\section{Motivation} Chromium is considered as the archetypical itinerant antiferromagnet~\cite{1988_Fawcett_RevModPhys, 1994_Fawcett_RevModPhys}. Interestingly, it shares its body-centered cubic crystal structure $Im\overline{3}m$ with the archetypical itinerant ferromagnet $\alpha$-iron and, at melting temperature, ...

\section{INTRODUCTION} The study of the elementary excitations of ultrarelativistic plasmas, such as the quark-gluon plasma, has received much attention in the recent past. (See \cite{BIO96,MLB96} for recent reviews and more references.) The physical picture which emerges is that of a system with two types of ...

A typical example of systems in this form is the cart-pendulum system \cite{mazenc1996adding}, but this structure exhibits also when adding a...

\section{Introduction} We consider the interplay between three paradigmatic quantum states of bosons in rotating lattices: Mott insulators, superfluids, and fractional quantum Hall states. The Mott insulator is found when there is an integer number of particles per lattice site, and the tunneling is sufficiently suppre...

\section{Introduction} \label{sec:intro} It is well known that string theory provides an ultraviolet completion of supergravity -- there are no ultraviolet divergences in perturbative string theory. Since perturbative quantum supergravity arises as the low energy limit of superstring theory it is of interest to see ...

\section{Introduction} Quantum field theories (QFTs) on noncommutative (NC) spacetimes are of recent interest, not only in mathematical physics, but also in particle phenomenology and cosmology. Historically, one of the main reasons for the introduction of NC spacetimes was the hope for a regularization of the diverg...

\section{Introduction} In this paper we examine how the extremal length and the hyperbolic length of a measured lamination change along a Teichm\"uller } \newcommand{\hyp}{{\mathbb H} geodesic. We prove that these lengths are quasi-convex functions of time. The convexity issues in Teichm\"uller } \newcommand{\hyp}{{\...
