Breakdown of Local Denoising as Semantic Speciation
Guangkuo Liu, Mert Okyay, Yifan F. Zhang +3
The dynamics of generative models exhibit two apparently distinct temporal windows: a speciation window, in which a sample commits to a semantic class, and a nonlocality window, in…
Quantum Rényi-Jarzynski Equality
Benjamin Bobell, Mert Okyay, Rahul Nandkishore
The Jarzynski equality provides a strict link between nonequilibrium work and equilibrium free energy changes. Its typical quantum formulations, however, rely on measurement protoc…
Concurrence of Symmetry Breaking and Nonlocality Phase Transitions in Diffusion Models
Yifan F. Zhang, Fangjun Hu, Guangkuo Liu +2
Diffusion models undergo a phase transition in a critical time window during generation dynamics, with two complementary diagnoses of criticality. The symmetry breaking picture vie…
Exact analytic toolbox for quantum dynamics with tunable noise strength
Mert Okyay, Oliver Hart, Rahul Nandkishore +1
We introduce a framework that allows for the exact analytic treatment of quantum dynamics subject to coherent noise. The noise is modeled via unitary evolution under a Hamiltonian…
Bethe states on a quantum computer: success probability and correlation functions
Wen Li, Mert Okyay, Rafael I. Nepomechie
A probabilistic algorithm for preparing Bethe eigenstates of the spin-1/2 Heisenberg spin chain on a quantum computer has recently been found. We derive an exact formula for the su…
Nonlinear electrodynamics effects on the black hole shadow, deflection angle, quasinormal modes and greybody factors
Mert Okyay, Ali Övgün
In this paper, we discuss the effects of nonlinear electrodynamics (NED) on non-rotating black holes, parametrized by the field coupling parameter and magnetic charge parameter…
