Momentum-resolved electron dynamics in a strange metal
Submission original under an indefinite embargo labeled 'Open Access'. The submission was exported from vireo on 2025-10-20 without embargo terms

Charge fluctuations of the strange metal in space and time
The strange metal is an enigma within the field of many-body quantum physics, as it defies the standard Fermi liquid theory of metals due to the absence of well-defined, electron-like quasiparticles. It has been presumed that strange metal behavior arises due to strong correlations between …

Inelastic X-ray scattering studies of broken symmetry in BSCCO
… at room temperature for all materials in the 'strange metal' state above the pseudogap, but are enhanced, particularly around the period four intercell ordering wavevector, as the system is cooled into the pseudogap state. In-plane acoustic phonons are a probe of the electron physics localized …

New features in the phase diagrams of the cuprate high-Tc superconductors mapped using strong magnetic fields
… line at critical hole-doping that bisects the strange metal regime and is accompanied by an abrupt change in the cotangent of the Hall angle. While the origin of the vertical boundary line remains to be ascertained, it appears distinct from the widely reported T* line and charge order, and …

Interplay between Correlation and Topology in Two-dimensional Systems
… such as unconventional superconductivity, strange metal behavior, exciton condensation, emergent Kondo lattice physics, quantum Hall ferromagnetism, (fractional) quantum anomalous Hall effect, and formation of anomalous Hall crystals. Typically in many of these systems, there is a nearly …

Superconductivity in the proximity of a quantum critical point
… fluid which deviates strongly from typical metallic behaviour; unconventional superconductivity can be induced by the strange metal region surrounding the zero-temperature phase transition. In this thesis we focus on three systems which demonstrate a highly tunable phase transition, with the …

Graphene-Based Nanodevices in the Superconducting and Strongly Correlated Regimes
… 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 nano-optics …

Slave particle study of the strongly correlated electrons
… arcs) instead of a closed Fermi surface, or the strange metal phase where the Fermi liquid theory breaks down and exhibits very unusual transport properties. The isotope effect in these materials is also very different from that of conventional superconductors. In the second part of this thesis …

Proximity effects and vortex dynamics in mesoscopic superconductor-normal metal-superconductor arrays
… electron transport. In other words, there are no metallic states at T = 0 in 1D and 2D systems. Although this theory has accurately described the low-temperature behavior of many materials, systems ranging from 2D semiconductors to disordered superconductors have in fact shown evidence of a …

Ultrafast Terahertz Spectroscopy for the Manipulation and Elucidation of Correlated Quantum Materials
… physics. For example, the charge carriers in a metallic (or photoexcited) material have a strong spectral weight here and many of the collective modes of insulating phases, such as phonons or magnons, occur at these energies as well. Specifically, the collective modes of two van der Waals …

Aspects of spin-charge separation in high Tc cuprates
… the point of view of the conventional theory of metals, i.e. the Fermi liquid theory. These include the high Tc itself, the linear resistivity in optimally doped cuprates, the "spin gap" phenomena, and antiferromagnetic fluctuations. Some of the basic features of the high Tc, phase diagram can be …

High pressure studies of superconductivity and anomalous normal states in novel quantum materials
… a novel incommensurate host-guest structure, strange metal, low-dimensional system, iron-based superconductivity, and a geometrically frustrated magnetic system. We used pressure as the primary tool in our studies, not only as one of the tuning parameters for accessing or tuning away from the …
