QUANTUM FIELDS PHENOMENA AND INFORMATION GROUP

WELCOME TO THE QUANTUM FIELDS PHENOMENA AND INFORMATION GROUP

The quantum fields phenomena and information group, based at the University of Buenos Aires, deals with the observable consequences of the quantum vacuum fluctuations, mainly in the framework of field theory and open quantum mechanics. One of the most exciting characteristics of quantum field theory is the non-trivial structure of the vacuum state. The idea that the quantum vacuum is a seething sea of fluctuations can be traced back to the early decades of quantum physics. Due to the Heisenberg principle, the zero-energy of the vacuum can never be precisely known so we imagine the quantum vacuum filled by short-lived particles, continuously appearing and disappearing. Evidence has accumulated indicating that this lively vacuum had macroscopic observable consequences such as the modification of the energy between the levels of an atom, known as the Lamb shift, the emergence of effective dispersion forces (Casimir forces) as well as dissipative forces (known as quantum friction) and induced particle creation such as in dynamical Casimir effect. We study the detailed quantitative behavior of these phenomena in situations involving nontrivial geometries that have both conceptual interest and eventual applications in nanotechnology.

QUANTUM GROUPS NETWORK AND JOURNAL CLUB

At the Department of Physics of the university, there is a big and developing network of quantum groups entangling and disentangling to generate new ideas. Our friend group's are the QUFIBA Quantum Foundations and Information Buenos Aires group, dealing with both theoretical and experimental aspects of quantum foundations and quantum information and the Quantum Chaos and Control group, with major focus on quantum control, quantum chaos and the dynamics of open quantum systems.

The entire quantum area celebrates a quantum journal club, where we all meet once a week to discuss recent papers and hot topics of the quantum world. In each meeting, a student is in charge of reviewing the recent relevant international articles and issues, trying to give an overview of the topics. Those presentations can be seen here.
