Attractors and asymptotic dynamics of open discrete-time quantum walks on cycles
Adam S. Sajna, Tomasz P. Polak, Antoni Wojcik +1
Open quantum walks often lead to a classical asymptotic behavior. Here, we look for a simple open quantum walk whose asymptotic behavior can be non-classical. We consider a discret…
Assembly of 2N entangled fermions into multipartite composite bosons
Zakarya Lasmar, P. Alexander Bouvrie, Adam S. Sajna +2
An even number of fermions can behave in a bosonic way. The simplest scenario involves two fermions which can form a single boson. But four fermions can either behave as two bipart…
On dynamical stability of composite quantum particles: when entanglement is enough and when interaction is needed
Zakarya Lasmar, Adam S. Sajna, Su-Yong Lee +1
We consider an evolution of two elementary quantum particles and ask the question: under what conditions such a system behaves as a single object? It is obvious that if the attract…
