III. Research Themes:
Entanglement structure in interacting topological and disordered systems
Many interesting physics problems in strongly correlated systems are difficult to solve, and require non-perturbative methods as AdS/CFT duality or Matrix/Tensor product states to tackle. Quantum entanglement has recently been regarded as a bridge between these seemingly different viewpoints, and it may hold the key to understand some exotic phases in these systems.
We propose to study these subjects:
• Wavelet transformation and topological order.
• Entanglement structures in disordered system with strong interaction.
• Entanglement structures in many-body localization.
Topology and entanglement in non-equilibrium systems
Non-equilibrium many-body quantum systems are challenging and interesting. To further develop the concept of non-equilibrium phases of matter, new theoretical
and numerical tools are required. We aim to develop necessary tools that can be used to investigate the topology and entanglement in non-equilibrium systems.
We propose to study these subjects:
• Topology and entanglement in quench and driven dynamics.
• Entanglement in non-equilibrium CFT.
• Integrable methods on non-equilibrium phases.
Machine learning and Physics
In the past years, significant progresses have been made in machine learning algorithms that have been used in the classification and interpretation of large data sets, sparking a revolution in areas such as image and natural language processing.
Recently, it has been understood that the fundamental concepts behind the success of machine learning is closely related to the renormalization group in statistical physics. This raises the important question of what further insights remain to be found at the intersection of machine learning and fields such as statistical physics, condensed matter, and quantum information.
We propose to explore these research directions:
• Use techniques from machine learning to tackle quantum many-body problems.
• Explore the possible connections between deep learning, the renormalization group, and tensor networks/MERA.
• Application of reinforcement learning in quantum control and error corrections.
