商品描述
This book provides an in-depth theoretical exploration of quantum transport and optical properties in nanodevices, focusing on quantum dots, topological superconducting nanowires, and graphene. It is designed for graduate students and researchers seeking to understand these systems and their implications for advancing nanophotonic and nanoelectronic technologies. Beginning with foundational concepts in quantum transport, the book covers key phenomena such as the Coulomb blockade, the Kondo effect, and the physics of Majorana fermions and Majorana bound states. A review of graphene's electronic properties and the optical characteristics of quantum dots is also included, establishing a basis for the more advanced topics that follow. The book explores a nanojunction model where a quantum dot is integrated into a semiconducting-superconducting heterostructure that hosts Majorana bound states. The study investigates Majorana-induced phonon-assisted quantum tunneling in topological superconducting nanowires under magnetic flux. This model offers valuable insights for future experiments aimed at detecting Majorana bound states, with implications for topological quantum computing. Additionally, the book explores quantum transport in a system where a semiconductor quantum dot is embedded between monolayer graphene leads. Applying an external magnetic field enables spin-polarized transport, providing an ideal platform for studying many-body quantum phenomena such as the Kondo effect. Using nonequilibrium Green's function formalism, this section highlights how graphene's electronic properties can drive next-generation nanoelectronic devices. Beyond transport, the book also examines the optical properties of quantum dots, focusing on their linear and nonlinear characteristics. Perturbation theory is employed to study absorption coefficients and refractive index changes in two-level quantum dot systems, with potential applications in optoelectronics and photonics. Throughout, complex mathematical treatments are presented in an accessible manner, ensuring that even readers with a foundational understanding of nanophysics can engage with the material. This book serves as a valuable resource for researchers and students working in the fields of nanophysics, nanoelectronics, and quantum device research. It deepens theoretical understanding of these systems but also offers practical insights into their experimental realization and technological potential.
商品描述(中文翻譯)
本書深入探討量子傳輸和納米裝置的光學特性，重點關注量子點、拓撲超導納米線和石墨烯。它旨在幫助研究生和研究人員理解這些系統及其對推進納米光子學和納米電子技術的影響。
本書從量子傳輸的基本概念開始，涵蓋了關鍵現象，如庫侖阻塞（Coulomb blockade）、康多效應（Kondo effect）以及馬約拉納費米子（Majorana fermions）和馬約拉納束縛態（Majorana bound states）的物理學。書中還回顧了石墨烯的電子特性和量子點的光學特徵，為後續更高級的主題奠定基礎。
本書探討了一個納米接合模型，其中量子點集成在一個承載馬約拉納束縛態的半導體-超導異質結構中。研究調查了在磁通下，拓撲超導納米線中馬約拉納引起的聲子輔助量子隧穿。這個模型為未來旨在檢測馬約拉納束縛態的實驗提供了寶貴的見解，並對拓撲量子計算具有重要意義。
此外，本書還探討了在單層石墨烯引線之間嵌入半導體量子點的系統中的量子傳輸。施加外部磁場使得自旋極化傳輸成為可能，提供了一個理想的平台來研究許多體量子現象，如康多效應。利用非平衡格林函數形式主義，本節強調了石墨烯的電子特性如何驅動下一代納米電子裝置。
除了傳輸外，本書還檢視了量子點的光學特性，重點關注其線性和非線性特徵。使用微擾理論研究兩能級量子點系統中的吸收係數和折射率變化，並探討其在光電和光子學中的潛在應用。
整體而言，複雜的數學處理以易於理解的方式呈現，確保即使是對納米物理有基本了解的讀者也能參與其中。本書是從事納米物理、納米電子學和量子裝置研究的研究人員和學生的重要資源。它不僅加深了對這些系統的理論理解，還提供了對其實驗實現和技術潛力的實用見解。
