Effects of boson dispersion in fermion-boson coupled systems
We study the nonlinear feedback in a fermion-boson system using an extension of dynamical mean-field theory and the quantum Monte Carlo method. In the perturbative regimes ~weak-coupling and atomic limits! the effective interaction among fermions increases as the width of the boson dispersion increases. In the strong-coupling regime away from the antiadiabatic limit, the effective interaction d...
متن کاملFluctuation Effects by Boson Dispersion in Fermion-boson Coupled Systems
Nonlinear feedback effects due to dispersive bosons are studied in fermion-boson coupled systems by using an extension of dynamical mean-field theory. In the nonperturbative regime, strong coupling and nonadiabaticity reduce effective interaction between fermions as the width of boson dispersion increases. The boson field is completely softened at the crossover to this regime. The softening is ...
متن کاملUltracold superstrings in atomic boson-fermion mixtures.
We propose a setup with ultracold atomic gases that can be used to make a nonrelativistic superstring in four spacetime dimensions. In particular, we consider for the creation of the superstring a fermionic atomic gas that is trapped in the core of a vortex in a Bose-Einstein condensate. We explain the required tuning of experimental parameters to achieve supersymmetry between the fermionic ato...
متن کاملCP violation in fermion pair decays of neutral boson particles.
We study CP violation in fermion pair decays of neutral boson particles with spin 0 or 1. We study a new asymmetry to measure CP violation in η,KL → μ+μ− decays and discuss the possibility of measuring it experimentally. For the spin-1 particles case, we study CP violation in the decays of J/ψ to SU(3) octet baryon pairs. We show that these decays can be used to put stringent constraints on the...
متن کاملBoson-fermion Dyson mapping and supersymmetry in fermion systems
We demonstrate that exact supersymmetry can emerge in a purely fermionic system. This “supersymmetry without bosons” is unveiled by constructing a novel boson-fermion Dyson mapping from a fermion space to a space comprised of collective bosons and ideal fermions. In a nuclear structure context the collective spectra of even and odd nuclei can then be unified in a supersymmetric description with...
