Electron spectral function in two-dimensional fractionalized phases
We study the electron spectral function of various zero-temperature spin-charge separated phases in two dimensions. In these phases, the electron is not a fundamental excitation of the system, but rather ‘‘decays’’ into a spin-1/2 chargeless fermion ~the spinon! and a spinless charge e boson ~the chargon!. Using low-energy effective theories for the spinons ~d-wave pairing plus possible Néel or...
متن کاملElectron localization function for two-dimensional systems
The concept of the electron localization function ELF is extended to two-dimensional 2D electron systems. We show that the topological properties of the ELF in two dimensions are considerably simpler than in molecules studied previously. We compute the ELF and demonstrate its usefulness for various physical 2D systems focusing on semiconductor quantum dots that effectively correspond to a confi...
متن کاملMicroscopic models for fractionalized phases in strongly correlated systems
We construct explicit examples of microscopic models that stabilize a variety of fractionalized phases of strongly correlated systems in a spatial dimension larger than one, and in a zero external magnetic field. These include models of charge fractionalization in boson-only systems, and various kinds of spin-charge separation in electronic systems. We determine the excitation spectrum, and sho...
متن کاملElectron-electron interactions and two-dimensional-two-dimensional tunneling.
We derive and evaluate expressions for the dc tunneling conductance between interacting two-dimensional electron systems at non-zero temperature. The possibility of using the dependence of the tunneling conductance on voltage and temperature to determine the temperature-dependent electronelectron scattering rate at the Fermi energy is discussed. The finite electronic lifetime produced by electr...
متن کاملElectron-phonon coupling in a two-dimensional inhomogeneous electron gas: consequences for surface spectral properties
We investigate the coupling of an inhomogeneous electron system to phonons. The properties of an electronic system composed of a mixture of microscopic ordered and disordered islands are changed fundamentally by a phonon mode. In high-Tc cuprates, such a phase separation scenario is supported by recent STM and nuclear quadrupole resonance studies. We show that even a weak or moderate electronph...
