Ultracold fermionic atoms in disordered potentials
… the construction of an experimental apparatus to study disorder physics using ultracold fermionic atomic gases. We use this apparatus to realize 3D Anderson localization for the first time for quantum matter waves. We provide the first measurement of how the mobility edge—a hallmark of …

Transport and disorder-induced localization of ultracold Fermi gases
… in speckle and optical lattice potentials to explore Anderson localization, many-body localization, and relaxation dynamics in strongly correlated systems. Anderson localization is probed by releasing non-interacting, spin-polarized gases into three dimensional, anisotropic disordered …

Quantum Monte Carlo study of correlated electronic systems
… Quantum Monte Carlo, a powerful computational tool for the study of correlated systems, solves electron correlation problems explicitly. It has been taken as a benchmark method for understanding the correlated systems. Instead of making approximations to Hamiltonian, QMC methods work with the …

Interaction effects and disorder in two-dimensional electron systems
… The main motivation of the experiments was to study the interplay between electron-electron interactions and short-range disorder at low electron densities, while avoiding the impact of long-range charge inhomogeneities that are usually present in this regime. Indeed, several new …

Time-domain terahertz magneto-spectroscopy of semiconductors
… modes, phonons, and plasmons, just to name a few. Spectroscopic studies in this region provide valuable insights into the quantum states and dynamics of confined, driven, or interacting electrons in solids. In this dissertation research I have developed a time-domain THz …

Charge Transport Physics in Coordination Nanosheets (CONASHs)
Metal-organic frameworks (MOFs) have emerged as a versatile class of materials with intriguing properties, driven by their modular structure and tuneable functionalities. The insulating nature of most MOFs has hindered their applications which require highly conductive MOFs. A specific type of MOF …

Technological Solution beyond MOSFET and Binary Logic Device
Today’s technology is based on the binary number system-based circuitry, which is the outcome of the simple on and off switching mechanism of the prevailing transistors. Consideration of higher radix number system can eradicate or lessen many limitations of binary number system such as the …

Ultrafast photoinduced phase transitions in complex materials probed by time-resolved resonant soft x-ray diffraction
In processing and data storage mainly ferromagnetic (FM) materials are being used. Approaching physical limits, new concepts have to be found for faster, smaller switches, for higher data densities and more energy efficiency. Some of the discussed new concepts involve the material classes of …

Scanning tunneling microscopy and spectroscopy study of phase transitions and topology in layered transition metal dichalcogenides
Layered transition metal dichalcogenides (TMDs) are versatile materials which exhibit different crystal structures and different electronic behavior which ranges from metallic to semiconducting and insulating. TMDs host a large variety of physical phenomena, for instance, superconductivity, charge …
