Short-time-evolved wave functions for solving quantum many-body problems
The exact ground state of a strongly interacting quantum many-body system can be obtained by evolving a trial state with finite overlap with the ground state to infinite imaginary time. In many cases, since the convergence is exponential, the system converges essentially to the exact ground state in a relatively short time. Thus a short-time evolved wave function can be an excellent approximati...
متن کاملUniversitet Analytic structure of many - body Coulombic wave functions
We investigate the analytic structure of solutions of non-relativistic Schrödinger equations describing Coulombic manyparticle systems. We prove the following: Let ψ(x) with x = (x1, . . . , xN ) ∈ R denote an N -electron wavefunction of such a system with one nucleus fixed at the origin. Then in a neighbourhood of a coalescence point, for which x1 = 0 and the other electron coordinates do not ...
متن کاملConvexity and the quantum many-body problem
We recall some properties of convex functions and, in particular, of the sum of the largest eigenvalues of a Hermitian matrix. From these properties a new estimate of an arbitrary eigenvalue of a sum of Hermitian matrices is derived, which in turn is used to compute an approximate associated spectral projector. These estimates are applied for the first time to explain generic spectral features ...
متن کاملMeasuring entanglement entropies in many-body systems
We explore the relation between entanglement entropy of quantum many-body systems and the distribution of corresponding, properly selected, observables. Such a relation is necessary to actually measure the entanglement entropy. We show that, in general, the Shannon entropy of the probability distribution of certain symmetry observables gives a lower bound to the entropy. In some cases this boun...
متن کاملMeasuring the quantum mechanical wave function
In the past few years experimenters have learned how to determine the complete quantum state of an ensemble of particles or ® elds which have been prepared according to some unknown procedure. Through these experiments they have answered a question posed by W. Pauli in the 1930s. The methods used involve measuring statistical distributions of a well chosen set of physical observables and using ...
