Visualizing the Nonlinear Coupling between Strain and Electronic Nematicity in the Iron Pnictides by Elasto-Scanning Tunneling Spectroscopy
Erick F. Andrade, Ayelet Notis Berger, Ethan P. Rosenthal +7
Mechanical strain is a powerful technique for tuning electronic structure and interactions in quantum materials. In a system with tetragonal symmetry, a tunable uniaxial in-plane s…
Disentangling lattice and electronic contributions to the metal-insulator transition from bulk vs. layer confined RNiO
Alexandru B. Georgescu, Oleg E. Peil, Ankit Disa +2
In complex oxide materials, changes in electronic properties are often associated with changes in crystal structure, raising the question of the relative roles of the electronic an…
Intermolecular Coupling and Superconductivity in Chevrel Phase Compounds
Jia Chen, Andrew J. Millis, David R. Reichman
To understand superconductivity in Chevrel phase compounds and guide the search for interesting properties in materials created with Chevrel phase molecules as building blocks, we…
The antiferromagnetic phase of the Floquet-driven Hubbard model
Nicklas Walldorf, Dante M. Kennes, Jens Paaske +1
A saddle point plus fluctuations analysis of the periodically driven half-filled two-dimensional Hubbard model is performed. For drive frequencies below the equilibrium gap, we fin…
Loschmidt-amplitude wave function spectroscopy and the physics of dynamically driven phase transitions
D. M. Kennes, C. Karrasch, A. J. Millis
We introduce the Loschmidt amplitude as a powerful tool to perform spectroscopy of generic many-body wave functions and use it to interrogate the wave function obtained after rampi…
Voltage induced metal-insulator transition in a one dimensional charge density wave
Giuliano Chiriacò, Andrew J. Millis
We present a theoretical investigation of the voltage-driven metal insulator transition based on solving coupled Boltzmann and Hartree-Fock equations to determine the insulating ga…
