Bose-Einstein Condensation of Pions in High Multiplicity Events [PDF]

open access: yes, 2006
We present microcanonical ensemble calculations of particle number fluctuations in the ideal pion gas approaching Bose-Einstein condensation. In the samples of events with a fixed number of all pions, $N_{\pi}$, one may observe a prominent signal.

High temperature Bose-Einstein condensation

open access: yesEPJ Web of Conferences, 2016
The indications of a possible pion condensation at the LHC are summarized. The condensation is predicted by the non-equilibrium hadronization model for 2.76 TeV Pb+Pb collisions at the LHC.

Bose-Einstein condensation of chromium. [PDF]

open access: yesPhysical Review Letters, 2005
We report on the generation of a Bose-Einstein condensate in a gas of chromium atoms, which have an exceptionally large magnetic dipole moment and therefore underlie anisotropic long-range interactions. The preparation of the chromium condensate requires

Spin waves in a Bose Ferromagnet

open access: yes, 2004
It is shown that the ferromagnetic transition takes place always above Bose-Einstein condensation in ferromagnetically coupled spinor Bose gases. We describe the Bose ferromagnet within Ginzburg-Landau theory by a "two-fluid" model below Bose-Einstein ...

Einstein–Bose condensation of Onsager vortices

open access: yesNew Journal of Physics, 2018
We have studied statistical mechanics of a gas of vortices in two dimensions. We introduce a new observable—a condensate fraction of Onsager vortices—to quantify the emergence of the vortex condensate.

Bose-Einstein condensation in complex networks. [PDF]

open access: yesPhysical Review Letters, 2000
The evolution of many complex systems, including the World Wide Web, business, and citation networks, is encoded in the dynamic web describing the interactions between the system's constituents.

Is a Trapped One-Dimensional Bose Gas a Luttinger Liquid?

open access: yes, 1997
The low-energy fluctuations of a trapped, interacting quasi one-dimensional Bose gas are studied. Our considerations apply to experiments with highly anisotropic traps.

Schrodinger equation for the one particle density matrix of thermal systems: An alternative formulation of Bose-Einstein condensation [PDF]

open access: yes, 2006
We formulate a linear Schrodinger equation with the temperature-dependent potential for the one-particle density matrix and obtain the condensation temperature of the Bose-Einstein condensate from a bound-state condition for the Schrodinger equation both

Bose–Einstein condensation of photons in an optical microcavity [PDF]

open access: yesNature, 2010
Bose–Einstein condensation (BEC)—the macroscopic ground-state accumulation of particles with integer spin (bosons) at low temperature and high density—has been observed in several physical systems, including cold atomic gases and solid-state ...

Complete Bose–Einstein Condensation in the Gross–Pitaevskii Regime [PDF]

open access: yes, 2017
We consider a gas of N bosons in a box with volume one interacting through a two-body potential with scattering length of order $${N^{-1}}$$N-1 (Gross–Pitaevskii limit).
