Applications of Gauge/Gravity Duality in Heavy Ion Collisions
(2014)In order to analyze the strongly interacting quark gluon plasma in heavy ion collisions, we study different probes by applying the gauge/gravity duality to facilitate our qualitative understandings on such a non-perturbative ... -
Aspects of the (0,2)-McKay Correspondence
(2015)We study first order deformations of the tangent sheaf of resolutions of Calabi-Yau threefolds that are of the form $\CC^3/\ZZ_r$, focusing on the cases where the orbifold has an isolated singularity. We prove a lower bound ... -
Effective Field Theory Studies of Few-nucleon Systems: Fundamental Symmetry Violation, Electromagnetic Interactions, and Direct Detection of Dark Matter
(2023)Effective field theory (EFT) has evolved as a powerful model-independent theoretical framework for illuminating complicated interactions across a wide range of physics areas and subfields. It takes advantage of the scale ... -
Eigenstate Entanglement Scaling and Quantum Simulation of Many-body Systems by Entanglement Renormalization
(2022)Quantum entanglement lies at the heart of modern physics and pervades various research fields. In the field of quantum many-body physics, celebrated area and log-area laws have been established for the entanglement entropy ... -
Fermion Mass Generation without Spontaneous Symmetry Breaking
(2016)The conventional mechanism of fermion mass generation in the Standard Model involves Spontaneous Symmetry Breaking (SSB). In this thesis, we study an alternate mechanism for the generation of fermion masses that does not ... -
Moduli Space of (0,2) Conformal Field Theories
(2016)In this thesis we study aspects of (0,2) superconformal field theories (SCFTs), which are suitable for compactification of the heterotic string. In the first part, we study a class of (2,2) SCFTs obtained by fibering ... -
Partonic Transport Model Application to Heavy Flavor
(2019)Heavy-flavor particles are excellent probes of the properties of the hot and dense nuclear medium created in the relativistic heavy-ion collisions. Heavy-flavor transport coefficients in the quark-gluon plasma (QGP) stage ... -
Probing Exotic Boundary Quantum Phases with Tunable Nanostructure
(2012)Boundary quantum phases ---a special type of quantum phenomena--- occur in the boundary part of the system. The boundary part can be a surface of a bulk material, an interface between two distinct system, and even it can ... -
Quantifying Gene Regulatory Networks
(2014)\abstractTranscription and translation describe the flow of genetic information from DNA to mRNA to protein. Recent studies show that at a single cell level, these processes are stochastic, which results in the variation ... -
Quantum Critical Phenomena of Relativistic Fermions in 1+1d and 2+1d
(2022)In this dissertation, we study the phase structures and the quantum critical phenomena of relativistic lattice fermions with $\O(2N_f)$ symmetry in one and two spatial dimensions, motivated by the ability to perform efficient ... -
Scalar Field Wave Dark Matter and Galactic Halos
(2021)The question of ``What is Dark Matter?" has been a focus of cosmological research since the turn of the 20th century. Though the composition of Dark Matter is unknown, the existence of Dark Matter is crucial to the modern ... -
Using Gaussian Processes for the Calibration and Exploration of Complex Computer Models
(2014)Cutting edge research problems require the use of complicated and computationally expensive computer models. I will present a practical overview of the design and analysis of computer experiments in high energy nuclear and ...
