Stringlet Excitation Model of the Boson Peak
Cunyuan Jiang, Matteo Baggioli, Jack F. Douglas
The boson peak (BP), a low-energy excess in the vibrational density of states over the Debye contribution, is often identified as a characteristic of amorphous solid materials. Des…
A quantitative theoretical model of the boson peak based on stringlet excitations
Cunyuan Jiang, Matteo Baggioli, Jack F. Douglas
The boson peak (BP), a low-energy excess in the vibrational density of states over the phonon Debye contribution, is usually identified as one of the distinguishing features betwee…
Correlation between optical phonon softening and superconducting in YBaCuO within -wave Eliashberg theory
Cunyuan Jiang, Giovanni A. Ummarino, Matteo Baggioli +2
We provide a mathematical description, based on d-wave Eliashberg theory, of the strong correlation between the experimentally observed softening of Raman modes associated with in-…
Engineering flat bands in twisted-bilayer graphene away from the magic angle with chiral optical cavities
Cunyuan Jiang, Matteo Baggioli, Qing-Dong Jiang
Twisted bilayer graphene (TBG) is a recently discovered two-dimensional superlattice structure which exhibits strongly-correlated quantum many-body physics, including strange metal…
Glassy heat capacity from overdamped phasons and a hypothetical phason-induced superconductivity in incommensurate structures
Cunyuan Jiang, Alessio Zaccone, Chandan Setty +1
Phasons are collective low-energy modes that appear in disparate condensed matter systems such as quasicrystals, incommensurate structures, fluctuating charge density waves, and Mo…
Constrains on s and d components of electron boson coupling constants in one band d wave Eliashberg theory for high Tc superconductors
Giovanni Alberto Ummarino
The phenomenology of overdoped high Tc superconductors can be described by a one band d wave Eliashberg theory where the mechanism of superconducting coupling is mediated by antife…
