# Custodial chiral symmetry in SSH memcircuits

@inproceedings{Ventra2021CustodialCS, title={Custodial chiral symmetry in SSH memcircuits}, author={Massimiliano Di Ventra and Yuriy V. Pershin and Chih-Chun Chien}, year={2021} }

Custodial symmetries are common in the Standard Model of particle physics. They arise when quantum corrections to a parameter are proportional to the parameter itself. Here, we show that a custodial symmetry of the chiral type is also present in a classical Su-Schrieffer-Heeger (SSH) electrical circuit with memory (memcircuit). In the absence of memory, the SSH circuit supports a symmetry-protected topological edge state. Memory induces nonlinearities that break chiral symmetry explicitly and… Expand
