Failure of the Goldstone Theorem for Vector Fields and Boundary-Mode Proliferation in Hyperbolic Lattices
Daniel Sela, Nan Cheng, Kai Sun
Hyperbolic lattices extend crystallinity into curved space, where negative curvature and exponentially large boundaries reshape collective excitations beyond Euclidean intuition. I…

Universal spectral moment theorem and its applications in non-Hermitian systems
Nan Cheng, Chang Shu, Kai Zhang +2
The high sensitivity of the spectrum and wavefunctions to boundary conditions, termed the non-Hermitian skin effect, represents a fundamental aspect of non-Hermitian systems. While…

Band theory and boundary modes of high-dimensional representations of infinite hyperbolic lattices
Nan Cheng, Francesco Serafin, James McInerney +3
Periodic lattices in hyperbolic space are characterized by symmetries beyond Euclidean crystallographic groups, offering a new platform for classical and quantum waves, demonstrati…
