Semiconductor nanodevices as a probe of strong electron correlations
An electron is usually considered to have only one type of kinetic energy, but could it have more, for both its spin and charge, or by exciting other electrons? In one dimension (1D), the physics of interacting electrons is captured well at low energies by the linear Tomonaga- Luttinger Liquid …

Experimental consequences of mottness in high-temperature copper-oxide superconductors
… doped Mott insulators, the interaction between electrons is particularly strong. The strong electron correlations are responsible for the breakdown of Fermi-liquid behavior in the normal state. A variety of experimental probes reveal anomalous features in these materials. Such anomalies are …

Hofstadter Physics and Composite Fermionic Phase in Moiré Systems
This thesis explores the intricate electronic phenomena in Moiré systems, particularly focusing on twisted bilayer transition metal dichalcogenides (TMD). These systems, with their unique superlattice structures and strong electron correlations, provide fertile ground for investigating novel …

Effects of a single magnetic impurity on superconductivity
Electronic structure of a conventional superconductor in the vicinity of a single, iso- lated magnetic impurity has been probed experimentally with scanning tunneling spectroscopy by Yazdani et al.. Motivated by their experiment, we study the ef- fects of a single magnetic impurity on …

Search, Discovery, Synthesis and Characterization of Itinerant Magnets Composed of Non-magnetic Constituents
… local. Itinerant magnetism, caused by conduction electrons, has been of interest due to intriguing phenomena that frequently accompany it: heavy fermion behavior, coexistence of superconductivity and magnetism, metamagnetic transitions, spin- and cluster-glass behavior, multisublattice magnetism, …

Magnetotransport in superconductor to semiconductor junctions: multiple Andreev reflections and coupling to quantum hall states
Two-dimensional electron gases (2DEGs) and superconductors share many interesting properties. Both exhibit dissipationless current flow as well as strong electron correlations which can lead to a new ground state charge carrier. In this work, coupling between superconductors and 2DEGs was studied. …
