Researchers offer a feed -controlled heat engine that exploits the thermal volatility with strategies on a microscope scale, which opens new avenues for energy harvesting in nanosic devices.

In this study, led by Dr. Edgar Rolden, from the Abdus Salam International Center for theoretical physics, challenged the thermodynamic understanding of the two centuries, which proposed a method to overtake a method, which was once considered an unacceptable limit in physics.

“I have always been attracted to car engine, or more sophisticated machines, such as solar cells, or natural, such as cells and organisms, such as cells and organisms,” Rolden told Fiz.com.

Strategic gambling

Standard heat engine, including well-established carnot engine, are more binding than carnot performance: η = 1- (t_c/t_h), Where t_c And t_h Identify the temperature of cold and hot thermal reservoirs, respectively.

This bound, which was founded by Saadi Karnot in 1824, has been considered absolute for two centuries. In order to exceed this limit in classical thermodiatics, other laws of thermodynamics will be required.

The gambling engine (GCE) has included gambling strategies derived from the game theory and has been implemented in thermodynamics. The system uses an external controller or “devil”, which is derived from Maxwell’s famous thinking experience, to implement strategic measures according to specific standards.

The term “gambling” was developed by some of us in the previous work, ‘Thermodumics of gambling monsters,’ prl In 2021, “Rolden explained.

“Gambling can be dragged, for example, in Black Jack, where the players depend on the cards in their hands, and also follow a particular standard.”

Innovation centers at the isothermal compression stage of the engine.

During this stage, the particle usually goes through compression as the trap hardness gradually increases, which requires a lot of work input.

However, the devil continues to monitor the particle position using high -speed laser interface during this compression period.

When the particle crosses the Trap Center (Position X = 0) before the default date, the system immediately jumps into the final compression state at a zero work cost.

Mechanics of microscope performance

The engine operates using colidal particle. Unlike piston and cylinders macroscope engines, this nanosical system adjusts the ability to produce thermodic cycle of thermodic cycle.

“The idea behind the GCE is to connect the key method of energy extraction in the heat engine (in the works that remove some parts of the heat from the hot bath, such as converting into a car engine) and the information machine (such as the devil of Maxwell to apply feedback at specific moments).”

The strategic benefit emerges from the exploitation of the brown movement, which revolves around the particle trap center.

The molecular collision in the surrounding water causes the thermal energy to usually fluctuate within a few hundred nanometers of the balance position.

Researchers have vowed that this gambling strategy creates the possibility of survival that falls rapidly over the time of the cycle, that is, as the operational time scales grow, the performance increases. In the Costatic range, the performance reaches 100 %.

New shape to performance in basic limits

Claims to overtake Carnote’s performance requires cautious interpretation within the thermodina principles. Rolden emphasized that his definition remains in accordance with the classical thermodynamics, while the information process shows new possibilities.

He explained, “We use the classic definition of performance, that is, the part of every cycle in each cycle is divided into every cycle, the two are on the average machine’s many runs.”

“We show that such a part can exceed the Cornect value in the GCE, and can reach one, which is converted to the amount of heat in converted into the task.”

This difference is calculated in the cost of information processing. Although thermal-to-mechanical conversion can exceed the classic limits, full energy budget-including information acquisition and processing-respects the basic thermodynamic obstacles when it is fully considered.

“If we look at the cost of eliminating information about the particle position in each cycle, we come up with an alternative definition of performance that respects the range of the cornatic.”

Toward the laboratory reality from theory

Researchers used realistic parameters from previous experimental studies.

“We believe that our ideological idea can be felt very quickly in the lab,” said Rolden. “All our numerical results were used using realistic experimental parameters, which was taken from our previous work, which felt the first carnot machine trapped in optical flames.”

Important experimental challenges include faster position detection and implementation of fast feedback. Research shows that the frequency of taking samples above 100kg is very important. Below this doorstep, the performance detection delays reduces the performance significantly, which prevents maximum time of zero cost interventions.

“Our ideas, and the concepts of the realistic design of the effective nanomotics that violate the classic thermoditatic boundaries in the emerging field of the strategic thermodynamics, are so proof of the concepts of affecting the realistic design of the classic thermoditic.”
