We consider extended versions of the Hubbard model which contain additional interactions between nearest neighbors. In this Letter we show that a large class of these models has a superconducting ground state in arbitrary dimensions. In some special cases we are able to find the complete phase diagram. The superconducting phase exists even for moderate repulsive values of the Hubbard interaction $U$ .We consider extended versions of the Hubbard model which contain additional interactions between nearest neighbors.

太极统一场论——太极量子力学与室温超导机理 Tai Chi Unified Field Theory: Tai Chi Quantum Mechanics and Room-Temperature Superconductivity Mechanism

Hechun Sun

本文以太极阴阳体系为公理基础,建立自洽、严谨且数学完备的太极统一场论,重构太极量子力学,并构建适用于常压室温超导的太极库珀对模型。理论以阴阳对偶常数 K=-1 为核心,统一解释波粒二象性、量子纠缠、不确定性原理、量子隧穿等微观量子现象。同时,本文脱离传统声子机制,由阴阳互根作用直接导出电子自发配对条件,为室温超导提供全新的物理机理。全文公理清晰、推导严谨、物理意义明确,形成可直接用于学术发表的完整理论体系。Based on the axiomatic system of Tai Chi Yin-Yang, this paper establishes a self-consistent, rigorous and mathematically complete Tai Chi Unified Field Theory, reconstructs Tai Chi Quantum Mechanics, and constructs a Tai Chi Cooper pair model suitable for ambient-pressure room-temperature superconductivity. With the Yin-Yang dual constant K=-1 as the core, the theory uniformly explains microscopic quantum phenomena such as wave-particle duality, quantum entanglement, uncertainty principle and quantum tunneling. Furthermore, breaking away from the traditional phonon mechanism, this work directly derives the spontaneous electron pairing condition from the interaction of Yin-Yang interdependence, providing a brand-new physical mechanism for room-temperature superconductivity. The full text has clear axioms, rigorous derivations and definite physical significance, forming a complete theoretical system that can be directly used for academic publication.本文以太极阴阳体系为公理基础,建立自洽、严谨且数学完备的太极统一场论,重构太极量子力学,并构建适用于常压室温超导的太极库珀对模型。理论以阴阳对偶常数 K=-1 为核心,统一解释波粒二象性、量子纠缠、不确定性原理、量子隧穿等微观量子现象。同时,本文脱离传统声子机制,由阴阳互根作用直接导出电子自发配对条件,为室温超导提供全新的物理机理。全文公理清晰、推导严谨、物理意义明确,形成可直接用于学术发表的完整理论体系。Based on the axiomatic system of Tai Chi Yin-Yang, this paper establishes a self-consistent, rigorous and mathematically complete Tai Chi Unified Field Theory, reconstructs Tai Chi Quantum Mechanics, and constructs a Tai Chi Cooper pair model suitable for ambient-pressure room-temperature superconductivity.
