About

I am an Associate Professor in the Physics Department of Instituto Superior Técnico (IST), Universidade de Lisboa, and a researcher at the Center of Physics and Engineering of Advanced Materials (CeFEMA), part of the Laboratory of Physics for Materials and Emerging Technologies (LaPMET). I am also an associate member of the Beijing Computational Science Research Center (CSRC).

• Coordinator of the Quantum Matter Team (q.m@t) at IST.
• Chair of the COST Action CA24109 Many-body Open Quantum Systems (QOpen).
• Coordinator of the Doctoral Programmes in Physics and in Engineering Physics at IST.
• Founding member and one of the coordinators of the Quantum.Matter@PT research network.
• Principal Investigator of the FCT project Scalable Quantum Liouvillian Tomography (2024.16192.PEX).

Research

My research lies at the intersection of condensed matter physics and quantum information, with a particular focus on many-body strong-correlation effects and non-equilibrium processes in open quantum systems. I believe that understanding quantum matter away from equilibrium can guide the design of materials with properties that are unattainable at equilibrium, and can contribute to technologies such as thermoelectrics, sensing devices and quantum information processing.

Current topics of the team:

• Quantum chaos in open systems
• Driven matter and transport
• Quasiperiodic and moiré materials
• Quantum information and noisy devices
• Localization, constraints and gauge theories

Students interested in a BSc, MSc or PhD project are welcome to write to me; see Join us for the current projects.
