Quantum Hall ice

Gia-Wei Chern, Armin Rahmani, Ivar Martin, and Cristian D. Batista

Phys. Rev. B 90, 241102(R) (2014) - Published 1 December, 2014

The authors study a model in which non-interacting itinerant electrons are coupled to Ising spins in kagome spin ice. They demonstrate that spin disorder leads to localization of itinerant electron states and to plateaus in the Hall conductance as a function of electron density.

Transport characteristics of a single C60-molecule junction revealed by multiple Andreev reflections

Ryoichi Hiraoka, Ryuichi Arafune, Noriyuki Tsukahara, Maki Kawai, and Noriaki Takagi

Phys. Rev. B 90, 241405(R) (2014) - Published 2 December, 2014

The I-V characteristics for atomic junction between two superconductors exhibit steps at voltages 2Δ/n (with n=1, 2, 3, …) associated with multiple Andreev reflections (MAR). These features have been used in the past to determine the fundamental transport characteristics of atomic junctions. In this work, the authors present a development of the MAR technique by utilizing a superconducting Nb STM tip as one of the leads to study the transport properties of C60 fullerene molecule. By analyzing the tunneling spectra and high-resolution molecular imaging, they were able to determine the number of conduction channels for C60 as well as the origin and the dependence of the transmission coefficients on the contact geometry.

Conformal field theories at nonzero temperature: Operator product expansions, Monte Carlo, and holography

Emanuel Katz, Subir Sachdev, Erik S. Sørensen, and William Witczak-Krempa

Phys. Rev. B 90, 245109 (2014) - Published 1 December, 2014

Strongly correlated quantum critical points with conformal symmetry in two spatial dimensions describe many phase transitions in condensed matter systems, as for example that from superfluid to insulator. Combining field theory methods, Monte Carlo simulations, and the holographic duality from string theory, the authors use an operator product expansion to derive non-perturbative results for these systems, including the leading terms in the frequency dependence of the nonzero temperature conductivity and sum rules obeyed by the conductivity. These methods and results are applicable to a wide class of conformal field theories for condensed matter systems.

Energy density of variational states

Leon Balents

Phys. Rev. B 90, 245116 (2014) - Published 8 December, 2014

For a given many-body Hamiltonian, can a wavefunction in the wrong phase yield an arbitrarily good variational approximation to the true ground state energy density? The author discusses systems for which the answer is positive and outlines other cases where the Hamiltonian is expected to be variationally robust.

Möbius molecules and fragile Mott insulators

Lukas Muechler, Joseph Maciejko, Titus Neupert, and Roberto Car

Phys. Rev. B 90, 245142 (2014) - Published 23 December, 2014

Strongly correlated fermionic systems have been one of the most studied fields in condensed matter theory. The competition between Coulomb-repulsion and kinetic energy leads to a manifold of individual phases, especially in lower dimensions. Famous examples are Luttinger liquids in one dimensions, Mott-insulators or topological phases such as spin liquids. Recently a new class of non-trivial insulators has been introduced, the fragile Mott insulator (FMI). In this paper the authors extend the concept of an FMI to the case of ring-shaped molecules and study the interplay between symmetry, strong correlations as well as strong interactions which ultimately determine the electronic structure of the system.

YbN: An intrinsic semiconductor with antiferromagnetic exchange

H. Warring, B. J. Ruck, J. F. McNulty, E.-M. Anton, S. Granville, A. Koo, B. Cowie, and H. J. Trodahl

Phys. Rev. B 90, 245206 (2014) - Published 29 December, 2014

Using modern thin film growth techniques, and performing structural, magnetic, optical and electrical transport measurements on YbN thin films, the authors show that these films are antiferromagnetic and semiconducting, unlike other rare-earth nitrides that are either para- or ferromagnetic.

Three- to two-dimensional crossover in time-dependent density-functional theory

Shahrzad Karimi and Carsten A. Ullrich

Phys. Rev. B 90, 245304 (2014) - Published 22 December, 2014

How well the various approximate exchange-correlation functionals in density functional theory capture the 3D to 2D crossover, observed, for example, for plasmon modes in quantum wells that approach the strictly two-dimensional limit? This work, inspired by several ground-state DFT studies performed a few years ago, examines this question in the dynamical case, using time-dependent DFT, and reveals that the (semi)local 3D exchange eventually breaks down, but remains valid for most practical applications. Also, it demonstrates that nonlocal, orbital-dependent functionals are the appropriate way to handle the dimensional crossover.

Using modern thin film growth techniques, and performing structural, magnetic, optical and electrical transport measurements on YbN thin films, the authors show that these films are antiferromagnetic and semiconducting, unlike other rare-earth nitrides that are either para- or ferromagnetic.

Phys. Rev. B 90, 245304 (2014) - Published 22 December, 2014

How well the various approximate exchange-correlation functionals in density functional theory capture the 3D to 2D crossover, observed, for example, for plasmon modes in quantum wells that approach the strictly two-dimensional limit? This work, inspired by several ground-state DFT studies performed a few years ago, examines this question in the dynamical case, using time-dependent DFT, and reveals that the (semi)local 3D exchange eventually breaks down, but remains valid for most practical applications. Also, it demonstrates that nonlocal, orbital-dependent functionals are the appropriate way to handle the dimensional crossover.
