WebOne of the most outstanding challenges in the experimental study of quantum many-body dynamics is the difficulty of realizing systems with a desired Hamiltonian. Also, even if … The many-body problem is a general name for a vast category of physical problems pertaining to the properties of microscopic systems made of many interacting particles. Microscopic here implies that quantum mechanics has to be used to provide an accurate description of the system. Many can be anywhere from three to infinity (in the case of a practically infinite, homogeneous or periodic system, such as a crystal), although three- and four-body systems can be treated by sp…

WebAbstract. We define the “BEC state” to be the many-body wavefunction where all particles are in the same one-body state. Using an argument analogous to Anderson’s Orthogonality Catastrophe, we argue that for interacting particles the amplitude of the BEC state within the many-body wavefunction goes to zero in the thermodynamic limit. WebThe CADD approach has been applied to various successful drugs, some of which are in use in the market. Examples include imatinib 28 and nilotinib. 29 Several other targets include ER, 30,31 EGFR, 32,33 PKCβ 2, 34 and BCR-Abl. 35 A biomolecular system can be simulated using molecular mechanics (MM), QM, or a hybrid method (QM/MM), …

WebThat this condition is also sufficient is a much more delicate issue which largely depends on the physical hypotheses you assume on realizable pure states. In principle all vectors $\psi \in L^2(\mathbb{R}^3,d^3x)$ are admitted. No continuity or differentiability requirements make sense, even if it is sometimes erroneously stated.
