Physical spin torques from exactly constrained exchange-correlation torques
Jacques K. Desmarais, Kamel Bencheikh, Giovanni Vignale +1
The problem of capturing physical spin torques in non-collinear magnetic systems has dominated the scene of spin-density functional theory (SDFT) in the last two decades. Progress…

Analytic solution to degenerate biphoton states generated in arrays of nonlinear waveguides
Jefferson Delgado-Quesada, David Barral, Kamel Bencheikh +1
The arrays of nonlinear waveguides are a powerful integrated photonics platform for studying and manipulating quantum states of light. Also, they are a valuable resource for variou…
