Unraveling non-Hermitian pumping: emergent spectral singularities and anomalous responses
Ching Hua Lee, Linhu Li, Ronny Thomale +1
Within the expanding field of non-Hermitian physics, non-Hermitian pumping has emerged as a key phenomenon, epitomized through the skin effect via extensive boundary mode accumulat…
Emergent Fermi surface in a many-body non-Hermitian Fermionic chain
Sen Mu, Ching Hua Lee, Linhu Li +1
Quantum degeneracy pressure (QDP) underscores the stability of matter and is arguably the most ubiquitous many-body effect. The associated Fermi surface (FS) has broad implications…
Topology-Induced Spontaneous Non-reciprocal Pumping in Cold-Atom Systems with Loss
Linhu Li, Ching Hua Lee, Jiangbin Gong
We propose a realistic cold-atom quantum setting where nontrivial energy-band topology induces non-reciprocal pumping. This is an intriguing non-Hermitian phenomenon that illustrat…
Boundary states of 4D topological matter: Emergence and full 3D-imaging of nodal Seifert surfaces
Linhu Li, Ching Hua Lee, Jiangbin Gong
With its boundary tracing out a link or knot in 3D, the Seifert surface is a 2D surface of core importance to topological classification. We propose the first-ever experimentally r…
Geometric classification of non-Hermitian topological systems through the singularity ring
Linhu Li, Ching Hua Lee, Jiangbin Gong
This work unveils how geometric features of two-band non-Hermitian Hamiltonians can completely classify the topology of their eigenstates and energy manifolds. Our approach general…
