Spectral asymmetry

Spectral asymmetry refers to the property of a spectral distribution where the spectrum (eigenvalue distribution or frequency spectrum) of a given operator or system does not exhibit symmetry around a particular point, typically zero. In many physical systems, particularly in quantum mechanics or systems described by linear operators, eigenvalues can be distributed symmetrically, meaning if \( \lambda \) is an eigenvalue, then \( -\lambda \) is also an eigenvalue.
