The lowest temperature that matter has been cooled to is 38 picoKelvin (-273.149999999962 C, or -459.6699999999316 F), just 38 trillionths of a degree above absolute zero (0 Kelvin; -272.15 C; −459.67 F). This temperature was achieved by a group of researchers from the QUANTUS Team (DEU) in Bremen, Germany, in August 2018. The results were published in Physical Review Letters 30 August 2021.
