Renormalization-group improved resummation of super-leading logarithms

Journal of High Energy Physics
A new strategy is presented for systematically treating super-leading logarithmic contributions including higher-order Glauber exchanges for non-global LHC observables in renormalization-group (RG) improved perturbation theory.

Ralph Kenna’s Scaling Relations in Critical Phenomena

Entropy
In this note, we revisit the scaling relations among “hatted critical exponents”, which were first derived by Ralph Kenna, Des Johnston, and Wolfhard Janke, and we propose an alternative derivation for some of them. For the scaling relation involving the

Logarithmic corrections to scaling in turbulent thermal convection

, 2001
We use an analytic toy model of turbulent convection to show that most of the scaling regimes are spoiled by logarithmic corrections, in a way consistent with the most accurate experimental measurements available nowadays. This sets a need for the search

Critical behavior of the pure and random-bond two-dimensional triangular Ising ferromagnet

, 2010
We investigate the effects of quenched bond randomness on the critical properties of the two-dimensional ferromagnetic Ising model embedded in a triangular lattice.

On Compact Routing for the Internet

, 2007
While there exist compact routing schemes designed for grids, trees, and Internet-like topologies that offer routing tables of sizes that scale logarithmically with the network size, we demonstrate in this paper that in view of recent results in compact ...

Uplink Downlink Rate Balancing and throughput scaling in FDD Massive MIMO Systems

, 2015
In this work we extend the concept of uplink-downlink rate balancing to frequency division duplex (FDD) massive MIMO systems. We consider a base station with large number antennas serving many single antenna users.

Efficient Learning of Long-Range and Equivariant Quantum Systems [PDF]

Quantum
In this work, we consider a fundamental task in quantum many-body physics – finding and learning ground states of quantum Hamiltonians and their properties.

Logarithmic correlation functions in 2D critical percolation

Journal of High Energy Physics
It is believed that the large-scale geometric properties of two-dimensional critical percolation are described by a logarithmic conformal field theory, but it has been challenging to exhibit concrete examples of logarithmic singularities and to find an ...

Entanglement Entropy of Fermi Liquids via Multidimensional Bosonization

Physical Review X, 2012
The logarithmic violations of the area law, i.e., an “area law” with logarithmic correction of the form S∼L^{d-1}log⁡L, for entanglement entropy are found in both 1D gapless fermionic systems with Fermi points and high-dimensional free fermions.

The O(n) Model in the $n\to 0$ Limit (self-avoiding-walks) and Logarithmic Conformal Field Theory

, 2004
We consider the O(n) theory in the $n \to 0$ limit. We show that the theory is described by logarithmic conformal field theory, and that the correlation functions have logarithmic singularities.
