Ground State Theory of d-Pu
Correlation effects are important for making predictions in the d phase of Pu. Using a realistic treatment of the intra-atomic Coulomb correlations we address the long-standing problem of computing ground state properties. The equilibrium volume is obtained in good agreement with experiment when taking into account Hubbard U of the order 4 eV. For this U, the calculation predicts a 5f5 atomicli...
متن کاملTowards a theory of Ground state uniqueness
We study groundstates in a generalization of Edwards-Anderson Ising model. We develop abstract discreate mathematical theory of incongruency called XOR-system.

متن کاملMultireference perturbation theory can predict a false ground state.
Prediction of a false ground state with popular variants of multireference perturbation theory (CASPT2 and MRMP) is reported for a remarkably simple chemical system: the Sc(2) molecule.
متن کاملGround State EntanglementEnergetics
We consider the ground state of simple quantum systems coupled to an environment. In general the system is entangled with its environment. As a consequence, even at zero temperature, the energy of the system is not sharp: a projective measurement can find the system in an excited state. We show that energy fluctuation measurements at zero temperature provide entanglement information. For two-st...
