Chiral symmetry breaking and violation of the Wiedemann-Franz law in underdoped cuprates
Guo-Zhu Liu, Geng Cheng
We propose that the recently observed violation of the Wiedemann-Franz law in the normal state of underdoped cuprates is caused by spin-charge separation and dynamical chiral symme…

A Generalized Parameter Imbedding Method
Cheng Geng, T. K. Kuo
The parameter imbedding method for the Fredholm equation converts it into an initial value problem in its parameter . We establish the method for general operator equations of t…

An extension of Anderson-Higgs mechanism
Guo-Zhu Liu, Geng Cheng
When free vortices are present in the pseudogap region of underdoped cuprates, it is shown that conventional Anderson-Higgs mechanism does not work because the Goldstone field is n…
