Topological transition as a percolation of the Berry curvature
Han-Byul Kim, Taewon Yuk, Sang-Jin Sin
We first study the importance of the sign of the Berry curvature in the Euler characteristic of the two-dimensional topological material with two bands. Then we report an observati…
Holographic mean field theory and Kondo lattice
Young-Kwon Han, Debabrata Ghorai, Taewon Yuk +1
We first study a non-relativistic field theory model for the Kondo lattice by introducing the Kondo condensation, whose main effect is the hybridization of the flat band of the loc…
Classes of Holographic Mott Gaps
Debabrata Ghorai, Taewon Yuk, Young-Kwon Han +1
The fermion gaps are classified into order gap or Mott gap depending on the presence/absence of the order parameter. We construct the holographic model of the Mott gap using the fi…
Encoding the lattice in the Holography
Taewon Yuk, Sang-Jin Sin
One of the most wanted features of holography in its condensed matter physics application is to encode the structure of lattice, which is the most direct data of the material. In t…
