Heat engines convert heat into work—for example, moving a piston in a certain direction. For an engine to be 100% efficient, when the process is reversed—the piston returns to its original state—there ...

The engine works by taking heat from the hot reservoir, converting some of it into useful work, and rejecting the remaining heat to the cold reservoir. The thermodynamic cycle followed by the engine ...

According to holography, a black hole is dual to a thermal state in a strongly coupled quantum system. One of the best-known examples of holography is the Anti-de Sitter/Conformal Field Theory ...

Heat engines near the adiabatic limit typically assume a working medium at thermal equilibrium. However, quantum many-body systems often showcase conservation laws that hinder thermalization, leading ...

As the world battles rising inflation, a cost-of-living crisis, climate change and more, it’s clear that the fossil-fueled status quo is not working. Fossil fuels may have seemed like the crutch we ...
