Topology shared between classical metamaterials and interacting superconductors
Po-Wei Lo, Chao-Ming Jian, Michael J Lawler
Supersymmetry has been studied at a linear level between normal modes of metamaterials described by rigidity matrices and non-interacting quantum Hamiltonians. The connection betwe…
The fate of topological frustration in quantum spin ladders and generalizations
Po-Wei Lo, Michael J. Lawler
Topological frustration (or topological mechanics) is the existence of classical zero modes that are robust to many but not all distortions of the Hamiltonian. It arises naturally…
Topology in non-linear mechanical systems
Po-Wei Lo, Krishanu Roychowdhury, Bryan Gin-ge Chen +3
Many advancements have been made in the field of topological mechanics. The majority of the works, however, concerns the topological invariant in a linear theory. We, in this work,…
Inducing Kondo Screening of Vacancy Magnetic Moments in Graphene with Gating and Local Curvature
Yuhang Jiang, Jinhai Mao, Po-Wei Lo +7
In normal metals, the magnetic-moment of impurity-spins disappears below a characteristic Kondo temperature, TK. This marks the formation of a polarized cloud of conduction band el…
Modeling of gate controlled Kondo effect at carbon point-defects in graphene
Daniel May, Po-Wei Lo, Kira Deltenre +7
We study the magnetic properties in the vicinity of a single carbon defect in a monolayer of graphene. We include the unbound orbital and the vacancy induced bound state in…
Quantum Critical Transition and Kondo Screening of Magnetic Moments in Graphene
Jinhai Mao, Yuhang Jiang, Po-Wei Lo +7
In normal metals, the magnetic moment of impurity spins disappears below a characteristic Kondo temperature, TK, where coupling with the conduction-band electrons produces an entan…
Gate-tunable Kondo resistivity and dephasing rate in graphene studied by numerical renormalization group calculations
Po-Wei Lo, Guang-Yu Guo, Frithjof B. Anders
We investigate the resistivity and dephasing rate in the Kondo regime due to magnetic impurities in graphene with different chemial potentials (). The Kondo effect due to either…
