Destined never to relax: a theoretical study on quantum systems

According to classical physics, the universe tends to equilibrium but the same does not apply to quantum systems, which are destined to shift constantly between different configurations without ever finding peace. A theoretical study conducted by SISSA and the University of Oxford illustrates this dramatic difference and explains that in order to be described correctly one-dimensional quantum systems should be thought of as being defined on discrete points in space.

L’universo, secondo la fisica classica tende all’equilibrio, ma questo non accade per i sistemi quantistici, destinati ad altalenare costantemente fra diverse configurazioni, senza trovare mai pace. Uno studio teorico condotto dalla SISSA e dall’Università di Oxford mostra questa drastica differenza e spiega che i sistemi quantistici unidimensionali, per essere descritti con precisione, devono essere pensati come definiti su punti discreti dello spazio.
