I am a quantum device theorist interested in the design and simulation of quantum processors, both for fundamental … WitrynaIt is well known that amorphous solids display a phonon spectrum where the Debye ∼ω2 law at low frequency melds into an anomalous excess-mode peak (the boson peak) before entering a quasi-localized regime at higher frequencies dominated by scattering. The microscopic origin of the boson peak has remained elusive despite various …

WitrynaSymmetry is regularly used to derive conservation laws and selection rules in interacting systems ().In the field of nonlinear optics, symmetries are standardly used to determine whether a particular nonlinear process is allowed or forbidden according to the medium’s point group (2, 3).Recently, a more general group theory was developed to describe … Witrynathat the microscopic origin of the boson peak is directly controlled by the local breaking of center-inversion symmetry. In particular, we nd that both the boson peak and the nona ne softening of the material display a strong positive correlation with a new order parameter describing the local inversion symmetry of the lattice.
