problems. In particular, we demonstrate the methods with a prototype algorithm for solving a Schrodinger bridge using machine learning.

Talks and Conferences

Talks and Seminars

• Short Introduction to Proximal Operators Mathematical Perspective on Machine Learning, University of Helsinki.
  Proximal operators are used frequently in optimisation because they generalise well to high dimensional problems and work with non-smooth functions. During the seminar, I will introduce the proximal operator and give an overview of its basic properties. I will also give some examples of proximal algorithms for minimisation. Finally, I will illustrate a proximal algorithm (Caluya & Halder 2020) to find a numerical approximation of a solution to Fokker-Planck PDE equation.
