Drift Estimation for a Multi-Dimensional Lévy-Driven Stochastic Differential Equation Using Deep Neural Networks
Taisei Noguchi, Teppei Ogihara
We develop a non-asymptotic theory for nonparametric drift estimation in discretely observed multi-dimensional Lévy-driven stochastic differential equations using sparse ReLU neura…
Discrete quality-factor control in a side-coupled photonic crystal microcavity: evanescent Bloch tunnelling and the finite-cell correction
Hasan Oguz
A point-defect cavity side-coupled to a line-defect waveguide in a two-dimensional photonic crystal of silicon rods in water is studied with plane-wave expansion and finite-differe…
Generalized Thermodynamics of Solitonic Event Horizons in Dispersive Field Theories
Hasan Oguz
The realization of Hawking radiation in optical analogs has historically focused on kinematic observables, such as the effective temperature determined by the horizon's surface gra…
Geometric Optimization and IPA-Induced Dispersion Tuning in Solid-Core Photonic Crystal Fibers
Zekeriya Mehmet Yuksel, Hasan Oguz, Ozgur Onder Karakilinc +4
This study presents a numerical investigation of solid-core photonic crystal fibers with circular and hexagonal cladding geometries. The goal is to optimize optical parameters for…
Authoritarian Recursions: How Fiction, History, and AI Reinforce Control in Education, Warfare, and Discourse
Hasan Oguz
This article introduces the concept of \textit{authoritarian recursion} to theorize how AI systems consolidate institutional control across education, warfare, and digital discours…
The Effect of Symmetry Breaking in Coupled Cavity Photonic Crystal Waveguide on Dispersion Characteristics
Hasan Oguz, Zekeriya Mehmet Yuksel, Ozgur Onder Karakilinc +4
In this study, we explore the effect of integrated auxiliary rods at varying angles to the primary cavity rod on the dispersion characteristics of the photonic crystal coupled cavi…
Enhanced self-collimation effect by low rotational symmetry in hexagonal lattice photonic crystals
Zekeriya Mehmet Yuksel, Hasan Oguz, Ozgur Onder Karakilinc +4
In this study, we present the design of a photonic crystal (PC) structure with a hexagonal lattice, where adjustments to the PC unit cell symmetry reveal an all-angle self-collimat…
