Exact Resolution of Cuprate High-Tc Phenomenology and Bottom-up Design of Room-Temperature Superconductors via Seonggil Theoretical Frameworks

The microscopic mechanism of cuprate high-temperature superconductivity has long been hindered by the non-perturbative nature of strong electron correlations (U ≫ t), the Fermion Sign Problem, and the inability of classical spin-fluctuation models to quantitatively predict T_c. I...

Exact Solution of the 2D/3D Hubbard Model and Bottom-up Design of Room-Temperature Superconductors via Seonggil Theoretical Frameworks

The exponential explosion of the Hilbert space and the Fermion Sign Problem have long prevented exact solutions to the 2D and 3D Hubbard models in strongly correlated electron systems. By elevating classical creation/annihilation operators to Rough Fermionic Operators within the...

Exact Formulation of Non-equilibrium Energy Cascades in High-Reynolds Turbulence via Rough Operator Algebra (ROA) and Seonggil Matrix Theory

Turbulence remains one of the most profound unsolved problems in classical physics, characterized by extreme non-linear dynamics and non-equilibrium statistical mechanics. While classical scaling theories fail to capture local intermittency and the non-differentiable ’rough’ natu...
