Tunneling Dynamics and Time Delay in Electron Transport through Time-Dependent Barriers with Finite-Bandwidth Reservoirs
Shmuel Gurvitz, Dmitri Sokolovski
We study a model system consisting of a tunneling barrier driven by an external harmonic field and coupled to two leads with finite bandwidth. Avoiding Floquet expansions, we deriv…

Many-body tunneling in a double-well potential
Matteo Zendra, Fausto Borgonovi, Giuseppe Luca Celardo +1
We present an approach for evaluating Wannier functions, offering an alternative perspective on their role in many-body systems. Unlike traditional methods, such as the maximally l…
