Optical and core-level X-ray spectroscopy of correlated two-dimensional materials
… magnetic order. To understand the origin of nematicity, we investigate the ordering of the orbital degrees of freedom using X-ray linear dichroism with in-situ uniaxial strain tuning, electronic transport measurements and structural diffraction. We observe a lattice-independent orbital …

Spectroscopic studies of high-temperature superconductors on planar tunnel junction devices and nanofabricated point contact junctions
… experiments, we associate with electronic nematicity. Finally, preliminary results of planar tunnel junction devices on FeSeTe thin films and crystals to test the superconducting gap order parameter symmetry using the proximity effect are also presented.

Geometry and topological phase of matter
… which is absent in HLR theory. Due to the nematicity in ICCFL, the system supports half-quantum vortex with deconfined $\frac{\pi}{2}$ gauge flux and the phase transition toward ICCFL contains a Lifshitz criticality with $z=3$ dynamical exponent. In addition, the exciton order parameter …

Graphene-Based Nanodevices in the Superconducting and Strongly Correlated Regimes
… observed in other strongly correlated systems: nematicity and strange metal behavior. Next, I discuss local electronic compressibility measurements, evidencing that the low-temperature correlated phases originate from a high-energy state with an unusual band population sequence. Then, I describe …

Frustrated Magnetism in Strongly Correlated Electron Systems
A deep understanding of magnetism is essential for its application in magnetic semiconductors, spintronic devices and unconventional superconductors. In this work, we study magnetic structures and their corresponding excitations in several strongly correlated electron systems, where exotic …

Point contact spectroscopy studies of the iron based superconductors
Point contact spectroscopy (PCS) is used to probe both the normal and superconducting phases of the iron based superconductors. It is shown that apart from probing superconductors by Andreev reflection, PCS is also a useful technique to study exotic electron matter in correlated materials. The …

MBE growth and STM study of chalcogenide thin films
This dissertation focuses on the physics of ultra-thin films with properties influenced by their interface with the underlying substrate. Thin films have many interesting properties, of which the main one motivating the work here has been superconductivity. Studying 2D and quasi-2D systems is key …
