Dynamical Control of Superconductivity in Superconductor-Ferromagnet Bilayers
Dimitri Pimenov, Nicholas R. Poniatowski, Charlotte G. L. Bøttcher +2
We study a simplified model of a ferromagnetic metal proximitized by a fully-gapped wave superconductor and integrated with a microwave resonator. The low-energy excitations in…
Probing the Berezinskii-Kosterlitz-Thouless vortex unbinding transition in two-dimensional superconductors using local noise magnetometry
Jonathan B. Curtis, Nikola Maksimovic, Nicholas R. Poniatowski +4
The melting of quasi-long-range superconductivity in two spatial dimensions occurs through the proliferation and unbinding of vortex-antivortex pairs -- a phenomenon known as the B…
Circuit QED detection of induced two-fold anisotropic pairing in a hybrid superconductor-ferromagnet bilayer
C. G. L. Bøttcher, N. R. Poniatowski, A. Grankin +5
Hybrid systems represent one of the frontiers in the study of unconventional superconductivity and are a promising platform to realize topological superconducting states. Owing to…
Stabilizing fluctuating spin-triplet superconductivity in graphene via induced spin-orbit coupling
Jonathan B. Curtis, Nicholas R. Poniatowski, Yonglong Xie +3
A recent experiment showed that proximity induced Ising spin-orbit coupling enhances the spin-triplet superconductivity in Bernal bilayer graphene. Here, we show that, due to the n…
Proximity-induced collective modes in an unconventional superconductor heterostructure
Jonathan B. Curtis, Nicholas R. Poniatowski, Amir Yacoby +1
Unconventional superconductors have been long sought for their potential applications in quantum technologies and devices. A key challenge impeding this effort is the difficulty as…
Surface Cooper pair spin waves in triplet superconductors
Nicholas R. Poniatowski, Jonathan B. Curtis, Charlotte G. L. Bøttcher +4
We study the electrodynamics of spin triplet superconductors including dipolar interactions, which give rise to an interplay between the collective spin dynamics of the condensate…
A counterexample to the conjectured Planckian bound on transport
Nicholas R. Poniatowski, Tarapada Sarkar, Ricardo P. S. M. Lobo +2
It has recently been conjectured that the transport relaxation rate in metals is bounded above by the temperature of the system. In this work, we discuss the transport phenomenolog…
Cavity magnon-polaritons in cuprate parent compounds
Jonathan B. Curtis, Andrey Grankin, Nicholas R. Poniatowski +3
Cavity control of quantum matter may offer new ways to study and manipulate many-body systems. A particularly appealing idea is to use cavities to enhance superconductivity, especi…
Spectroscopic signatures of time-reversal symmetry breaking superconductivity
Nicholas R. Poniatowski, Jonathan B. Curtis, Amir Yacoby +1
The collective mode spectrum of a symmetry-breaking state, such as a superconductor, provides crucial insight into the nature of the order parameter. In this context, we present a…
