- 요약Quantum Chromodynamics (QCD) is the modern theory of strong nuclear interaction. Its intricate topological phenomena, spanning from the vacuum to excited states, especially baryons, provide unique insights into the dynamics of high-energy scattering processes involving protons or heavy ions. Similar phenomena can be identified and explored in lower-dimensional theories used as toy models of QCD.In this dissertation, we first investigate the topological structure across various energy scales in baryon states. The topological structure of gluon distribution is expected to influence the spin decomposition at the partonic level, a cornerstone of the future Electron-Ion Collider (EIC) experimental program. In this dissertation we explore an analog of such a structure in 1+1 dimensional QCD in an exactly solvable limit and identify the signatures of topology in constituents carrying a small momentum fraction. Moreover, the topological configuration of a junction of color strings connecting the valence quarks is believed to transport the baryon number in high-energy hadron-hadron collisions. We study the implications of this concept for electron-proton collisions and obtain refined predictions for rapidity distributions of produced baryons, accounting for correlations between fragmenting strings. The topology of the QCD vacuum is expected to manifest in local event-by-event CP violation in heavy ion collisions, leading to anomalous transport effects like the chiral magnetic effect (CME). We suggest a novel baryon number-electric charge correlator in which the anomalous transport contribution scales linearly with the net baryon number at midrapidity. This property offers a means to isolate the CME contribution from the background, facilitating the detection of the CME in heavy ion collisions.Finally, we address the question of quantum entanglement between the fragmenting jets in the context of 1+1-dimensional quantum electrodynamics. Using quantum simulations on classical hardware, we observe steady entanglement entropy generation and identify the degrees of freedom responsible for it. We notice that they transition from fermionic Fock states to meson-like bound states during jet fragmentation, thus representing a direct analog of hadronization in real time.
