In cosmological models where dark energy has a dynamical origin one would expect that a primordial inflationary epoch leaves no imprint on the behavior of dark energy near the present epoch. We...

We study (conformal) field theories with global symmetries in the sector where the value of the global charge Q is large. We find (as expected) that the low energy excitations of this sector are...

In this paper we study a (nearly) scale-invariant helical magnetic field generated during inflation. We show that, if the helicity of such fields is measured, it can be used to determine the...

For G a finitely generated group and g \in G, we say g is detected by a normal subgroup N \lhd G if g \notin N. The depth DG(g) of g is the lowest index of a normal, finite index...

Mathieu Moonshine, the observation that the Fourier coefficients of the elliptic genus on K3 can be interpreted as dimensions of representations of the Mathieu group M24, has been proven...

In 1909, Millikan showed that the charge of electrically isolated systems is quantized in units of the elementary electron charge e. Today, the persistence of charge quantization in small,...

In the second article of this series, we establish the convergence of the loop ensemble of interfaces in the random cluster Ising model to a conformal loop ensemble (CLE) --- thus completely...

This short note presents a comprehensive and pedagogical study of the results in [6] on Lagrangian submanifolds in cotangent bundles T∗X defined by Morse families S:B→R for arbitrary submersions...

We show that when observing the range of a chordal SLEκ curve for κ∈(4,8), it is not possible to recover the order in which the points have been visited. We also derive related results about...

We consider the membrane model, that is the centered Gaussian field on Zd whose covariance matrix is given by the inverse of the discrete Bilaplacian. We impose a δ−pinning condition...

Block spin renormalization group is the main tool used in our program to see symmetry breaking in a weakly interacting many Boson system on a three dimensional lattice at low temperature. It...
