Nitrogen is a liquid under −195.8 °C (77.3 K).. In physics, cryogenics is the production and behaviour of materials at very low temperatures.. The 13th International Institute of Refrigeration's (IIR) International Congress of Refrigeration (held in Washington, DC in 1971) endorsed a universal definition of "cryogenics" and "cryogenic" by accepting a threshold of 120 K (−153 °C) to ...
Cryochemistry is the study of chemical interactions at temperatures below −150 °C (−238 °F; 123 K). [1] It is derived from the Greek word cryos, meaning 'cold'.It overlaps with many other sciences, including chemistry, cryobiology, condensed matter physics, and even astrochemistry.
Low Temperature Physics is a monthly peer-reviewed scientific journal covering all aspects of low temperature physics. The journal publishes original articles, review articles, brief communications, memoirs, and biographies. The editor-in-chief is Yurii G. Naidyuk.
chemistry (Proportion of "active" molecules or atoms) Arrhenius number = Svante Arrhenius: chemistry (ratio of activation energy to thermal energy) [1] Atomic weight: M: chemistry (mass of one atom divided by the atomic mass constant, 1 Da) Bodenstein number: Bo or Bd
Diagram of temperature (T) and pressure (p) showing the quantum critical point (QCP) and quantum phase transitions. Talking about quantum phase transitions means talking about transitions at T = 0: by tuning a non-temperature parameter like pressure, chemical composition or magnetic field, one could suppress e.g. some transition temperature like the Curie or Néel temperature to 0 K.
The following is a timeline of low-temperature technology and cryogenic technology (refrigeration down to close to absolute zero, i.e. –273.15 °C, −459.67 °F or 0 K). [1] It also lists important milestones in thermometry , thermodynamics , statistical physics and calorimetry , that were crucial in development of low temperature systems.
The temperature below which such gaps form is known as the Peierls transition temperature, T P. The electron spins are spatially modulated to form a standing spin wave in a spin density wave (SDW). A SDW can be viewed as two CDWs for the spin-up and spin-down subbands, whose charge modulations are 180° out-of-phase.
[1] [2] The LT conferences are endorsed by the International Union of Pure and Applied Physics (IUPAP) via its Commission on Low Temperature Physics (C5). The mandate of the LT conferences is to promote the exchange of information and views among the members of the international scientific community in the general field of Low Temperature Physics.
