Strongly correlated electronic systems are at the forefront of research in materials and condensed matter physics, because of their many exotic properties and potential applications. Cuprate high temperature superconductors are the quintessential strongly correlated materials, characterized by an unconventional superconducting phase, the mechanism of which is still unclear, and an equally enigmatic normal state with many poorly understood properties, such as intertwined orders, spectroscopic pseudogap, and strange metallicity. In this thesis, I will present theoretical studies on fluctuating intertwined orders by investigating the Hubbard model, which is the canonical model Hamiltonian for describing electron dynamics in cuprates. First, I discuss tendencies of electronic nematicity in the Hubbard model and compare it with electronic Raman scattering in cuprates. The results show an enhancement of electronic nematicity, consistent with experimental observations, and suggest the capability of the Hubbard model to capture ordering tendencies relevant in cuprates. Next, I discuss fluctuating charge- and spin-density waves in the Hubbard model. Calculations show that robust fluctuating charge and spin orders are present in a wide parameter regime in the strange metal phase, consistent with recent experiments. The results point to the importance of fluctuating orders to all electronic properties of cuprates, as opposed to just the pseudogap regime as previously believed. Finally, I summarize the findings presented in this thesis and briefly survey the outlook for theoretical studies on fluctuating intertwined orders relevant for cuprates.
