Localizing quantum fields with time-dependent potentials
Boris Ragula, Bruno de S. L. Torres, Erik Schnetter +1
In this paper we study the effect of localizing quantum field degrees of freedom by dynamically growing cavity walls through a time-dependent potential. We use our results to show…

The multimode nature of spacetime entanglement in QFT
Ivan Agullo, Béatrice Bonga, Eduardo MartÃn-MartÃnez +5
We demonstrate the presence of multimode entanglement in the vacuum state of a free, massless scalar quantum field in four-dimensional flat spacetime between two sets of field mode…

Toward a physically motivated notion of Gaussian complexity geometry
Bruno de S. L. Torres, Eduardo MartÃn-MartÃnez
We present a general construction of a geometric notion of circuit complexity for Gaussian states (both bosonic and fermionic) in terms of Riemannian geometry. We lay out general c…
