Fragile single-cone Dirac quantum walks in two dimensions
C. W. J. Beenakker, J. Sánchez Férnan, J. Sánchez Férnan +2
It is known that a one-dimensional (1D) quantum walk gives a local space-time discretization of the massless Dirac equation with a single quasi-energy cone (no fermion doubling at…

Monitored chaotic scattering
C. W. J. Beenakker, J. Sánchez Fernán, J. Sánchez Fernán +2
We extend the random-matrix theory of chaotic scattering to quantum dots whose dynamics is monitored by time-resolved measurements. Starting from a scattering matrix drawn from a c…

Monitored quantum transport through a disordered one-dimensional conductor
J. Sánchez Fernán, J. TworzydÅo, C. W. J. Beenakker
We formulate a quantum master equation for the many-particle density matrix of electrons propagating through a single-mode conductor, combining elastic scattering by disorder with…
