The types of Mott insulator
Dung-Hai Lee, Steven A. Kivelson
There are two classes of Mott insulators in nature, distinguished by their responses to weak doping. With increasing chemical potential, Type I Mott insulators undergo a first orde…
Inhomogeneity in doped Mott insulator
Dung-Hai Lee
We introduce the concept that there are two generic classes of Mott insulators in nature. They are distinguished by their responses to weak doping. Doped charges form cluster (i.e.…
Competing Order in the Mixed State of High Temperature Superconductors
Steven A. Kivelson, Dung-Hai Lee, Eduardo Fradkin +1
We examine the low temperature behavior of the mixed state of a layered superconductor in the vicinity of a quantum critical point separating a pure superconducting phase from a ph…
Transport in Inhomogeneous Strongly Correlated Systems
Darwin Chang, Dung-Hai Lee
We consider an inhomogeneous strongly correlated system where external disorder divides it into mesoscopic cells.Strong inter-particle repulsion suppresses the quantum tunneling be…
Quasiparticle Scattering Interference in High Temperature Superconductors
Qiang-Hua Wang, Dung-Hai Lee
We propose that the energy-dependent spatial modulation of the local density of states seen by Hoffman, et al [hoff2] is due to the scattering interference of quasiparticles. In th…
