Exceptional Bound States and negative Entanglement Entropy
Ching Hua Lee
This work introduces a new class of robust states known as Exceptional Boundary (EB) states, which are distinct from the well-known topological and non-Hermitian skin boundary stat…
Nonlinearity induced topological physics in momentum space and real space
Thomas Tuloup, Raditya Weda Bomantara, Ching Hua Lee +1
Nonlinearity induced topological properties in nonlinear lattice systems are studied in both momentum space and real space. Experimentally realizable through the Kerr effect on pho…
Many-Body Topological and Skin States without Open Boundaries
Ching Hua Lee
Robust boundary states have been the focus of much recent research, both as topologically protected states and as non-Hermitian skin states. In this work, we show that many-body ef…
Critical non-Hermitian Skin Effect
Linhu Li, Ching Hua Lee, Sen Mu +1
This work uncovers a new class of criticality where eigenenergies and eigenstates of non-Hermitian lattice systems jump discontinuously across a critical point in the thermodynamic…
Quenched topological boundary modes can persist in a trivial system
Ching Hua Lee, Justin C. W. Song
Topological boundary modes can occur at the spatial interface between a topological and gapped trivial phase and exhibit a wavefunction that exponentially decays in the gap. Here w…
