Increasing and decreasing entanglement characteristics for continuous variables by a local photon subtraction

SY Lee, SW Ji, CW Lee - Physical Review A—Atomic, Molecular, and Optical …, 2013 - APS
We investigate how the entanglement characteristics of a non-Gaussian entangled state are
increased or decreased by a local photon subtraction operation. The non-Gaussian …

How bosonic is a pair of fermions?

MC Tichy, PA Bouvrie, K Mølmer - Applied Physics B, 2014 - Springer
Composite particles made of two fermions can be treated as ideal elementary bosons as
long as the constituent fermions are sufficiently entangled. In that case, the Pauli principle …

Low-temperature thermostatistics of Tamm–Dancoff deformed boson oscillators

Assembly of entangled fermions into multipartite composite bosons

Z Lasmar, PA Bouvrie, AS Sajna, MC Tichy… - Physical Review A, 2019 - APS
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 …

Quantum information approach to Bose–Einstein condensation of composite bosons

MC Tichy, PA Bouvrie, K Mølmer - Physical Review A—Atomic, Molecular, and …, 2013 - APS
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 of the …
