Eigenstate thermalization hypothesis and approximate quantum error correction [PDF]
Journal of High Energy Physics, 2019 Abstract The eigenstate thermalization hypothesis (ETH) is a powerful conjecture for understanding how statistical mechanics emerges in a large class of many-body quantum systems. It has also been interpreted in a CFT context, and, in particular, holographic CFTs are expected to satisfy ETH.

ERRORS IN THERMAL IMAGERS TEMPERATURE RESOLUTION DETERMINING
Вестник Киевского политехнического института. Серия приборостроение, 2022 Thermal imaging methods of environmental observation are often accompanied by the need to quantify the temperature distribution on the object’s surfaces. In such cases, the accuracy of modeling the information conversion processes that occur in thermal imaging systems is essential.

Thermally induced error: Density limit for magnetic data storage [PDF]
Applied Physics Letters, 2012 Magnetic data storage is pervasive in the preservation of digital information, and the rapid pace of computer development requires ever more capacity. Increasing the storage density for magnetic hard disk drives requires a reduced bit size, previously thought to be limited by the thermal stability of the constituent magnetic grains.
