Lorentz force on superconducting vortices near line defects Open
In type-II superconductors, magnetic flux penetrates in the form of quantized vortices whose dissipative motion, driven by the Lorentz force, can degrade superconductivity. Understanding vortex dynamics in both homogeneous regions and near…

Bias-preserving and error-detectable entangling operations in a superconducting dual-rail system Open
For useful quantum computation, error-corrected machines are required that can dramatically reduce the inevitable errors experienced by physical qubits. While significant progress has been made in approaching and exceeding the surface-code…

Scanning SQUID study of ferromagnetism and superconductivity in infinite-layer nickelates Open
Infinite-layer nickelates $R_{1-x}$Sr$_{x}$NiO$_{2}$ ($R$ = La, Pr, Nd) are a\nclass of superconductors with structural similarities to cuprates. Although\nlong-range antiferromagnetic order has not been observed for these materials,\nmagn…

Superconducting vortices carrying a temperature-dependent fraction of the flux quantum Open
Magnetic field penetrates type-II bulk superconductors by forming quantum vortices that enclose a magnetic flux equal to the magnetic flux quantum. The flux quantum is a universal quantity that depends only on fundamental constants. In thi…
