Eigenframe Synchronization in Disordered Driven Quantum Ensembles
Saipriya Satyajit, Zechuan Yin, Jner Tzern Oon +5
Periodic driving underlies many forms of quantum control, including spin-based quantum sensing. However, in an ensemble sensor, one waveform must act on spins with different detuni…
Spatially Resolving the Pre-Thermal Anatomy of a Driven Bosonic Fluid
Shantam Ravan, Aaron Müller, Johannes Cremer +5
Understanding how coherently driven quantum many-body systems redistribute energy prior to thermal equilibrium remains a central challenge in many-body physics. Here, we utilize ni…
Noise Suppression via Pulsed All-Optical Magnetometry with Nitrogen-Vacancy Ensembles
Xiechen Zheng, Jeyson Támara-Isaza, John W. Blanchard +1
All-optical (AO) microwave-free magnetometry using nitrogen-vacancy (NV) centers in diamond simplifies experimental design and broadens sample compatibility. While continuous-wave…
Multi-scale reconstruction of single-ion damage tracks in diamond via nitrogen-vacancy centers
Daniel G. Ang, Jiashen Tang, Maximilian Shen +9
Understanding particle-induced damage tracks in solid-state materials underpins emerging applications in rare-event detection and quantum defect engineering. Resolving these tracks…
A nanoscale magnetic spectrum analyzer based on qubit dressed states
Jan Rueschkamp, Shantam Ravan, Daniel Fernandez +6
Magnetic field fluctuations on nanometer length scales manifest in a diverse range of phenomena -- electron and spin dynamics in materials and devices, quantum many-body systems, a…
Demonstrating magnetic memory in iron-rhodium structures using a quantum diamond microscope
Kristine V. Ung, Gregory M. Stephen, Nicholas A. Blumenschein +7
Iron-rhodium (FeRh) has a first-order phase transition near room temperature between antiferromagnetic (AFM) and ferromagnetic (FM) phases, making it a promising material for magne…
