We investigate the thermodynamic properties of the uniform real-phased submanifold in n-qubit systems, called Hadamard states, represented as a classical ensemble of 2^n spins subject to a potential encoding the multipartite entanglement. For small system sizes (n<6 qubits), we perform an exact enumeration, enabling a complete statistical characterization of the energy landscape and...

In this talk, we will introduce the key differences between bipartite and multipartite entanglement in quantum systems. We will then show how quantum frustration emerges in multipartite scenarios, namely, situations in which a system cannot achieve globally optimal entanglement because different bipartitions impose conflicting requirements.

We present an updated global determination of the neutrino oscillation parameters governing the (ν1 ,ν2 ) sector, including the latest SNO+ results and the first measurement from JUNO. In the three-neutrino framework, we focus on the solar mass splitting δm2 and the mixing parameter sin2θ12 , which drive solar and medium-baseline reactor oscillations.

The Unruh effect predicts that a uniformly accelerated observer in the Minkowski vacuum perceives a thermal bath, so that an accelerating detector behaves as an open quantum system interacting with an effective thermal environment. We exploited this perspective to study entanglement generation between two identical two-level atoms located at the same spacetime point and weakly coupled to the...
