Classification of Dipolar Symmetry-Protected Topological Phases: Matrix Product States, Stabilizer Hamiltonians and Finite Tensor Gauge Theories
Ho Tat Lam
We classify one-dimensional symmetry-protected topological (SPT) phases protected by dipole symmetries. A dipole symmetry comprises two sets of symmetry generators: charge and dipo…
Topological quantum chains protected by dipolar and other modulated symmetries
Jung Hoon Han, Ethan Lake, Ho Tat Lam +2
We investigate the physics of one-dimensional symmetry protected topological (SPT) phases protected by symmetries whose symmetry generators exhibit spatial modulation. We focus in…
Fractons on Graphs and Complexity
Pranay Gorantla, Ho Tat Lam, Shu-Heng Shao
We introduce two exotic lattice models on a general spatial graph. The first one is a matter theory of a compact Lifshitz scalar field, while the second one is a certain rank-2 $U(…
Optimization of Reliability of Network of Given Connectivity using Genetic Algorithm
Ho Tat Lam, Kwok Yip Szeto
Reliability is one of the important measures of how well the system meets its design objective, and mathematically is the probability that a system will perform satisfactorily for…
