Odd-Parity Chiral Magnons in Collinear Antiferromagnetic Multiferroics
Quanchao Du, Zhenlong Zhang, Zhenlong Zhang Yuanjun Jin +9
Odd-parity magnetism represents an intriguing frontier in unconventional magnets; however, its realization has traditionally relied on noncollinear magnetic orders accompanied by b…
Systematic frequency-collision analysis of the cross-resonance gate outside the straddling regime
Shinichi Inoue, Shotaro Shirai, Shuhei Tamate +4
Frequency crowding remains a major obstacle to scaling fixed-frequency transmon processors. Among the widely used all-microwave two-qubit gates, the cross-resonance (CR) gate is pa…
High-contrast double Bragg interferometry via detuning control
Rui Li, VÃctor José MartÃnez-Lahuerta, Naceur Gaaloul +1
We propose high-contrast Mach-Zehnder atom interferometers based on double Bragg diffraction (DBD) operating under external acceleration. To mitigate differential Doppler shifts an…
Robust double Bragg diffraction via detuning control
Rui Li, V. J. MartÃnez-Lahuerta, S. Seckmeyer +2
We present a theoretical model and numerical optimization of double Bragg diffraction, a widely used technique in atom interferometry. We derive an effective two-level-system Hamil…
