Degeneracy beyond the parity-symmetry protection in one-dimensional spinless models: The parity-violating Kerr parametric oscillator
A parity-violating Kerr parametric oscillator exhibits doubly-degenerate levels via antiunitary symmetry, showing spontaneous symmetry breaking is possible without parity protection.
