Correlation, superconductivity, and topology in twisted and untwisted layered systems
This thesis is an effort to understand some of the interesting features induced by strong correlation - superconductivity, topology, non-Fermi liquid (NFL) in two dimensional (2D) layered materials. 2D layered materials ...
The role of quantum fluctuations in the t-J model: Implications for cuprate superconductors
The physics of strongly correlated electron systems is among the central problems of condensed matter physics. One of the outstanding problems in this category is that of the high-Tc superconductivity obtained by doping ...
Probing charge-density waves and superconductivity in low-dimensional systems
The recent advent of two-dimensional materials has led to the discovery of materials
with fascinating phase diagrams. These systems have exciting electronic phases which
coexist or compete with each other. Here in this ...
Induced p-wave superconductivity in a dual topological insulator BiTe and unconventional superconductivity in a magnetic topological insulator MnBi2Te4
The discovery of topological insulators (TI) and semimetals has led to a whole new world of low-energy electronic devices that enable dissipationless transport through their highly spin-orbit coupled conducting channels. ...
Thermopower probing the effect of interaction and strong correlation in twisted multilayer graphene moir´e
Two-dimensional quantum materials, especially graphene-based van der Waals heterostructures, have been at the forefront of a new era in scientific research and technological breakthroughs. From field-effect transistors to ...
