Physics Colloquium: Prof. Dr. Gustavo Scuseria: Exploiting Dualities for Strong Correlation
Rice University, Department of Chemistry and Department of Physics and Astronomy, Houston, Texas, USA
In recent years, my research group has focused on strong electron correlation, a problem that after almost 100 years of Schrodinger equation, remains pervasive and hinders many practical applications.
In this talk, I will discuss our recent efforts to tackle it using dualities that convert strongly correlated systems into more weakly correlated ones. String operators, such as those appearing in the Jordan-Wigner transformation when mapping fermions to qubits, play a central role in the theory. String operators are responsible for the algebra transmutation between fermions and spin ½ (hardcore bosons). Despite their nonlocal and many-body characteristics, matrix elements of string operators can be obtained with low polynomial computational cost in classical computers.
I will present proof of principle applications of the theory to modeling strongly correlated spin systems as fermions.
