The Macroscopic Description of Chaotic Quantum Systems

The world of quantum physics is known for its complexity and chaos, but can these systems be described using simple theories? A recent study led by Professor Monika Aidelsburger and Professor Immanuel Bloch from the LMU Faculty of Physics suggests that quantum many-body systems may indeed be able to be described macroscopically through simple diffusion equations with random noise. This groundbreaking research opens up new possibilities for understanding the behavior of chaotic quantum systems.

The study introduces the concept of fluctuating hydrodynamics (FHD), which suggests that the behavior of a system can be determined by a single quantity – the diffusion constant. This theory simplifies the macroscopic description of systems, eliminating the need to delve into the microscopic interactions of particles. The random collisions of particles with water molecules in Brownian motion are described as white noise, leading to a macroscopic understanding of system behavior.

Quantum systems present unique challenges due to the fundamental differences in the laws of physics governing classical and quantum particles. Concepts like uncertainty and entanglement make quantum systems difficult to predict and analyze. However, the application of FHD to chaotic quantum systems presents an opportunity to simplify the understanding of these complex systems.

The research team conducted experiments on chaotic many-body quantum systems using ultracold cesium atoms in optical lattices. By observing the dynamics of the system over time, the team was able to measure fluctuations and density correlations. The results indicated that FHD could be used to describe the system both qualitatively and quantitatively, providing valuable insights into the behavior of chaotic quantum systems.

The findings of the study suggest that chaotic quantum systems, despite their microscopic complexity, can be described as macroscopic diffusion processes. This discovery has significant implications for the field of quantum physics, as it opens up new avenues for understanding and analyzing the behavior of these intricate systems. By applying FHD to chaotic quantum systems, researchers may be able to gain a better understanding of their underlying dynamics.

The study led by Professor Aidelsburger and Professor Bloch sheds light on the potential for describing chaotic quantum systems using macroscopic diffusion equations with random noise. This research paves the way for future studies in the field of quantum physics, providing a new perspective on the behavior of complex quantum systems. By simplifying the description of chaotic quantum systems, researchers may be able to unlock new insights and discoveries in this fascinating realm of physics.
