Gaplessness indicator by topologically trivial twisting operators
Yuan Yao, Linhao Li, Feng-Feng Song
We propose several general necessary conditions for quantum many-body system in one dimension respecting U(1) symmetry to be gapped. We show that the ground-state expectation value…
Magnetization Plateau and Spin Supersolidity in YCu(OD)Br under Magnetic Fields up to 120~T
Hiroaki Hayashi, Han Li, Feng-Feng Song +11
We performed high-precision magnetization measurements up to 120~T on three compositions of the newly discovered kagome antiferromagnet YCu(OD)Br (YCOB), reveal…
Variational boundary based tensor network renormalization group
Feng-Feng Song, Naoki Kawashima
We propose a real-space renormalization group algorithm for accurately coarse-graining two-dimensional tensor networks. The central innovation of our method lies in utilizing varia…
Correlated reaction coordinate motion produces non-additive rate enhancement for electron and energy transfer in multi-acceptor structures
Hanggai Nuomin, Feng-Feng Song, Peng Zhang +1
Molecular structures with multiple donor, bridge, or acceptor units can display quantum interference effects that influence electron and energy transfer (ET and EnT) rates. Recent…
Superfluid dome in the spatially modulated two-dimensional XY model
Feng-Feng Song, Aditya Chugh, Hanggai Nuomin +2
In strongly correlated electron systems, superconductivity and charge density waves often coexist in close proximity, suggesting a deeper relationship between these competing phase…
Emergent Intermediate Phase in the - XY model from Tensor Network Approaches
Feng-Feng Song, Hanggai Nuomin, Naoki Kawashima
We investigate the finite-temperature phase diagram of the classical - XY model on a square lattice using a tensor network approach designed for frustrated spin systems.…
