SPICE Workshop on Ferrons and Magnons: friends or foes? July 7th - 9th, 2026
Davi Rodrigues
Condensed-matter excitations provide a promising route toward unconventional computing by combining intrinsic nonlinearity, fast dynamics and scalability in compact physical platforms. In this talk, we discuss two complementary directions based on magnons and ferrons. On the magnonic side, we present recent results on an all-magnonic neuron with threshold activation, self-reset and tunable fading memory, including temporal integration of up to 50 magnon pulses, a three-order-of-magnitude tuning of the memory time, and cascaded triggering of three neurons. This work establishes a route toward interconnected magnonic neuromorphic circuits. On the ferroelectric side, we introduce a GPU-native solver for polarization dynamics that resolves the full vector order parameter and electrostatic field, enabling large-scale simulations beyond the limits of current reduced models. We show how this framework reproduces domain-wall benchmarks, phase transitions and field-driven hysteresis, and how it supports predictive studies of ferron dynamics in finite systems. Together, these results show that improved control of magnons and accurate large-scale modelling of ferrons can support the development of unconventional computing concepts based on ferroic excitations, and strengthen their prospects as hardware platforms for future electronics.
