Temperature dependence of spin-model parameters in ferrimagnets
Marta Yanguas, José M. Lendínez, Theodor Griepe +3
We compute the temperature dependence of effective spin-model parameters in two-sublattice ferrimagnets with antiparallel and inequivalent sublattice magnetizations using Green's-f…
Quantum Codes with Arbitrary Z-Rotation logical Gates and Applications to Fault-Tolerant Code Switching
Reza Dastbasteh, Ruben M. Otxoa, Pedro M. Crespo +1
A technique for realizing a universal set of fault-tolerant quantum operations is the code switching method, which leverages two quantum codes with complementary sets of transversa…
Moving Analogue Horizons in Stationary Ferroelectrics
David Galvez-Poblete, Rubén M. Otxoa, Alvaro S. Nunez +1
We show that a traveling modulation of the polarization-gradient stiffness in a ferroelectric material induces an effective flow in its collective polarization dynamics. Within a c…
A spin-bond theory unifying non-relativistic spin splitting and emergent spin-orbit textures
S. Allende, R. M. Otxoa
Magnetic order with vanishing net magnetization can produce non-relativistic spin-split bands, broadly categorized into even-parity altermagnets and odd-parity \(p\)-wave magnets.…
Spin-orbit torque-driven synthetic antiferromagnetic oscillator
P. K. Rout, J. Godinho, F. Vilsmeier +9
Antiferromagnets offer a promising route toward robust spintronic devices because of their compensated magnetic order and exchange-enhanced spin dynamics. Here, we demonstrate a sp…
Universal theory of domain-wall width in multi-sublattice Heisenberg magnets
José M. Lendínez, Marta Yanguas, Theodor Griepe +4
We propose a universal expression for the domain-wall width in generic multi-sublattice Heisenberg magnets, applicable to ferro-, antiferro-, and ferrimagnetic orders. The result f…
Hardware-Tailored Resource Estimation for Magic-State Distillation on Silicon Spin Qubits
Songqinghao Yang, Christopher K. Long, Rubén M. Otxoa +3
We present a resource analysis for generating high-fidelity logical magic states on silicon spin-qubit platforms. We consider a range of architectures, including a shuttling-based…
Surface-Code Thresholds and Qubit Footprints in Shuttling-Based Spin-Qubit Railways
Arun John Moncy, Reza Dastbasteh, Josu Etxezarreta Martinez +5
We present a fault-tolerant mapping of rotated surface codes onto a silicon spin-qubit railway architecture, utilizing electron shuttling to resolve the wiring fan-out…
Valley enhanced Rabi frequency in n-type planar Silicon-MOS quantum dot
Xunyao Luo, Xander Peetroons, Tsung-Yeh Yang +27
Electron spin resonance spectroscopy (ESR) of a single electron in planar Si-MOS quantum dot is reported in the vicinity of a valley level anti-crossing. A number of one and two-ph…
Exact Solution for Current-Driven Domain-Wall Dynamics Beyond Lorentz Contraction in Antiferromagnets with Dzyaloshinskii-Moriya Interaction
Mu-Kun Lee, Rubén M. Otxoa, Masahito Mochizuki
We study current-driven domain-wall (DW) dynamics in antiferromagnets (AFMs) with Dzyaloshinskii-Moriya interaction (DMI). We obtain an exact analytical solution for spiral DW dyna…
