The two classes of low energy spectra in finite carbon nanotubes

Magdalena Marganska, Piotr Chudzinski, Milena Grifoni

Electrons in carbon nanotubes (CNTs) possess spin and orbital degrees of freedom. The latter is inherited from the bipartite graphene lattice with two inequivalent Dirac points. Th…

Direct control of the small-scale energy balance in 2D fluid dynamics

Jason Frank, Benedict Leimkuhler, Keith Myerscough

We explore the direct modification of the pseudo-spectral truncation of 2D, incompressible fluid dynamics to maintain a prescribed kinetic energy spectrum. The method provides a me…

Cholesterics of colloidal helices: Predicting the macroscopic pitch from the particle shape and thermodynamic state

Simone Dussi, Simone Belli, René van Roij +1

Building a general theoretical framework to describe the microscopic origin of macroscopic chirality in (colloidal) liquid crystals is a long-standing challenge. Here, we combine c…

IIB Supergravity and the E6(6) covariant vector-tensor hierarchy

Franz Ciceri, Bernard de Wit, Oscar Varela

IIB supergravity is reformulated with a manifest local USp(8) invariance that makes the embedding of five-dimensional maximal supergravities transparent. In this formulation the te…

Propositional Logics of Dependence

Fan Yang, Jouko Väänänen

In this paper, we study logics of dependence on the propositional level. We prove that several interesting propositional logics of dependence, including propositional dependence lo…

The Holographic Goldstino

Riccardo Argurio, Matteo Bertolini, Daniele Musso +2

We find the fingerprints of the Goldstino associated to spontaneous supersymmetry breaking in a prototype holographic model for a strongly coupled field theory. The Goldstino massl…

Giant negative magnetoresistance driven by spin-orbit coupling at the LAO/STO interface

M. Diez, A. M. R. V. L. Monteiro, G. Mattoni +6

The LAO/STO interface hosts a two-dimensional electron system that is unusually sensitive to the application of an in-plane magnetic field. Low-temperature experiments have reveale…

Time Evolution of Entanglement Entropy in Quenched Holographic Superconductors

Xiaojian Bai, Bum-Hoon Lee, Li Li +2

We investigate the dynamical evolution of entanglement entropy in a holographic superconductor model by quenching the source term of the dual charged scalar operator. By access to…

Supermassive Black Hole Formation at High Redshifts via Direct Collapse in a Cosmological Context

Jun-Hwan Choi, Isaac Shlosman, Mitchell C. Begelman

We study the early stage of the formation of seed supermassive black holes via direct collapse in dark matter (DM) halos, in the cosmological context. We perform high-resolution zo…

On functional equations leading to exact solutions for standing internal waves

Felix Beckebanze, Grant Keady

The Dirichlet problem for the wave equation is a classical example of a problem which is not well-posed. Nevertheless, it has been used to model internal waves oscillating sinusoid…
