(2013-07-16)6d (2, 0) theory on M5 branes is investigated by considering its KK modes on a 2d space. Selecting KK modes on different 2d spaces amounts to choosing different set of selfdual strings as the perturbative degrees of freedom ...
-
(2023-07-12)The study of exoplanet atmospheres has become a rapidly expanding field within astronomy. However, most observations are currently conducted using space-based observatories. In this dissertation, we introduce a groundbreaking ...
-
(2019-11-04)Collisions of nuclei at large energies create fireballs of hot hadronic matter and quark gluon plasma. The properties of these extreme forms of nuclear matter can be studied by the experiments at the Relativistic Heavy Ion ...
-
(2021-08-18)Since the Bose-Einstein condensation (BEC) of magnons in ferromagnetic films was realized, it has drawn much attention due to the unique property of magnon spectrum. Namely, the BEC has two components corresponding to the ...
-
(2010-10-12)Genetic algorithm is often used to find the global optimum in a multi-dimensional search problem. Inspired by the natural evolution process, this algorithm employs three reproduction strategies -- cloning, crossover and ...
-

(2020-04-10)Tip-enhanced Raman scattering (TERS) and tip-enhanced photoluminescence (TEPL) can be widely applied to multi-disciplinary studies involving near-field scanning technologies. Several types of TERS setups have been applied ...
-
(2019-07-09)The ^22Ne(α,n) reaction is an important neutron source reaction for the slow neutron capture process (s-process) in asymptotic giant branch stars. Direct measurements are extremely difficult to carry out at Gamow energies ...
-
(2011-08-08)Localized detection of very small regularly placed magnetic systems, such as an array of tiny magnetic islands, has been of great interest to scientists for years because of their applications to data storage media. One ...
-
(2018-05-07)Introductory Physics (IP) forms part of the foundational knowledge necessary to success in an undergraduate engineering degree. Here, the impact of IP is studied to address three research questions: 1) What is the correlation ...
-
(2016-12-06)Integrating cavities have been used in radiometric and photometric measurements since their creation by Frederick Ulbricht in 1900. Modern commercial integrating cavities use Spectralon, a PTFE-based diffuse reflector with ...
-
(2012-10-19)Irreversible thermodynamics is a widely-applicable toolset that extends thermodynamics to describe systems undergoing irreversible processes. It is particularly useful for describing macroscopic flow of system components, ...
-
(2019-04-17)The interaction of light with biological media represents an increasingly important area of research. Recent expansion of ultrafast laser sources in the midinfrared (MIR) regime is driving research in previously unexplored ...
-
(2017-04-27)There are many methods to achieve optical gain for laser applications; such methods have been used to make improved spectroscopy and microscopy apparatus. In particular, gain from acoustic and atomic interactions has ...
-
(2015-08-05)The main subjects of this dissertation are spin glass applications in other disciplines and spin glass algorithms. Spin glasses are magnetic systems with disorder and frustration, and the essential physics of spin glasses ...
-
(2017-07-24)This work presents two searches for dark matter at the Large Hadron Collider (LHC). The first is focused on decays of the supersymmetric partner of the top quark, the stop quark (t). By exploiting vector boson fusion (VBF) ...
