Orthogonality Catastrophe in Metals

Donald R. Hamann

Published Apr 26, 1971• 34 citations
Publisher

Abstract

The overlap of the ground states of a many-fermion system in the absence and presence of a localized potential is recalculated using a method introduced by Rivier and Simanek. Contrary to their claim, the result previously obtained by other methods is recovered.

Exact Calculation of the Orthogonality Catastrophe in Metals

N. Rivier, Eugen Šimánek

We give exact calculation, using the linked-cluster theorem, of the overlap between the ground-state wave functions of a system of $N$ fermions in the absence and in the presence of a localized potential. It is found that the overlap vanishes as ${N}^{\ensuremath{-}\ensuremath{\alpha}}$, where $\ensuremath{\alpha}(\ensuremath{\delta})$ contains both a nonperiodic and a $\ensuremath{\pi}$-periodic term in the phase shift $\ensuremath{\delta}({\ensuremath{\epsilon}}_{\mathrm{F}})$ due to the potential. The present result reduces to that of Anderson and of Nozi\`eres and de Dominicis for small phase shifts.

Orthogonality Catastrophe for a System of Interacting Electrons

Kei Yamada, Kei Yosida

The Anderson theorem concerning the overlap integral between two ground-state wave-functions of the electron system with different local potentials is discussed from a general point of view. It is shown that this theorem generally holds in the case where the initial Hamiltonian also includes electron interactions.

Orthogonality Catastrophe Due to Local Electron Interaction

Fusayoshi J. Ohkawa

The orthogonality theorem is proved in the Anderson Hamiltonian by persuing the time development of the overlap integrals. The overlap integrals are expressed in terms of the phase shift which takes into account local Coulomb repulsion between d-electrons as well as one body potential.

Orthogonality Catastrophe for a System of Interacting Electrons. II

K. Yamada, Kei Yosida

It is shown that the overlap integral between two ground-state wave functions for the Hamiltonian of the interacting electron system with different local potentials can be written generally in terms of the S-matrix describing potential scattering. Here, the local potential is considered to be a general inseparable one and the Green functions and self-energies are treated as operaors with off-diagonal elements. This orthogonality theorem expressed in a general form is applied to some special cases.

Exponential orthogonality catastrophe in single-particle and many-body localized systems

Dong‐Ling Deng, J. H. Pixley, Xiaopeng Li +1 more

We investigate the statistical orthogonality catastrophe (STOC) in single-particle and many-body localized systems by studying the response of the many-body ground state to a local quench. Using scaling arguments and exact numerical calculations, we establish that the STOC gives rise to a wave function overlap between the pre- and postquench ground states that has an exponential decay with the system size, in sharp contrast to the well-known power law Anderson orthogonality catastrophe in metallic systems. This exponential decay arises from a statistical charge transfer process where a particle can be effectively ``transported'' to an arbitrary lattice site. In a many-body localized phase, this nonlocal transport and the associated exponential STOC phenomenon persist in the presence of interactions. We study the possible experimental consequences of the exponential STOC on the Loschmidt echo and spectral function, establishing that this phenomenon might be observable in cold atomic experiments through Ramsey interference and radio-frequency spectroscopy.
