Magnetic ground state of FeSe [PDF]
Nature Communications, 2016 Elucidating the nature of the magnetism of a high-temperature superconductor is crucial for establishing its pairing mechanism. The parent compounds of the cuprate and iron-pnictide superconductors exhibit N\'eel and stripe magnetic order, respectively ...

Multielectron Ground State Electroluminescence
Physical Review Letters, 2019 The ground state of a cavity-electron system in the ultrastrong coupling regime is characterized by the presence of virtual photons. If an electric current flows through this system, the modulation of the light-matter coupling induced by this non ...

The ground state of the Kondo insulator. [PDF]
Sci Rep, 2023 AbstractThe Kondo insulator (KI) is the state of an electron liquid in the Kondo lattice at half filling, studied within the mean field approach. We demonstrate, that the $${Z}_2$$ Z 2 -field, which is formed by interaction between electrons and local moments,

Atomic Ground-State Energies [PDF]
Canadian Journal of Physics, 1980 It is demonstrated that atomic Hartree–Fock binding energies may be reproduced with great accuracy (within about four parts in a thousand) by a scaled model system in which the electrons are noninteracting, and are bound in a bare Coulomb potential.

Mimicking Time Evolution within a Quantum Ground State: Ground-State Quantum Computation, Cloning, and Teleportation [PDF]
, 2003 Ground-state quantum computers mimic quantum mechanical time evolution within the amplitudes of a time-independent quantum state. We explore the principles that constrain this mimicking. A no-cloning argument is found to impose strong restrictions. It is shown, however, that there is flexibility that can be exploited using quantum teleportation methods

Ground State Entanglement Energetics
Physica E: Low-dimensional Systems and Nanostructures, 2005 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 ...

Entanglement Energetics in the Ground State [PDF]
Journal of Modern Optics, 2004 We show how many-body ground state entanglement information may be extracted from sub-system energy measurements at zero temperature. A precise relation between entanglement and energy fluctuations is demonstrated in the weak coupling limit. Examples are

EPL (Europhysics Letters), 2012 Designing and optimizing cost functions and energy landscapes is a problem encountered in many fields of science and engineering. These landscapes and cost functions can be embedded and annealed in experimentally controllable spin Hamiltonians.

Ground state at high density [PDF]
Communications in Mathematical Physics, 2011 Weak limits as the density tends to infinity of classical ground states of integrable pair potentials are shown to minimize the mean-field energy functional.
