Research Projects, Grant affiliations
Nucleo Mileneo Stochastic Models of Complex and Disordered Systems ( Nucleo website )
The general objective of this Nucleus is to address fundamental questions in the stochastic modeling of disordered and complex systems arising in the natural sciences, social sciences and engineering.
Current Project: RADIAL TRANSFER MATRICES, SPECTRAL THEORY AND DISORDERED SYSTEMS (Fondecyt Regular 2020, Grant 1201836)
Objects of study are certain classes of random Hermitian operators typically with a random potential which can be associated to certain graph structures.
The main questions are about spectrum and spectral transitions.
Here is the abstract of the project.
It is possible to do a Master or a PhD Thesis within this project.
Potential Postdocs are welcome for joint applications of a Fondecyt Postgrado grant within the fields of Spectral Theory, Probability or Dynamical Systems.
Possible research topics for students:
- Radial transfer matrix dynamics of higher dimensional disordered systems
- Dynamics of multiplication of hermitian symplectic sets of matrices
- Critical spectral (energy) regions for one-channel operators
- Spectral properties of certain disordered systems
- Generalized Subordinacy Theory
Work in progress:
- A Deift-Killip theorem for antitrees (with A. Mallick)
- One-channel unitary operators (joint with O. Bourget, G. Moreno and A. Taarabt)
- Spectral and topological properties of the Q-model (joint with G. De Nittis)
- Rotation number of some random hopping model (joint with H. Schulz-Baldes, J. de Moor)
