Bose-Einstein condensation has in the last two decades been observed in cold atomic gases and in solid-state physics quasiparticles, exciton-polaritons and magnons, respectively. The perhaps most widely known example of a bosonic gas, photons in blackbody radiation, however exhibits no Bose-Einstein condensation, because the particle number is not conserved and at low temperatures the photons disappear in the system’s walls instead of massively occupying the cavity ground mode. This is not the… Expand
Bose-Einstein condensation of photons from the thermodynamic limit to small photon numbers
Abstract Photons can come to thermal equilibrium at room temperature by scattering multiple times from a fluorescent dye. By confining the light and dye in a microcavity, a minimum energy is set andExpand
Bose-Einstein condensation of photons in an ideal atomic gas
We study peculiarities of Bose-Einstein condensation of photons that are in thermodynamic equilibrium with atoms of noninteracting gases. General equations of the thermodynamic equilibrium of theExpand
Macroscopic quantum state analyzed particle by particle.
This report reports the first direct study of this kind of entanglement: discrete quantum tomography is used to reconstruct the joint quantum state of photon pairs extracted from polarization-squeezed light, confirming several predictions from spin-Squeezing theory. Expand
Number Fluctuations and Phase Diffusion in a Bose-Einstein Condensate of Light
We study phase diffusion in a Bose-Einstein condensate of light in a dye-filled optical microcavity, i.e., the spreading of the probability distribution for the condensate phase. To observe thisExpand
Kinetic theory of weakly ionized dilute gas of hydrogen-like atoms of the first principles of quantum statistics and dispersion laws of eigenwaves
We develop a microscopic approach to the construction of the kinetic theory of dilute weakly ionized gas of hydrogen-like atoms. The approach is based on the statements of the second quantizationExpand
New Developments in Laser Spectroscopy
During the last few years several new ideas have been born and new spectroscopic techniques have been developed that not only improve the spectral resolution and increase the sensitivity forExpand
On the theory of spatially inhomogeneous Bose-Einstein condensation of magnons in yttrium iron garnet
The Bose-Einstein condensation (BEC) of magnons created by a strong pumping in ferromagnetic thin films of yttrium iron garnet used as systems of finite size is considered analytically. Such aExpand
Localization of states, Bloch wave and quantum phase transitions in SUSY deformed potentials in non-Hermitian optical systems
For the first time, we have observed the annihilation of multiple eigenstates of the parent potentials and redistribution of the energy in the deformed potentials in the system with spontaneouslyExpand

A microscopic approach for the construction of the kinetic theory of low-temperature hydrogen-like gases in an external electromagnetic field was developed. The approach is based on the formulationExpand
Variable potentials for thermalized light and coupled condensates
Variable micropotentials for light are created by thermo-optic imprinting of a dye–polymer solution within a microcavity. A thermalized photon Bose–Einstein condensate as well as the coupling andExpand
