# Clapping Modes in Unconventional Superconductors

Searching arXiv for recent papers on clapping modes across superconductivity and fluid mechanics.
Clapping modes are collective excitations associated with internal relative oscillations between components of an ordered state. In contemporary arXiv literature, the term is used most precisely in unconventional superconductivity, where it denotes the relative amplitude and relative phase modes between two chiral components of Cooper pairs, such as the \(k_x+i k_y\) and \(k_x-i k_y\) sectors of a chiral \(p\)-wave state. These excitations are bosonic, generically sub-gap, and often long-lived; their spectroscopic and transport signatures have become a central route to identifying chiral and more general time-reversal-symmetry-breaking superconductivity [2112.12710]. The same word also appears in fluid mechanics, flight biomechanics, and nanomechanics, but there it refers to closing-body or sequential-mode kinematics rather than to an order-parameter collective mode.
