The International Conference on Low Temperature Physics (LT) is an academic conference held every three years near the month of September attracting on average well over a thousand participants from all over the world.[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.
Usually, several other satellite meetings are also held just before or after the LT conferences in neighboring cities such as the International Conference on Ultra Low Temperature Physics series (ULT) as well as other meetings related to the topics listed below. Starting from 1998, the Symposium on Quantum Fluids and Solids (QFT) conference series was decided to be held in all non-LT years.[3]
The general field of low temperature physics is broad, but usually the LT conferences are divided into five parallel programs:
The conferences are typically held in the following pattern: Europe > Asia > The Americas > Europe. The LT29 Conference was originally planned to be held in 2020, but was postponed two years due to COVID-19.[4]

The Fritz London Memorial Prize was created to recognize scientists who made outstanding contributions to the advances of the field of Low Temperature Physics. It is traditionally awarded in the opening session of the LT meeting.[17] The prize is named in honor of Fritz London.[18] [19]
Other prizes awarded in the LT meeting are the Simon Memorial Prize[20] and the IUPAP Young Scientist Prizes in Low Temperature Physics (since LT-25).
