Quantum Zeno effect: Quantum shuffling and Markovianity
A. S. Sanz, C. Sanz-Sanz, T. Gonzalez-Lezana +2
The behavior displayed by a quantum system when it is perturbed by a series of von Neumann measurements along time is analyzed. Because of the similarity between this general proce…
Zeno dynamics in wave-packet diffraction spreading
M. A. Porras, A. Luis, I. Gonzalo +1
We analyze a simple and feasible practical scheme displaying Zeno, anti-Zeno, and inverse-Zeno effects in the observation of wave-packet spreading caused by free evolution. The sch…
Revisiting Zeno's paradox: Flying arrows for atom-diatom reactions
C. Sanz-Sanz, A. S. Sanz, T. Gonzalez-Lezana +2
The possibility to observe quantum Zeno and anti-Zeno scenarios for atom-diatom reactive collisions is investigated for two diferent processes (F+HD and H+O_2) by means of time-dep…
Quantum Zeno-based control mechanism for molecular fragmentation
C. Sanz-Sanz, A. S. Sanz, T. Gonzalez-Lezana +2
A quantum control mechanism is proposed for molecular fragmentation processes within a scenario grounded on the quantum Zeno effect. In particular, we focus on the van der Waals Ne…
Investigating transition state resonances in the time domain by means of Bohmian mechanics: The F+HD reaction
A. S. Sanz, D. Lopez-Duran, T. Gonzalez-Lezana
In this work, we investigate the existence of transition state resonances on atom-diatom reactive collisions from a time-dependent perspective, stressing the role of quantum trajec…
Setting up tunneling conditions by means of Bohmian mechanics
A. S. Sanz, S. Miret-Artes
Usually tunneling is established after imposing some matching conditions on the (time-independent) wave function and its first derivative at the boundaries of a barrier. Here an al…
Quantum phase analysis with quantum trajectories: A step towards the creation of a Bohmian thinking
A. S. Sanz, S. Miret-Artes
We introduce a pedagogical discussion on Bohmian mechanics and its physical implications in connection with the important role played by the quantum phase in the dynamics of quantu…
Quantum Zeno and anti-Zeno effects in surface diffusion of interacting adsorbates
H. C. Pennate-Rodriguez, R. Martinez-Casado, G. Rojas-Lorenzo +2
Surface diffusion of interacting adsorbates is here analyzed within the context of two fundamental phenomena of quantum dynamics, namely the quantum Zeno effect and the anti-Zeno e…
