Geometrical approach and topological electron density in the superconductor
Karyn Le Hur, Kabir Narayanan, Óscar Mañas Chambert
We present an analysis on the geometrical and physical nature of the superconductor on the square lattice, with an emphasis on the topological phase transition at half…
Spin qubit gates via phonon buses in electron nanowires
Dylan Lewis, Roopayan Ghosh, Sanjeev Kumar +4
Scalable architectures for quantum computing using semiconductor quantum dots require interactions between qubits beyond adjacent quantum dots. Here, we propose using nanowires of…
Spin Response of a Magnetic Monopole and Quantum Hall Response in Topological Lattice Models through Local Invariants and Light
Karyn Le Hur, Andrea Baldanza
Here, we elaborate on and develop the geometrical approach introduced in K. Le Hur, Physics Reports 1104 1-42 (2025) between the magnetic monopole created from a radial field, quan…
Theory of local orbital magnetization: local Berry curvature
Sariah Al Saati, Karyn Le Hur, Frédéric Piéchon
We develop a thermodynamic theory of local orbital magnetization based on a perturbative expansion of the magnetic-field-dependent local density of states. Applicable to periodic c…
Free Majorana Fermions with Superconducting Quantum Wires and a Magnetic Impurity
Karyn Le Hur
Through the two-channel Kondo model, I address a magnetic spin-1/2 impurity interacting with a bound state of spin origin at the edge in a Luther-Emery liquid showing a spin gap in…
Topological Quantum Spin Hall Semimetals with Light
Karyn Le Hur
We introduce a quantum spin Hall semimetal or Fermi liquid characterized with a Z2 topological invariant, measurable through circularly polarized light. We propose its engineering…
