Esplorazione del ruolo delle correlazioni nell'aumentare l'efficienza asintotica degli interruttori molecolari mediante teorie delle risorse quantistiche

The framework of Quantum Resource Theories has shown great potential to deal with complex physical phenomena when the details of the dynamics are not known. In previous works, the resource theories of thermodynamics have been applied to study the phenomenon of photoisomerization, under which a molecule, excited by an electromagnetic field, can shift to a different spatial configuration. The results showed fundamental limitations on the efficiency of this process and provided indications that correlations contribute to enhancing this efficiency. Here we expand this treatment on photoisomerization, focusing on the effect of correlations when the number of molecules becomes large. We then confront this limit with the thermodynamic limit, in which the free energy is enough to identify the spontaneous transitions that the system can undergo.
