'Grey Galaxies' as an endpoint of the Kerr-AdS superradiant instability
Seok Kim, Suman Kundu, Eunwoo Lee +3
Kerr-AdS black holes for suffer from classical superradiant instabilities over a range of masses above extremality. We conjecture that these instabilities settle…
The shape of non-graviton operators for
Sunjin Choi, Seok Kim, Eunwoo Lee +1
The BPS spectrum of AdS/CFT exhibits multi-gravitons at low energies, while having black hole states at higher energies. This can be studied concretely in AdS/CFT in terms…
From giant gravitons to black holes
Sunjin Choi, Seok Kim, Eunwoo Lee +1
We study AdS black holes from a recently suggested giant graviton expansion formula for the index of maximal super-Yang-Mills theory. We compute the large entropy at…
Exact QFT duals of AdS black holes
Sunjin Choi, Saebyeok Jeong, Seok Kim +1
We construct large saddle points of the matrix model for the Yang-Mills index dual to the BPS black holes in , in two different setups. When th…
Many-body approach to non-Hermitian physics in fermionic systems
Eunwoo Lee, Hyunjik Lee, Bohm-Jung Yang
In previous studies, the topological invariants of 1D non-Hermitian systems have been defined in open boundary condition (OBC) to satisfy the bulk-boundary correspondence. The extr…
Sign-tunable anomalous Hall effect induced by two-dimensional symmetry-protected nodal structures in ferromagnetic perovskite oxide thin films
Byungmin Sohn, Eunwoo Lee, Se Young Park +16
Magnetism and spin-orbit coupling (SOC) are two quintessential ingredients underlying novel topological transport phenomena in itinerant ferromagnets. When spin-polarized bands sup…
Two-dimensional higher-order topology in monolayer graphdiyne
Eunwoo Lee, Rokyeon Kim, Junyeong Ahn +1
Based on first-principles calculations and tight-binding model analysis, we propose monolayer graphdiyne as a candidate material for a two-dimensional higher-order topological insu…
Fractional charge bound to a vortex in two dimensional topological crystalline insulators
Eunwoo Lee, Akira Furusaki, Bohm-Jung Yang
We establish the correspondence between the fractional charge bound to a vortex in a textured lattice and the relevant bulk band topology in two-dimensional (2D) topological crysta…
