Intrinsic Asymmetry Within Quantum Systems Breaks Fundamental Particle Physics Rules

Di Xiao and colleagues at Huazhong University of Science and Technology, in collaboration with the University of Hamburg and Wuhan Institute of Quantum Technology, have identified sublattice kinks in bipartite fermionic lattices as intrinsically exhibiting charge-conjugation violation, a key concept in particle physics. The violation arises from the graph topology of the system's Hamiltonian, without requiring external symmetry breaking, and results in a measurable population asymmetry between different configurations. This asymmetry leads to an imbalanced production of sublattice kinks during dynamic processes, suggesting a potential pathway…
