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…
Microscopic origin of ultranodal superconducting states in spin-1/2 systems
Yifu Cao, Chandan Setty, Laura Fanfarillo +2
Several unconventional superconductors show indications of zero-energy excitations in the superconducting state consistent with the existence of a so-called Bogoliubov Fermi surfac…
Anharmonic theory of superconductivity and its applications to emerging quantum materials
Chandan Setty, Matteo Baggioli, Alessio Zaccone
The role of anharmonicity on superconductivity has often been disregarded in the past. Recently, it has been recognized that anharmonic decoherence could play a fundamental role in…
Possible enhancement of the superconducting due to sharp Kohn-like soft phonon anomalies
Cunyuan Jiang, Enrico Beneduce, Matteo Baggioli +2
Phonon softening is a ubiquitous phenomenon in condensed matter systems which is often associated with charge density wave (CDW) instabilities and anharmonicity. The interplay betw…
Exact solution for finite center-of-mass momentum Cooper pairing
Chandan Setty, Jinchao Zhao, Laura Fanfarillo +4
Pair density waves (PDWs) are superconducting states formed by ``Cooper pairs" of electrons containing a non-zero center-of-mass momentum. They are characterized by a spatially mod…
Theory of Superconductivity Mediated by Topological Phonons
Daniele Di Miceli, Chandan Setty, Alessio Zaccone
Topological phononic insulators are the counterpart of three-dimensional quantum spin Hall insulators in phononic systems and, as such, their topological surfaces are characterized…
