Deterministic control of the probabilistic phase dynamics in injection-locked spin-torque nano-oscillators
Abderrazak Hakam, Chloé Chopin, Nhat-Tan Phan +8
Spin-torque nano-oscillators (STNOs) inherently exhibit thermally driven phase fluctuations that render their dynamics truly stochastic. Here, we demonstrate that, despite this int…

Entropy-Assisted Nanosecond stochastic operation in perpendicular superparamagnetic tunnel junctions
Lucile Soumah, Louise Desplat, Nhat-Tan Phan +7
We demonstrate a good agreement between mean dwell times measured in 50~nm diameter, perpendicularly magnetized superparamagnetic tunnel junctions (SMTJ), and theoretical predictio…

Unbiased Random Number Generation using Injection-Locked Spin-Torque Nano-Oscillators
Nhat-Tan Phan, Nitin Prasad, Abderrazak Hakam +9
Unbiased sources of true randomness are critical for the successful deployment of stochastic unconventional computing schemes and encryption applications in hardware. Leveraging na…
