Breakdown of Gradient-Flow Dynamics in Oscillator Ising Machines from Harmonic Misalignment
Abir Hasan, E. M. Hasantha Ekanayake, Kyle Lee +2
Oscillator Ising machines (OIMs) are often viewed as physical systems that perform gradient descent on an energy landscape encoding Ising solutions. Here, we show that this interpr…

Spin Freezing in Oscillator Ising Machines: When Second Harmonic Injection Impedes Computation
Malihe Farasat, E. M. H. E. B. Ekanayake, Nikhil Shukla
Second harmonic injection (SHI) has emerged as a critical mechanism in enabling networks of coupled oscillators to function as Oscillator Ising Machines (OIMs), capable of minimizi…
