Pseudoparticle-operator description of an interacting bosonic gas.
We write the Hamiltonian of the Bose gas with two-body repulsive δ-function potential in a pseudoparticle operator basis which diagonalizes the problem via the Bethe ansatz. In this operator basis the original bosonic interactions are represented by zero-momentum forward-scattering interactions between Landau-liquid pseudoparticles. We find that this pseudoparticle operator algebra is complete:...
متن کاملComplete Pseudoparticle Operator Representation for Integrable Electronic Luttinger Liquids
We introduce the pseudoparticle operator algebra that generates all Hubbardchain eigenstates from a single reference vacuum. The occurence of only zeromomentum pseudoparticle forward scattering at all energy scales combined with the infinite pseudoparticle-number conservation laws establish this operator basis as the most suitable for dealing with transport properties at finite frequencies. We ...
متن کاملBosonic integer quantum Hall effect in an interacting lattice model.
We study a bosonic model with correlated hopping on a honeycomb lattice, and show that its ground state is a bosonic integer quantum Hall (BIQH) phase, a prominent example of a symmetry-protected topological (SPT) phase. By using the infinite density matrix renormalization group method, we establish the existence of the BIQH phase by providing clear numerical evidence: (i) a quantized Hall cond...
متن کاملAn Operator-Like Description of Love Affairs
We adopt the so–called occupation number representation, originally used in quantum mechanics and recently considered in the description of stock markets, in the analysis of the dynamics of love relations. We start with a simple model, involving two actors (Alice and Bob): in the linear case we obtain periodic dynamics, whereas in the nonlinear regime either periodic or quasiperiodic solutions ...
متن کاملBosonic effective action for interacting fermions
We present a bosonic description for systems of interacting fermions. A systematic expansion of the free energy starts with a solution to the lowest order Schwinger-Dyson or gap equation. Part of the phase diagram for the Hubbard model is computed in this framework. We propose a two particle irreducible formulation of an exact renormalization group equation for computations beyond leading order...
