（ 80th Anniversary Conference Series of the School of Physical Science and Technology） 

Lanzhou University, July 12th to 16th, 2026

Quantum/wave chaos focuses on the quantum/wave manifestations of classically chaotic systems. Many spectacular phenomena are unveiled ranging from universal statistics based on random matrix approaches to non-universalities described by semi-classical theories in closed, scattering and driven systems. From the experimental side, various wave-chaotic platforms, like electro-magnetic wave, liquid surface wave and mechanical wave systems, are employed to validate and discover new theories and phenomena in quantum chaos due to the similarities in the governing equations for all types of waves. This conference will focus on the latest developments and international cutting-edge trends in quantum chaos and wave chaos, and showcase the latest theoretical advances and experimental results.

1. Workshop Themes:

This conference will focus on the latest developments and international frontier directions in quantum chaos, and will serve as a platform to exchange recent advances and discuss key challenges in both quantum chaos and wave chaos. The main topics of this meeting are as follows:

Ø 1. Recent advances in the theory, methods, and experiments of (many-body) quantum chaos

Ø 2. Realization and observation of wave chaos phenomena across different experimental platforms

Ø 3. Non-Euclidean geometry, nonlinearity, and non-Hermitian effects in wave-chaotic systems

Ø 4. Control, optimization, and application prospects of complex wave systems

Ø 5. Other related topics.

2. Workshop Date:

The workshop will be held at Lanzhou University from July 12 to 16, 2026.

Registration will take place on Sunday, July 12.

The scientific program will run from July 13 to 15.

3. Workshop Venue:

The meeting will be held in Room 1226, the Science and Technology Building, Lanzhou University, Gansu 730000, China.

4. Hotel:

Great Wall Jianguo Hotel and Tsuiying Hotel.

5. Local organizer:

Hong-Ya Xu, Cheng-Zhen Wang, Ya-Lei Song, Zhen-Qi Chen, and Liang Huang
