Bkt theory

WebAt the present time, the BKT paradigm plays a central role in the understanding of thin film superconductors, Josephson junction arrays, and complex compounds which have weakly coupled layers, such as many of the high temperature superconductors. The limitations of space preclude a discussion of many issues that are of contemporary interest. WebJan 23, 2024 · Bissinger, “The BKT transition in the mobile XY model,” Ph.D. thesis, University of Konstanz, 2024. We will call the low temperature regime the spin wave phase. The crucial ingredient to a spin wave theory is the approximation of the spin–spin interaction by an effective harmonic Hamiltonian.
