Summary
Scientists derived a heat exchange fluctuation relation for open quantum systems. This quantum fluctuation relation shows that heat absorption/release probabilities depend on heat amount and temperature differences, akin to classical thermodynamics.
Area of Science:
- Quantum Thermodynamics
- Statistical Mechanics
- Open Quantum Systems
Background:
- Understanding heat exchange in open quantum systems is crucial for quantum thermodynamics.
- Markovian dynamics describe systems interacting with their environment.
Purpose of the Study:
- To derive and analyze a fluctuation relation for heat exchange in open quantum systems.
- To investigate the relationship between heat transfer probabilities and thermodynamic quantities.
Main Methods:
- Derivation of a fluctuation relation for heat exchange.
- Analysis of thermalizing Markovian dynamics.
- Probabilistic analysis of heat absorption and release.
Main Results:
- A fluctuation relation for heat exchange in open quantum systems was derived.
- The ratio of heat absorption to release probabilities is an exponential function of heat and temperature differences.
- The probability of violating the second law of thermodynamics decreases exponentially with heat and temperature differences.
Conclusions:
- The derived fluctuation relation is analogous to classical fluctuation relations.
- This work provides insights into the quantum nature of thermodynamic laws.
- The findings have implications for understanding non-equilibrium thermodynamics in quantum regimes.

It is said that the energy of an electron in an atom is quantized; that is, it can be equal only to certain specific values and can jump from one energy level to another but not transition smoothly or stay between these levels.

Gas exchange, the intake of molecular oxygen (O2) from the environment and the outflow of carbon dioxide (CO2) into the environment, is necessary for cellular function. Gas exchange during respiration occurs largely via the movement of gas molecules along pressure gradients. Gas travels from areas of higher partial pressure to areas of lower partial pressure. In mammals, gas exchange occurs in the alveoli of the lungs, which are adjacent to capillaries and share a membrane with them.

Shortly after de Broglie published his ideas that the electron in a hydrogen atom could be better thought of as being a circular standing wave instead of a particle moving in quantized circular orbits, Erwin Schrödinger extended de Broglie’s work by deriving what is now known as the Schrödinger equation. When Schrödinger applied his equation to hydrogen-like atoms, he was able to reproduce Bohr’s expression for the energy and, thus, the Rydberg formula governing hydrogen spectra.

We have discussed why we form relationships, what attracts us to others, and different types of love. But what determines whether we are satisfied with and stay in a relationship? One theory that provides an explanation is social exchange theory. According to social exchange theory, we act as naïve economists in keeping a tally of the ratio of costs and benefits of forming and maintaining a relationship with others (Rusbult & Van Lange, 2003).

The specific heat capacity of a substance refers to the energy required to increase the temperature of one gram of that substance by one degree Celcius. Specific heat capacity is often represented in calories (cal), grams (g), and degrees Celsius (oC), but can also be expressed in joules (J), kilograms (kg), and Kelvin (K), among other units.
For example, increasing the temperature of one gram of water by 1°C requires one calorie of heat energy and can be written as 1 cal/g-°C, or...

Thermal Energy Microscopically, thermal energy is the kinetic energy associated with the random motion of atoms and molecules. Temperature is a quantitative measure of “hot” or “cold”, which depends on the amount of thermal energy. When the atoms and molecules in an object are moving or vibrating quickly, they have a higher average kinetic energy (KE) (or higher thermal energy), and the object is perceived as “hot”, or it is described as being at a higher temperature. When the...
