Angle-Resolved Photoemission Spectroscopy and its application to the study of the electronic structure of some correlated-electron systems

In solids with strongly-interacting electrons, the competition between the different degrees of freedom leads to competing quantum ground states, from which a rich variety of macroscopic phenomena emerge. In many cases, these phenomena arise from phase transitions described by exotic … Continue reading

Tuning the electronic properties of oxide heterostructures using electrostatic gating and coherent light

Complex oxide heterostructures exhibit functional electronic properties such as magnetism and superconductivity. An important step toward the use of quantum materials in real-word applications is to achieve on-demand control of their ground state. One strategy consists in applying static electric … Continue reading

Optical Properties of (SrMnO$_3$)$_n$/(LaMnO$_3$)$_{2n}$ Superlattices: An Insulator-to-Metal Transition Observed in the Absence of Disorder

We measure the optical conductivity, $\sigma_1(\omega)$, of (SrMnO$_3$)$_n$/(LaMnO$_3$)$_{2n}$ superlattices (SL) for n=1, 3, 5, and 8 and 10 < T < 400 K. Data show a T-dependent insulator to metal transition (IMT) for n=3, driven by the softening of a … Continue reading

Enhancement of the superconducting transition temperature in cuprate heterostructures

We observe enhancement of the superconducting transition temperature in heterostructures of superconducting oxides.  Fabrication of multilayer thin films of $La_{2−x}Ce_{x}CuO_{4}$ (LCCO) and $Pr_{2−x}Ce_{x}CuO_{4}$ (PCCO) paired over-doped and under-doped (or un-doped) layers of various layer thicknesses.  An increased $T_c$ was observed, … Continue reading

Orbital reconstruction at YBa2Cu3O7/La2/3Sr1/3MnO3 interfaces revealed by resonant inelastic x-ray scattering

Transition metal oxide hetero-interfaces have been attracting great attention due to extraordinary phenomena not exhibited by either of the constituent materials alone. A particularly fascinating system is the ferromagnetic/superconducting heterostructure which has vast application in the area of spintronics. Recent … Continue reading
