Probing Green’s Function Zeros by Cotunneling through Mott Insulators
Author(s): Carl Lehmann, Lorenzo Crippa, Giorgio Sangiovanni, and Jan Carl Budich
Quantum tunneling experiments have provided deep insights into basic excitations occurring as Green’s function poles in the realm of complex quantum matter. However, strongly correlated quantum materials also allow for Green’s functions zeros (GFZs) that may be seen as an antidote to the familiar po… [Phys. Rev.
