A novel approach to analyze pion femtoscopy for particle emitting sources with Bose–Einstein condensation

Results in Physics, 2022
Quantum correlations at higher-order were measured in lead–lead collisions at the world largest collider, and a substantial suppression was reported while measuring the three and four pions interferences.

Composite nature of hadrons and Bose-Einstein correlations

EPJ Web of Conferences, 2016
I am reporting results of two papers, written together with W.Florkowski and K.Zalewski [1, 2], discussing the consequences of the observation [3] that, due to their composite nature and thus finite size, hadrons observed in the HBT measurements must be ...

Bose-Einstein correlations in hadron-pairs from lepto-production on nuclei ranging from hydrogen to xenon [PDF]

, 2015
Bose-Einstein correlations of like-sign charged hadrons produced in deep-inelastic electron and positron scattering are studied in the HERMES experiment using nuclear targets of $^1$H, $^2$H, $^3$He, $^4$He, N, Ne, Kr, and Xe. A Gaussian approach is used

Harnessing center-of-mass excitations in quantum metrology

Physical Review Research, 2022
In quantum metrology, one typically creates correlations among atoms or photons to enhance measurement precision. Here, we show how one can use other excitations to perform quantum-enhanced measurements on the example of center-of-mass excitations of a ...

Bell correlations between spatially separated pairs of atoms

Nature Communications, 2019
Entangled particles some distance apart can be used to show the strikingly nonlocal nature of quantum mechanics. Here the authors generate spatially separated pairs of helium atoms by colliding Bose-Einstein condensates and show that they are entangled ...

New Bose-Einstein Results from L3 [PDF]

, 2001
In hadronic Z decays, we compare Bose-Einstein correlations in \Pgpz pairs with those in identical charged pion pairs. We also measure Bose-Einstein correlations in triplets of identical charged pions.

Reweighting Scheme for the Calculation of Grand‐Canonical Expectation Values in Quantum Monte Carlo Simulations With a Fermion Sign Problem

Contributions to Plasma Physics, EarlyView.
ABSTRACT Ab initio path integral Monte Carlo (PIMC) simulations constitute the gold standard for the estimation of a broad range of equilibrium properties of a host of interacting quantum many‐body systems spanning a broad range of conditions from ultracold atoms to warm dense quantum plasmas.

Observation of dynamic atom-atom correlation in liquid helium in real space

Nature Communications, 2017
Liquid helium can be treated as an ideal gas or a condensed liquid and displays intriguing features like Bose–Einstein condensation. Here the authors show that roton excitation reveals information on real space dynamic atom-atom correlations in ...
