Calculations of current in the cotunneling regime using Lindblad equations
Kian Maleki, Michael E. Flatté
Transport through zero-dimensional states in a tunneling barrier can occur via co-tunneling, wherein a carrier occupying a state outside the range of energies between the chemical…
Strong coupling between quantized magnon modes in a YIG microstucture and microwaves in a superconducting resonator
Seth W. Kurfman, Philipp Geyer, Anoop Kamalasanan +6
Strong-coupling experiments based on magnons enable the exploration into on-chip demonstrations involving numerous long-lived excitations. Yttrium iron garnet (YIG) has been consid…
Imaging Harmonic Generation of Magnons
Anthony J. D'Addario, Kwangyul Hu, Maciej W. Olszewski +4
This work combines theory and experiment to examine the mechanisms underlying the harmonic generation of magnons. We develop a nonlinear spin-wave framework that is directly analog…
Imaging the high-frequency charging dynamics of a single impurity in a semiconductor on the atomic scale
Maialen Ortego Larrazabal, Jiasen Niu, Stephen R. McMillan +4
As electronic devices approach the atomic limit, the charge dynamics of individual dopant atoms increasingly constrain performance, stability, and coherence. In scanning tunnelling…
Spatial structure and magnetism of a spin-orbit entangled spin-1 coherent spin center: the manganese neutral acceptor in a III-V semiconductor
Julian Zanon, Michael E. Flatté
A Mn dopant in a III-V semiconductor produces a highly-entangled, coherent triplet ground state not fully captured by single-determinant theories of electron structure. We directly…
Single Color Center Spin Coherence revealed in Optically Detected Magnetic Resonance of an Ensemble of Silicon Vacancies in SiC
David A. Fehr, Hannes Kraus, Corey J. Cochrane +1
We present a quantitative theory for simulating optically detected magnetic resonance (ODMR) measurements of optically-active spin centers using steady-state Lindblad equations. We…
