Unsupervised Thermodynamics of Molecular Diffusion Models: Action-Operator Semantics and Auditable Free-Energy Readout
Wenjie Xi
Diffusion models are increasingly utilized for modeling molecular structures and conformational ensembles, yet the thermodynamic meaning of their learned representations and scores…
Autonomous Emergence of Hamiltonian in Deep Generative Models
Wenjie Xi, Wei-Qiang Chen
The unprecedented predictive success of deep generative models in complex many-body systems, such as AlphaFold 3, raises an epistemological question: do these networks merely memor…
On a class of fusion 2-category symmetry: condensation completion of braided fusion category
Wenjie Xi, Tian Lan, Longye Wang +2
Recently, many studies are focused on generalized global symmetry, a mixture of both invertible and non-invertible symmetries in various space-time dimensions. The complete structu…
A lattice realization of general three-dimensional topological order
Wenjie Xi, Ya-Lei Lu, Tian Lan +1
Topological orders are a class of phases of matter that beyond the Landau symmetry breaking paradigm. The two (spatial) dimensional (2d) topological orders have been thoroughly stu…
Fate of Quantum Anomalies for 1d lattice chiral fermion with a simple non-Hermitian Hamiltonian
Wei-Qiang Chen, Yong-Shi Wu, Wenjie Xi +2
It is generally believed that the 1+1D model for a single chiral fermion does not exist by itself alone on lattice. The obstruction to such a lattice realization is the failure to…
Classification of topological phases in one dimensional interacting non-Hermitian systems and emergent unitarity
Wenjie Xi, Zhi-Hao Zhang, Zheng-Cheng Gu +1
Topological phases in non-Hermitian systems have become fascinating subjects recently. In this paper, we attempt to classify topological phases in 1D interacting non-Hermitian syst…
Hunting Down Magnetic Monopoles in 2D Topological Insulators
Wenjie Xi, Wei Ku
Contrary to the electric charge that generates the electric field, magnetic charge (namely magnetic monopoles) does not exist in the elementary electromagnetism. Consequently, magn…
Non-necessity of band inversion process in 2D topological insulators for bulk gapless states and topological phase transitions
Wenjie Xi, Wei Ku
In commonly employed models for 2D topological insulators, bulk gapless states are well known to form at the band inversion points where the degeneracy of the states is protected b…
