Construction of Many-Body Eigenstates with Displacement Transformations
Miguel Ortuño, Andres M. Somoza, Louk Rademaker
Many-body eigenstates beyond the gaussian approximation can be constructed in terms of local integrals of motion (IOM), although their actual computation has been until now a daunt…

Tunneling time calculations for general finite wavepackets based on the presence time formalism
O. del Barco, M. Ortuño, V. Gasparian
We analyze the tunneling time problem via the presence time formalism. With this method we reproduce previous results for very long wavepackets and we are able to calculate the tun…
