Theoretical Foundation & Governing Principles

Quantum device physics, a branch of quantum mechanics and solid-state physics, hinges on fundamental principles derived from the Schrödinger equation and the Pauli exclusion principle. At the core of quantum device physics are the quantum mechanical laws governing the behavior of particles at the atomic scale, which fundamentally differ from classical physics. The Schrödinger equation is a partial differential equation that describes how the quantum state of a physical system changes with time. It is given by: \[ i\$\hbar$ \frac{\partial}{\partial t} \Psi(\mathbf{r},t) = \hat{H} \Psi(\mathbf{r},t) \] where \( i \) is the imaginary unit, \( \$\hbar$ \) is the reduced Planck's constant, \( \Psi(\mathbf{r},t) \) represents the quantum state function, and \( \hat{H} \) denotes the Hamiltonian operator. The Hamiltonian encapsulates all the energy terms of the system, including kinetic and potential energies. The Pauli exclusion principle, a cornerstone of quantum mechanics, stipulates that no two fermions (particles with half-integer spin) can occupy the same quantum state simultaneously within a quantum system. This principle is crucial for understanding the electronic structure of materials and the behavior of electrons in quantum devices. In the context of quantum device physics, the Pauli exclusion principle governs the occupancy of electron states in solids, influencing the charge transport properties. Mathematically, the Schrödinger equation can be solved to find eigenstates and eigenvalues, which correspond to the allowed energy levels and the corresponding wave functions. These solutions provide the theoretical framework for predicting the behavior of electrons within a quantum device, enabling the design and simulation of novel devices such as quantum dots, spintronic devices, and topological insulators. In the case of Elsebeth Schröder's research group, these fundamental principles
