Exact Ground State Energy of the Strong-Coupling Polaron
The polaron has been of interest in condensed matter theory and field theory for about half a century, especially the limit of large coupling constant, α. It was not until 1983, however, that a proof of the asymptotic formula for the ground state energy was finally given by using difficult arguments involving the large deviation theory of path integrals. Here we derive the same asymptotic resul...
متن کاملResonances of the helium atom in a strong magnetic field
We present an investigation on the resonances of a doubly excited helium atom in a strong magnetic field covering the regime B = 0 − 100 a.u. A full-interaction approach which is based on an anisotropic Gaussian basis set of one-particle functions being nonlinearly optimized for each field strength is employed. Accurate results for a total of 17 resonances below the threshold of consisting of H...
متن کاملThe Ground State of Monolayer Graphene in a Strong Magnetic Field
Experiments indicate that the ground state of graphene in a strong magnetic field exhibits spontaneous breaking of SU(4) symmetry. However, the nature of the corresponding emergent state is unclear because existing theoretical methods approximate the broken-symmetry solutions, yielding nearly-degenerate candidate ground states having different emergent orders. Resolving this ambiguity in the na...
متن کاملRelativistic hydrogenic atoms in strong magnetic fields
In the Dirac operator framework we characterize and estimate the ground state energy of relativistic hydrogenic atoms in a constant magnetic field and describe the asymptotic regime corresponding to a large field strength using relativistic Landau levels. We also define and estimate a critical magnetic field beyond which stability is lost.
متن کاملHydrogen atom moving across a strong magnetic field: analytical approximations
Analytical approximations are constructed for binding energies, quantum-mechanical sizes and oscillator strengths of main radiative transitions of hydrogen atoms arbitrarily moving in magnetic fields ∼ 1012–1013 G. Examples of using the obtained approximations for determination of maximum transverse velocity of an atom and for the evaluation of absorption spectra in magnetic neutron-star atmosp...
