Exceptional points in non-Hermitian Hamiltonians correspond to multi-block exceptional points in the no-jump Liouvillian; quantum jump terms modify the block structure, demonstrated in qubit and qutrit models with population sinks.
Non-Hermitian skin effect in Rashba nanowire with ferromagnetic lead produces nonreciprocal nonlocal conductance detectable by transport spectroscopy, with exceptional points shifting under open boundary conditions.
Exceptional points in a minimal multiterminal SN junction produce visible signatures in Andreev spectroscopy but only minor effects on Josephson current.
