In Raman scatering, pump photons that are incident on a material are able to emit or absorb materials' excitations such as phonons and orbital transitions. This process generates red-shifted (Stokes) and blue-shifted (antiStokes) photons that are usually uncorrelated with each other. When real or virtual excitations emitted by a Stokes photon are coherently absorbed by another pump photon, an entangled Stokes-antiStokes photon pair is created, in a process analogous to the formation of Cooper pairs in superconductors [1].

Abstract: The objective of this thesis was to establish techniques for predicting and modelling moist desquamation (MD). The work in this thesis is based on the clinical studies of the novel Carbon Fibre Adjustable Reusable Accessory (CARA) breast support device. The epidermal dose measurements, treatment plans, and skin assessments from clinical studies of the CARA device were used to develop models to be applied during treatment planning to reduce the occurrence of MD in breast radiotherapy.

In this thesis, we study a class of non-topological solitons known as "Q-balls" which arise in complex scalar field theories with U(1) symmetry. We focus on the case where the U(1) symmetry is gauged and the theory admits a coupling to electromagnetism; the corresponding solitons are known as "gauged Q-balls". Using numerical simulations, we examine the dynamical behaviour of these objects in various scenarios. First, we investigate the classical stability of gauged Q-balls under assumptions of axial symmetry.

To understand astronomical objects and their environments, it is essential to study their behavior across time, energy and space. For compact objects, these analyses provide a unique window into physics in extreme environments, probing transient behavior, accretion processes, and tests of spacetime and gravity in the high field regime. In this thesis, I present novel approaches to revolutionize timing and spectral analysis and imaging with polarimetry in astronomy.

Amorphous solids are a diverse class of materials that have significant interest owing to their ubiquity in industry, yet a unifying theory to describe their mechanical response to load under temperature is lacking. Using a combination of highly parallelized numerical routines to simulate an elastoplastic model (EPM) of amorphous solids, as well the corresponding mean-field theory, I develop a scaling theory for the yielding of amorphous solids for non-zero temperature and driving rates.

Abstract:
The existence of dark matter has been inferred through many astrophysical evidences. However, much about its nature is unknown to this day. The several decades-long search for dark matter has given rise to many experiments and even more dark matter candidates. SuperCDMS is a direct detection experiment which uses cryogenic detectors to probe interactions of dark matter particles with Standard Model particles.

Abstract:
With the recent progress in high-order harmonic generation (HHG) using femtosecond lasers, laboratory photoelectron spectroscopy with an ultrafast, widely tunable vacuum-ultraviolet light source has become available. Whereas HHG-based photoemission experiments at kilohertz repetition rates have been severely limited by the space-charge effects in the past, the new development of compact HHG light sources with megahertz repetition rates allows for efficient photoemission and double photoemission experiments as is demonstrated here [1-7].

Abstract: We present a model of quantum cosmology based on anti-de Sitter/conformal field theory (AdS/CFT) holography. The spacetimes in our construction are time-symmetric, big-bang/big-crunch cosmologies with a negative cosmological constant $\Lambda$. In the simplest version of our model the cosmology lives inside a spatially finite bubble within an otherwise empty AdS spacetime. By studying the thermodynamic and geometric properties of this spacetime, we provide evidence that the ``bubble of cosmology'' spacetime has a well-defined dual CFT description.

Abstract: Crystalline graphene multilayers present a rich playground to explore correlated electronic phenomena in a tunable and ultra-clean setting. For instance, Bernal bilayer graphene and rhombohedral trilayer graphene host multiple symmetry-broken metallic phases at low temperature, as well as unconventional superconductors with different pairing symmetries.

"Exotic weak decays offer a unique way to probe physics beyond the Standard Model in a low-energy regime using the atomic nucleus as a window to complement the high-energy searches done at particle accelerator facilities. However, in order to extract the relevant physics parameters from experimental observations, inputs from nuclear theory are required.

[abstract] Quasiprobability representations serve as a bridge between classical and quantum descriptions of physical systems. In these representations, nonnegativity allows for a probabilistic interpretation, aligning the description with classical physics.

Abstract:
Rhombohedral(R)-stacked TMD means the neighbouring layers are oriented in the same direction, which can be obtained through either chemical synthesis or artificial stack with a small twist. The investigation into how the stacking order determines the properties of TMD homobilayers is crucial for understanding the exotic physics observed in two-dimensional semiconductors.

Abstract: By quenching the interaction strength, we induce and study a topological dynamical phase transition between superconducting phases of a planar fermionic model. Using the Lindblad Master Equation approach to account for the interactions of Bogoliubov quasiparticles among themselves and with the fluctuations of the superconducting order parameter, we derive the corresponding relaxation dynamics of the order parameter. To fully characterize the phase transition, we also compute the fidelity and the spin-Hall conductance of the system.

Abstract:
The search for the Higgs boson was central to the conception and design of the LHC detectors. However, measurements of the Higgs coupling to the second and third-generation quarks were regarded as extremely challenging and, in some cases, impossible. Scientific ingenuity and original thought have allowed ATLAS and CMS to probe the coupling of the Higgs boson to quarks. I will discuss techniques (including machine learning) used to achieve this and provide a brief perspective on future directions.
