Robust incoherent perfect absorption
H. S. Xu, L. Jin
A coherent perfect absorber is capable of completely absorbing input waves. However, the coherent perfect absorption severely depends on the superposition of the input waves, and t…
Berry curvature inside parity-time-symmetry protected exceptional surface
P. Wang, L. Jin, Z. Song
A three-dimensional non-Hermitian Hamiltonian with parity-time symmetry can exhibit a closed exceptional surface (EP surface) in momentum space, which is a non-Hermitian deformatio…
Edge State, Band Topology, and Time Boundary Effect in the Fine-Grained Categorization of Chern Insulators
H. C. Wu, H. S. Xu, L. C. Xie +1
We predict novel topological phases with broken time-reversal symmetry supporting the coexistence of opposite chiral edge states, which are fundamentally different from the photoni…
Pseudo-Hermiticity protects the energy-difference conservation in the scattering
H. S. Xu, L. Jin
Symmetry plays a fundamentally important role in physics. In this work, we find a conservation law, , which is valid for any non-Hermitian s…
Tunable Aharonov-Bohm cages through anti--symmetric imaginary couplings
S. M. Zhang, H. S. Xu, L. Jin
The Aharonov-Bohm (AB) cage enables localized confinement with nondiffractive propagation for arbitrary excitation. In this study, we introduce an anti-parity-time (anti-$\mathcal{…
Fundamental Neutron Physics: a White Paper on Progress and Prospects in the US
R. Alarcon, A. Aleksandrova, S. Baeßler +88
Fundamental neutron physics, combining precision measurements and theory, probes particle physics at short range with reach well beyond the highest energies probed by the LHC. Sign…
