Fermionic versus bosonic behavior of confined Wigner molecules
Eloisa Cuestas, P. Alexander Bouvrie, Ana P. Majtey
We assess whether a confined Wigner molecule constituted by fermions behaves as bosons or fermions. Following the work by C. K. Law [Phys. Rev. A \textbf{71}, 034306…
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…
Entanglement between two spatially separated ultracold interacting Fermi gases
P. Alexander Bouvrie, Eloisa Cuestas, Itzhak Roditi +1
Multiparticle entangled states, essential ingredients for modern quantum technologies, are routinely generated in experiments of atomic Bose-Einstein condensates (BECs). However, t…
Composite-boson approach to molecular Bose-Einstein condensates in mixtures of ultracold Fermi gases
P. Alexander Bouvrie, Malte C. Tichy, Itzhak Roditi
We show that an ansatz based on independent composite bosons [Phys. Rep. 463, 215 (2008)] accurately describes the condensate fraction of molecular Bose-Einstein condensates in ult…
Entanglement generation through particle detection in systems of identical fermions
P. A. Bouvrie, A. Valdés-Hernández, A. P. Majtey +2
We investigate the generation of entanglement in systems of identical fermions through a process involving particle detection, focusing on the implications that this kind of proces…
Multipartite concurrence for identical-fermion systems
A. P. Majtey, P. A. Bouvrie, A. Valdés-Hernández +1
We study the problem of detecting multipartite entanglement among indistinguishable fermionic particles. A multipartite concurrence for pure states of identical fermions, each…
Quantifying Dirac hydrogenic effects via complexity measures
P. A. Bouvrie, S. López-Rosa, J. S. Dehesa
The primary dynamical Dirac relativistic effects can only be seen in hydrogenic systems without the complications introduced by electron-electron interactions in many-electron syst…
Entanglement and the Born-Oppenheimer approximation in an exactly solvable quantum many-body system
P. A. Bouvrie, A. P. Majtey, M. C. Tichy +2
We investigate the correlations between different bipartitions of an exactly solvable one-dimensional many-body Moshinsky model consisting of Nn "nuclei" and Ne "electrons". We stu…
Two-boson composites
Malte C. Tichy, Peter Alexander Bouvrie, Klaus Mølmer
Composite bosons made of two bosonic constituents exhibit deviations from ideal bosonic behavior due to their substructure. This deviation is reflected by the normalization ratio o…
Collective interference of composite two-fermion bosons
Malte C. Tichy, Peter Alexander Bouvrie, Klaus Mølmer
The composite character of two-fermion bosons manifests itself in the interference of many composites as a deviation from the ideal bosonic behavior. A state of many composite boso…
Bosonic behavior of entangled fermions
Malte C. Tichy, Peter Alexander Bouvrie, Klaus Mølmer
Two bound, entangled fermions form a composite boson, which can be treated as an elementary boson as long as the Pauli principle does not affect the behavior of many such composite…
Quantum entanglement in exactly soluble atomic models: The Moshinsky model with three electrons, and with two electrons in a uniform magnetic field
P. A. Bouvrie, A. P. Majtey, A. R. Plastino +2
We investigate the entanglement-related features of the eigenstates of two exactly soluble atomic models: a one-dimensional three-electron Moshinsky model, and a three-dimensional…
