A cost-efficient variant of the incremental Newton iteration for the matrix th root
Fuminori Tatsuoka, Tomohiro Sogabe, Yuto Miyatake +1
Incremental Newton (IN) iteration, proposed by Iannazzo, is stable for computing the matrix th root, and its computational cost is flops per iteration. In th…
Weyl points and topological nodal superfluids in a face-centered cubic optical lattice
Li-Jun Lang, Shao-Liang Zhang, K. T. Law +1
We point out that a face-centered cubic (FCC) optical lattice, which can be realised by a simple scheme using three lasers, provides one a highly controllable platform for creating…
Energy-preserving -Galerkin schemes for the Hunter--Saxton equation
Yuto Miyatake, Geonsik Eom, Tomohiro Sogabe +1
We consider the numerical integration of the Hunter--Saxton equation, which models the propagation of weakly nonlinear orientation waves. For the equation, we present two weak form…
Nodal Brillouin Zone Boundary from Folding a Chern Insulator
Li-Jun Lang, Shao-Liang Zhang, Qi Zhou
Chern insulator is a building block of many topological quantum matters, ranging from quantum spin Hall insulators to fractional Chern insulators. Here, we discuss a new type of in…
Contact matrix in dilute quantum systems
Shao-Liang Zhang, Mingyuan He, Qi Zhou
Contact has been well established as an important quantity to govern dilute quantum systems, in which the pairwise correlation at short distance traces a broad range of thermodynam…
A two-leg Su-Schrieffer-Heeger chain with glide reflection symmetry
Shao-Liang Zhang, Qi Zhou
The Su-Schrieffer-Heeger (SSH) model lays the foundation of many important concepts in quantum topological matters. Since it tells one that topological states may be distinguished…
