Structural Phase Stability and Electron-Phonon Coupling in Lithium

First-principles calculations of the free energy of several structural phases of Li are presented. The densityfunctional linear-response approach is used to calculate the volume-dependent phonon frequencies needed for computing the vibrational free energy within the quasiharmonic approximation. We show that the transformation from a close-packed structure at low temperatures to the bcc phase up...

Electron—phonon Coupling and the Superconducting Phase Diagram of the LaAlO3—SrTiO3 Interface

The superconductor at the LaAlO3-SrTiO3 interface provides a model system for the study of two-dimensional superconductivity in the dilute carrier density limit. Here we experimentally address the pairing mechanism in this superconductor. We extract the electron-phonon spectral function from tunneling spectra and conclude, without ruling out contributions of further pairing channels, that elect...

Strong coupling lattice study of 1/g2 evolution in phase diagram and baryon mass

We investigate the phase diagram and the baryon mass (MB) in the color SU(Nc = 3) strong coupling lattice QCD with one species of staggered fermions at finite quark chemical potential (μ) and/or finite temperature (T ). In particular, their evolution with the finite coupling (1/g2) is studied in the next to leading order of the strong coupling expansion. We formulate the treatment of the tempor...

Sensitivity of the magnetic state of a spin lattice on itinerant electron orbital phase

Spatially extended localized spins can interact via indirect exchange interaction through Friedel oscillations in the Fermi sea. In arrays of localized spins such interaction can lead to a magnetically ordered phase. Without external magnetic field such a phase is well understood via a ”two-impurity” Kondo model. Here we employ non-equilibrium transport spectroscopy to investigate the role of t...

The phase diagram of twisted mass lattice QCD

We use the effective chiral Lagrangian to analyze the phase diagram of two-flavor twisted mass lattice QCD as a function of the normal and twisted masses, generalizing previous work for the untwisted theory. We first determine the chiral Lagrangian including discretization effects up to next-to-leading order (NLO) in a combined expansion in which m2π/(4πfπ) 2 ∼ aΛ (a being the lattice spacing, ...
