DOI: 10.1002/adfm.202511772
Abstract: The topological structures around exceptional points (EPs) exhibit enhanced sensitivity for label‐free biosensors. However, the challenge of modifying the intrinsic topology to increase EP biosensor sensitivity remains unresolved. Here, topologically engineered EPs are utilized in… read more here.

DOI: 10.1016/j.combustflame.2019.09.018
Abstract: Abstract We propose a general classification of all the modes of a given thermoacoustic system into two sets: one of acoustic origin and one of intrinsic thermoacoustic (ITA) origin. To do this, the definition of… read more here.

DOI: 10.1017/jfm.2025.297
Abstract: Abstract Many fluid flow configurations nominally contain symmetries, which are always imperfect in real systems. In this study, we reduce the degree of rotational symmetry and break the mirror symmetry of an annular combustor’s thermoacoustic… read more here.

DOI: 10.1038/s41467-019-08826-6
Abstract: Many novel properties of non-Hermitian systems are found at or near the exceptional points—branch points of complex energy surfaces at which eigenvalues and eigenvectors coalesce. In particular, higher-order exceptional points can result in optical structures… read more here.

DOI: 10.1038/s42005-025-02220-z
Abstract: Many active matter systems consist of different particle types that interact via nonreciprocal couplings. Such nonreciprocal couplings can lead to the spontaneous emergence of time-dependent states that break parity-time symmetry. On the field-theoretical level, the… read more here.
