Quantum heat engines and refrigerators (original) (raw)
A quantum heat engine is a device that generates power from the heat flow between hot and cold reservoirs. The operation mechanism of the engine can be described by the laws of quantum mechanics.

When the power is supplied by a laser the process is termed optical pumping or laser cooling, suggested by Wineland and Hänsch.Surprisingly heat engines and refrigerators can operate up to the scale of a single particle thus justifying the need for a quantum theory termed quantum thermodynamics. (en) Um mecanismo de calor quântico é um dispositivo que gera energia a partir do fluxo de calor entre os reservatórios quentes e frios. O mecanismo de operação do mecanismo pode ser descrito pelas leis da mecânica quântica. A primeira realização de um motor de aquecimento quântico foi apontada por Scovil e Schulz-DuBois em 1959, mostrando a conexão da eficiência do mecanismo Carnot e do maser de três níveis. Os refrigeradores quânticos compartilham a estrutura dos motores quânticos de calor com o objetivo de bombear calor de um banho frio para um quente consumindo energia sugerida pela primeira vez por Geusic, Schulz-DuBois, De Grasse e Scovil. Quando a energia é fornecida por um laser, o processo é denominado ou resfriamento a laser, sugerido por Weinland e Hench. Motores térmicos e refrigeradores podem operar até a escala de uma única partícula, justificando a necessidade de uma teoria quântica denominada termodinâmica quântica. (pt) |
