Causality & Holographic Entanglement Entropy (2014)
Journal Article
Headrick, M., Hubeny, V. E., Lawrence, A., & Rangamani, M. (2014). Causality & Holographic Entanglement Entropy. Journal of High Energy Physics, 2014(12), Article 162. https://doi.org/10.1007/jhep12%282014%29162

We identify conditions for the entanglement entropy as a function of spatial region to be compatible with causality in an arbitrary relativistic quantum field theory. We then prove that the covariant holographic entanglement entropy prescription (whi... Read More about Causality & Holographic Entanglement Entropy.

Physics of F-theory compactifications without section (2014)
Journal Article
Anderson, L. B., García-Etxebarria, I., Grimm, T. W., & Keitel, J. (2014). Physics of F-theory compactifications without section. Journal of High Energy Physics, 2014(12), Article 156. https://doi.org/10.1007/jhep12%282014%29156

We study the physics of F-theory compactifications on genus-one fibrations without section by using an M-theory dual description. The five-dimensional action obtained by considering M-theory on a Calabi-Yau threefold is compared with a six-dimensiona... Read More about Physics of F-theory compactifications without section.

Coulomb Branch and The Moduli Space of Instantons (2014)
Journal Article
Cremonesi, S., Ferlito, G., Hanany, A., & Mekareeya, N. (2014). Coulomb Branch and The Moduli Space of Instantons. Journal of High Energy Physics, 2014(12), Article 103. https://doi.org/10.1007/jhep12%282014%29103

The moduli space of instantons on ℂ2 for any simple gauge group is studied using the Coulomb branch of N=4N=4 gauge theories in three dimensions. For a given simple group G, the Hilbert series of such an instanton moduli space is computed from the Co... Read More about Coulomb Branch and The Moduli Space of Instantons.

Hyperbolic monopoles, JNR data and spectral curves (2014)
Journal Article
Bolognesi, S., Cockburn, A., & Sutcliffe, P. (2015). Hyperbolic monopoles, JNR data and spectral curves. Nonlinearity, 28(1), 211-235. https://doi.org/10.1088/0951-7715/28/1/211

A large class of explicit hyperbolic monopole solutions can be obtained from JNR instanton data, if the curvature of hyperbolic space is suitably tuned. Here we provide explicit formulae for both the monopole spectral curve and its rational map in te... Read More about Hyperbolic monopoles, JNR data and spectral curves.

Partonic transverse momenta in soft collisions (2014)
Journal Article
Khoze, V., Martin, A., & Ryskin, M. (2014). Partonic transverse momenta in soft collisions. The European Physical Journal C, 74(12), Article 3199. https://doi.org/10.1140/epjc/s10052-014-3199-2

The partonic transverse momentum, kt , distribution plays a crucial role in driving high-energy hadron interactions. If kt is limited we have old fashioned Regge theory. If kt increases with energy the interaction may be described by perturbative QCD... Read More about Partonic transverse momenta in soft collisions.

Thue-Morse constant is not badly approximable (2014)
Journal Article
Badziahin, D., & Zorin, E. (2015). Thue-Morse constant is not badly approximable. International Mathematics Research Notices, 2015(19), 9618-9637. https://doi.org/10.1093/imrn/rnu238

We prove that Thue–Morse constant τTM=0.01101001…2 is not a badly approximable number. Moreover, we prove that τTM(a)=0.01101001…a is not badly approximable for every integer base a≥2 such that a is not divisible by 15. At the same time, we provide a...

Yukawas and discrete symmetries in F-theory compactifications without section (2014)
Journal Article
García-Etxebarria, I., Grimm, T. W., & Keitel, J. (2014). Yukawas and discrete symmetries in F-theory compactifications without section. Journal of High Energy Physics, 2014(11), Article 125. https://doi.org/10.1007/jhep11%282014%29125

In the case of F-theory compactifications on genus-one fibrations without section there are naturally appearing discrete symmetries, which we argue to be associated to geometrically massive U(1) gauge symmetries. These discrete symmetries are shown t... Read More about Yukawas and discrete symmetries in F-theory compactifications without section.

Donor-acceptor electron transport mediated by solitons (2014)
Journal Article
Brizhik, L., Piette, B., & Zakrzewski, W. (2014). Donor-acceptor electron transport mediated by solitons. Physical review E: Statistical, nonlinear, and soft matter physics, 90(5), Article 052915. https://doi.org/10.1103/physreve.90.052915

We study the long-range electron and energy transfer mediated by solitons in a quasi-one-dimensional molecular chain (conjugated polymer, alpha-helical macromolecule, etc.) weakly bound to a donor and an acceptor. We show that for certain sets of par... Read More about Donor-acceptor electron transport mediated by solitons.

Thermoelectric DC conductivities from black hole horizons (2014)
Journal Article

An analytic expression for the DC electrical conductivity in terms of black hole horizon data was recently obtained for a class of holographic black holes exhibiting momentum dissipation. We generalise this result to obtain analogous expressions for... Read More about Thermoelectric DC conductivities from black hole horizons.
