How Shannon Entropy Bridges Classical and Quantum Physics

Researchers resolved the apparent paradox between quantum mechanics and classical thermodynamics by demonstrating that while von Neumann entropy remains constant in quantum systems, Shannon entropy increases over time just as classical entropy does, thereby reconciling quantum theory with the second law of thermodynamics.

Conducting While Frozen: Graphene’s Quantum Paradox

A groundbreaking discovery in quantum physics has revealed a novel electronic state in twisted graphene layers, where electrons exhibit the paradoxical behavior of being simultaneously frozen yet capable of conducting current along edges without resistance.

Electron Spin Control Through Chiral Molecules

Recent research at Johannes Gutenberg University Mainz has demonstrated that chiral molecules placed on gold surfaces can effectively control electron spin direction based on their handedness (left or right), offering a promising alternative to traditional magnetic methods for developing more efficient electronic devices.
