Bose-Einstein Condensation in Alkali Gases 1. Bose-Einstein Condensation At the beginning of the twentieth century, the quantum nature of thermal electromagnetic radiation was a subject of intense interest. This was sparked by Max . superfluidity could be a manifestation of bosonic condensation of the helium atoms. This

The early experiments on Bose–Einstein condensation in dilute atomic gases accomplished three long-standing goals. First, cooling of neutral atoms into their motional ground state, thus subjecting them to . as a result of superfluidity when the refrigerant is a BEC 29, or simply by heating30. The.

Liquid 4He undergoes Bose-Einstein condensation to enter a superfluid state without viscosity when it is cooled below a critical temperature of 2.176K. In 1995, similar superfluidity behavior was also realized by the Bose-Einstein condensation of alkali atoms in gaseous phase [1,2]. An interesting question comes out: “Does

Key words: Bose-Einstein condensation; degenerate atomic gases; mechanical stabil-ity; superconductivity; superfluidity. Accepted: May 15, 1996 1. Introduction One of the most important objectives of atomic physics in the last two decades, has been the achieve-ment of Bose-Einstein condensation in a weakly inter-acting gas.

An infrared converter, LinTronic TT455-RT-238 (with BOSE feature enabled) or TT455-RT-003 (dedicated BOSE controller), receives the infrared signals from the BEO4, converts them into an appropriate BOSE infrared signal, and sends it to the BOSE system. It is assumed that the user owns: - a BOSE LIFESTYLE 18/28 SERIES II system.

empties. Instead of Bose condensing into the ground state of the cavity, the photons are absorbed by the walls which increases the total entropy. However, if a photon gas were to thermalize with the number of photons being conserved (e.g. by Compton scattering with a thermal electron gas) it could, in principle, form a Bose condensate of photons.

In both cases Bose-Einstein Condensation is the key phenomenon. The simplest model of BEC is best illustrated basing on 4He effects at the low temperature region. SUPERFLUIDITY To start a deliberation on the superfluidity it is necessary to move into the certain range of values of the basic thermodynamic quantities – the temperature T and .

[1] and the achievment of Bose-Einstein Condensation [2, 3, 4], can now be used as standard tools in a new era, making it possible to advance problems that can provide useful information for the understanding of closely related systems from other fields of physics such as solid state physics or material sciences.

Condensation on windows can sometimes be an indicator of excessive relative humidity. Look for water and ice on windows. Check for damp spots on the ceiling, particularly in closets.Water-filled blisters on outside paint surfaces can also indicate excessive indoor humidity. 3 What is condensation?Moisture on the windows is a form of condensation.

state, but condensation and superfluidity are intrinsically linked, how can electrons ever become superconducting? The solution seems obvious: fermions might team up in bosonic pairs with integer spin that can undergo Bose-Einstein condensation. After all, one can think of 4He as a composite boson, formed by a fermionic He -Ion and an electron.

Classical physics analogy: let’s fill a container with a non-ideal gas and start lowering the temperature. The gas density remains constant until the condensation of gas (vapor) occurs. Since the density of liquid is much higher than that of gas, the gas density decreases with T.
