Ricerca

Posso dire con sicurezza che nessuno Lo scopo del calcolo è la comprensione
capisce la meccanica quantistica.  intuitiva non i numeri.
Richard P. Feynman       Richard Hammings


 La mia ricerca riguarda la teoria e l’applicazione degli algoritmi di simulazione numerica al computer per predire le proprietà dipendenti dal tempo di sistemi classici e quantistici di spin. In particolare, studio nei seguenti settori: Dinamica quantistica con Hamiltoniane non-Hermitian, formulazione di approcci teorici ed algoritmici per simulare la dinamica dei sistemi quantità in ambienti classici, la dinamica nonadiabatica dei sistemi quanto-classici, e la formulazione generale dei vincoli termodinamici in meccanica statistica.

  • Superfluidity e coerenza quantistica macroscopica (dal 2018).

Esperienza di Insegnamento e Supervisione
 

L’insegnamento non è   La funzione dell’istruzione e di insegnare a ciascuno
il riempimento di un secchio,   a pensare intensamente e in maniera critica. Intelligenza
ma l’accensione di un fuoco.   più carattere - questo è lo scopo della vera istruzione.

    Research

    I can safely say that  The purpose of computing is insight
    nobody understands quantum mechanics.   not numbers.
    Richard P. Feynman  Richard Hammings


    My research regards both the theory and the application  of computer simulation methods to calculate time-dependent properties in quantum and classical spin systems. I am particularly active in the following areas: Quantum dynamics with non-Hermitian Hamiltonians, the development of theory and algorithms to simulate  the dynamics of open quantum system in classical environments, nonadiabatic dynamics in quantum-classical systems, and the general formulation of thermodynamic constraints in statistical mechanics.

    Teaching and Supervising Experience

    Eduction is not  The function of education is to teach one to think
