Quantum geometric origins of the orbital degrees of freedom of hybrid bosonic quasiparticles in magnetic systems
D. Quang To, Dai Q. Ho, Joshua M. O. Zide +5
The orbital degree of freedom has recently attracted significant attention due to the novel phenomena it enables in condensed matter systems. However, the interpretation of the orb…
Probing Magnetic Properties of RuO Heterostructures Through the Ferromagnetic Layer
Frank M. Abel, Subhash Bhatt, Shelby S. Fields +20
RuO has been proposed as the prototypical altermagnetic material. However, several reports have recently questioned its intrinsic magnetic ordering, leading to conflicting fi…
A method for determining the Zeeman splitting of a spin qubit via Rabi-driven tunneling
Emily Townsend, Joshua Pomeroy, Garnett W. Bryant
We show that resonant driving between the spin up and spin down states of an electron spin-qubit in a quantum dot reduces the occupancy of the dot through leakage to an appropriate…
Atomistic tight-binding Hartree-Fock calculations of multielectron configurations in P-doped silicon devices: wavefunction reshaping
Maicol A. Ochoa, Keyi Liu, Piotr Różański +2
Donor-based quantum devices in silicon are attractive platforms for universal quantum computing and analog quantum simulations. The nearly-atomic precision in dopant placement prom…
Symmetry-breaking induced surface magnetization in non-magnetic RuO
Dai Q. Ho, D. Quang To, Ruiqi Hu +2
Altermagnetism is a newly identified phase of magnetism distinct from ferromagnetism and antiferromagnetism. RuO has been considered a prototypical metallic altermagnet with a…
Tunable magnon band topology and magnon orbital Nernst effect in noncollinear antiferromagnets
D. Quang To, Dai Q. Ho, Joshua M. O. Zide +5
We theoretically investigate the intrinsic magnon orbital Nernst effect (ONE) in noncollinear antiferromagnets with Kagomé spin systems. Our analysis reveals that an externally app…
