Abstract: Neutral atoms trapped in optical tweezer arrays have emerged as a promising platform for quantum simulation and quantum computation. The dynamic reconfigurability of optical tweezer traps enables a high degree of single atom control and the ability to generate large-scale defect-free atom arrays in many geometries.

Spin qubits housed in silicon quantum dots are rapidly emerging as a viable quantum computing platform. In recent years, there have been single- and two-qubit gate demonstrations, which showed high fidelities to the extent that implementing quantum error correction codes appears to be within reach.

A promising avenue for studying the origin and evolution of the universe is to measure the Cosmic Microwave Background (CMB), the thermal radiation remaining from the Big Bang after billions of years of expansion. Today, this remnant takes the form of an extraordinarily uniform thermal blackbody of ~2.7 K in temperature.

Over the last six years, the LIGO and Virgo gravitational wave detectors have revolutionized gravitational wave astronomy by discovering the first compact binary mergers. There is much to learn about how these systems form in nature, and these discoveries have allowed to start characterizing the astrophysical population of binary black holes....

Physics defined on real manifolds and equipped with locality has achieved many successes theoretically as well as in describing our universe. Nevertheless, from a mathematical point of view, it is not as privileged. This thesis explores the possibility of non-Archimedean and non-local physics by studying a range of discrete and continuous...

Real world phenomenon are inherently nonlinear and complex in a way that usually cannot be understood from first principle. Yet intelligence behaviors appear in biological systems, which are shaped by billions years of evolution, to solve natural challenges.

Phases of matter are splendid, and get more complicated from physical systems to biochemical systems. Simple physics principles are proposed to categorise various phases of matter. The phys- ical principles are often exemplified by simple idealised models. When they are applied to more complicated biochemical systems, some generalisations may...

This Dissertation concerns phases of matter with various ``subdimensional'' properties. We start with topologically ordered phases with subdimensional properties. This includes a discussion of fracton topologically ordered phases, resonating valence plaquette phases, and floating topological phases.
