Shot noise and universal Fano factor as characterization of strongly correlated metals
Yiming Wang, Chandan Setty, Shouvik Sur +4
Shot noise measures out-of-equilibrium current fluctuations and is a powerful tool to probe the nature of current-carrying excitations in quantum systems. Recent shot noise measure…
Symmetry constraints and spectral crossing in a Mott insulator with Green's function zeros
Chandan Setty, Shouvik Sur, Lei Chen +5
Lattice symmetries are central to the characterization of electronic topology. Recently, it was shown that Green's function eigenvectors form a representation of the space group. T…
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…
