Tilted Dirac cones and their topology in Holographic Materials
Jeong-Won Seo, Taewon Yuk, Sang-Jin Sin
We explore strongly correlated materials with tilted Dirac cone by introducing a method to realize this spectral feature within a holographic setup. Following the work by Moradpour…
Topology in Holographic Mean-Field Theory at Zero and Finite Temperature
Moongul Byun, Taewon Yuk, Young-Kwon Han +2
We investigate topological invariants in strongly interacting many-body systems within holographic mean-field theory (H-MFT) framework. Analytic expressions for retarded Green's fu…
Symmetric Tensor Coupling in Holographic Mean-Field Theory: Deformed Dirac Cones
Moongul Byun, Taewon Yuk, Sang-Jin Sin
We extend the holographic mean-field theory to rank-two symmetric tensor field as an external source coupled with fermion. We classify the roles of symmetric tensor coupling accord…
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…
