Partial Dynamical Symmetries and Rotation-Vibration Interactions in deformed nuclei and notes on the dangers of statistical tests of nuclear models

A) Partial Dynamical Symmetries and Rotation-Vibration Interactions in deformed nuclei Traditionally, B(E2) transitions in deformed nuclei have been interpreted in terms of the Alaga rules and bandmixing. Recently a new approach, called Partial Dynamical Symmetries, apparently based on entirely different physics ideas, has been shown to work quite well also. These results will be introduced and shown, along with a very simple derivation that relates the two models to each other.

Neuroimaging and Innovative Labeling Strategies

After a brief introduction on the activities of the Commissariat à l’Energie Atomique et aux energies alternatives (CEA) in defence and security, nuclear energy, technological research for industry, fundamental research in the physical sciences and life sciences, I will give an overview of the researches that are conducted by the Imagerie Moléculaire In Vivo unit (IMIV) hosted at the Service Hospitalier Frédéric Joliot. My presentation will focus on three main topics of research conducted in collaboration between the four teams of the IMIV unit:

In the 100 plus years since Einstein formulated general relativity, his theory has proven truly remarkable in the scope and breadth of its predictions concerning the gravitational interaction and the degree to which those predictions are borne out by experiment and observation.

When the Universe was Hot and Sticky

The phase diagram of Quantum Chromodynamics (QCD, the theory of the strong interaction) is only poorly known. There are currently vibrant experimental and theoretical programs that concentrate on the production, study, and characterization of the quark-gluon plasma: a fundamental state of matter that existed a few microseconds after the Big Bang. I will describe the theoretical aspects of this endeavour, and highlight some of the surprises uncovered along the way.

The eigenstate thermalization hypothesis (ETH) holds that the energy eigenstates underlying an evolving superposition mimic thermal states of the system [1, 2]. Thus, in this picture - despite the deterministic nature of the Schroedinger equation and the absence of outside perturbations - an arbitrarily prepared isolated quantum system relaxes to a thermal equilibrium that is somehow hardwired in its eigenstates. Indeed, ergodic dynamics have been found in a quantum system as small as three transmon qubits [3].
