New BCH-like relations of the su(1, 1), su(2) and so(2, 1) Lie algebras
D. M. Tibaduiza, A. H. Aragão, C. Farina +1
In this work we demonstrate new BCH-like relations involving the generators of the su(1, 1), su(2) and so(2, 1) Lie algebras. We use our results to obtain in a straightforward way…
Unitary expansion of the time evolution operator
N. Zagury, A. Aragao, J. Casanova +1
We propose an expansion of the unitary evolution operator, associated to a given Schrödinger equation, in terms of a finite product of explicit unitary operators. In this manner, t…
Environment-induced entanglement with a single photon
Malena Hor-Meyll, Adriana Auyuanet, Carolina Borges +4
We propose an all-optical setup, which couples different degrees of freedom of a single photon, to investigate entanglement generation by a common environment. The two qubits are r…
A Factorization Law for Entanglement Decay
Thomas Konrad, Fernando de Melo, Markus Tiersch +3
We present a simple and general factorization law for quantum systems shared by two parties, which describes the time evolution of entanglement upon passage of either component thr…
Non-Relativistic Propagators via Schwinger's Method
A. Aragao, H. Boschi-Filho, C. Farina +1
In order to popularize the so called Schwinger's method we reconsider the Feynman propagator of two non-relativistic systems: a charged particle in a uniform magnetic field and a c…
