Thermodynamic Systems

7.4K
A thermodynamic system is a set of objects whose thermodynamic properties are of interest. The system is considered to be embedded in its surroundings or the environment. The system and its environment can exchange heat and do work on each other through a boundary that separates them. However, the immediate surroundings of the system interact with it directly and therefore have a much stronger influence on its behavior and properties.
Consider an example of  tea boiling in a kettle. The...

Statements of the Second Law of Thermodynamics

4.9K
The second law of thermodynamics can be stated in several different ways, and all of them can be shown to imply the others. The Clausius’ statement of the second law of thermodynamics is based on the irreversibility of spontaneous heat flow. It states that heat will not flow from the colder body to the hotter body unless some other process is involved. Additionally, as per the Kelvin’s statement, it is impossible to convert the heat from a single source into work without any other...

First Law of Thermodynamics

5.4K
A change in the internal energy of a system depends on the the net heat transfer into the system and the net work done by the system. The first law of thermodynamics, which is a generalized form of energy conservation, relates these three quantities mathematically. It states that the change in the internal energy equals the difference between the heat transfer and work done by the system.
The applied heat increases the internal energy of a system. Hence, conventionally heat is considered...

First Law of Thermodynamics

79.5K
The First Law of Thermodynamics states that energy cannot be created or destroyed, only transformed. This can be demonstrated within a classic food web where light energy from the sun is harnessed as radiant energy by plants, converted into chemical energy, and stored as complex carbohydrates. The vegetation is then consumed by animals and during the digestion process, the sugars release energy as heat. The sugars also produce chemical energy that either gets used up doing work, stored in...

Área de la Ciencia:

  • Física; Termodinámica Cuántica; Mecánica Estadística

Sus antecedentes:

  • La termodinámica a nanoescala es compleja debido a las fluctuaciones y los efectos cuánticos.; Los marcos termodinámicos existentes carecen de singularidad para los sistemas a nanoescala, ya que el calor y el trabajo dependen de los grados de libertad accesibles.

Objetivo del estudio:

  • Derivar un marco termodinámico novedoso aplicable a sistemas impulsados coherentemente.; Establecer una segunda ley de la termodinámica más estricta para estos sistemas.; Explorar las propiedades de ruido de los sistemas cuánticos impulsados-disipativos.

Principales métodos:

  • Derivación de un marco termodinámico asumiendo luz de salida accesible en sistemas impulsados coherentemente.; Aplicación e ilustración del marco en modelos físicos establecidos.; Análisis de las características de ruido de la luz de entrada y salida.

Principales resultados:

  • Se deriva una nueva segunda ley de la termodinámica, que es estrictamente más estricta que la convencional.; El marco dicta que la luz de salida de los sistemas impulsados debe exhibir un mayor ruido que la luz de entrada.; El máser de tres niveles se reinterpreta como un motor que reduce efectivamente el ruido de un impulso coherente.

Conclusiones:

  • El marco termodinámico desarrollado proporciona un enfoque único para sistemas impulsados coherentemente.; Este trabajo avanza en la comprensión de las propiedades de ruido en sistemas cuánticos impulsados-disipativos.; Los hallazgos abren nuevas vías de investigación en termodinámica a nanoescala y ciencia de la información cuántica.
