Bound States and Field-Polarized Haldane Modes in a Quantum Spin Ladder.
The challenge of one-dimensional systems is to understand their physics beyond the level of known elementary excitations. By high-resolution neutron spectroscopy in a quantum spin-ladder material, we probe the leading multiparticle excitation by characterizing the two-magnon bound state at zero field. By applying high magnetic fields, we create and select the singlet (longitudinal) and triplet ...
متن کاملTwo-Black-Hole Bound States
The quantum mechanics of N slowly-moving BPS black holes in five dimensions is considered. A divergent continuum of states describing arbitrarily closely bound black holes with arbitrarily small excitation energies is found. A superconformal structure appears at low energies and can be used to define an index counting the weighted number of supersymmetric bound states. It is shown that the inde...
متن کاملBound states and glueballs in three-dimensional Ising systems
We study the spectrum of massive excitations in three-dimensional models belonging to the Ising universality class. By solving the BetheSalpeter equation for 3D φ theory in the broken symmetry phase we show that recently found non-perturbative states can be interpreted as bound states of the fundamental excitation. We show that duality predicts an exact correspondence between the spectra of the...
متن کاملNonrelativistic Bound States in Quantum Field Theory∗
Nonrelativistic bound states are studied using an effective field theory. Large logarithms in the effective theory can be summed using the velocity renormalization group. For QED, one can determine the structure of the leading and next-to-leading order series for the energy, and compute corrections up to order α ln α, which are relevant for the present comparison between theory and experiment. ...

~aP+rr@r = ~~rTorp (84) The mass m though invariant in a Lorentz transformation is not necessarily a constant of the motion, even if the density p of the particle is constant, since m includes the thermodynamic internal energy Lsee Eq. (34)7. Included in the Minkowski force is a term which predicts a force on a particle when it exists in a temperature gradient, a force associated with the entro...
