Quantum freezing phenomena persist for Rènyi discord in dimer systems. This study explores how various parameters influence these quantum correlation behaviors under non-Markovian conditions.
Area of Science:
- Quantum Information Science
- Condensed Matter Physics
- Quantum Optics
Background:
- Quantum correlation is a fundamental resource in quantum information processing.
- The freezing phenomenon, a characteristic of quantum correlation, has been previously studied using geometric and quantum discord methods.
- Understanding quantum correlations in complex systems is crucial for developing quantum technologies.
Purpose of the Study:
- To investigate the properties of Rènyi discord in a specific quantum system.
- To determine if the freezing phenomenon exists for Rènyi discord under non-Markovian conditions.
- To analyze the influence of different system parameters on the freezing behaviors of Rènyi discord.
Main Methods:
- Utilizing Rènyi discord as a quantifier of quantum correlation.
- Modeling two independent Dimer Systems coupled to two correlated Fermi-spin environments.
- Analyzing the system dynamics under non-Markovian conditions.
Main Results:

Freezing Point Depression and Boiling Point Elevation
The boiling point of a liquid is the temperature at which its vapor pressure is equal to ambient atmospheric pressure. Since the vapor pressure of a solution is lowered due to the presence of nonvolatile solutes, it stands to reason that the solution’s boiling point will subsequently be increased. Vapor pressure increases with temperature, and so a solution will require a higher temperature than will pure solvent to achieve any given vapor pressure, including one...
