On the Morse index of nonorientable minimal surfaces in

Carlos Andrés Toro Cardona, Carlos Granada-Palacio, Ivan Miranda

We compute the Morse index of several complete nonorientable minimal surfaces immersed in Euclidean three-space. In particular, we prove that the Meeks minimal Möbius band has Mors…

Singly periodic minimal Wente torus with ends

Carlos Andrés Toro Cardona

We construct singly periodic minimal surfaces in parametrized by rhombic lattices and foliated by spherical curvature lines. As an application we find new examples o…

Minimal surfaces with closed curvature lines

Carlos Andrés Toro Cardona

We investigate complete non-orientable minimal surfaces of finite total curvature in such that their ends are foliated by closed lines of curvature. This condition o…

Non-existence of free boundary minimal Möbius bands in the unit three-ball

Carlos Andrés Toro Cardona

We prove the impossibility of constructing free boundary minimal Möbius bands in the Euclidean ball . This answers in the negative a question proposed by I. Fernández…

Four-point correlation modular bootstrap for OPE densities

Carlos Cardona, Cynthia Keeler, William Munizzi

In this work we apply the lightcone bootstrap to a four-point function of scalars in two-dimensional conformal field theory. We include the entire Virasoro symmetry and consider no…

Instability of a uniform electric field in pure non-Abelian Yang-Mills theory

Carlos Cardona, Tanmay Vachaspati

We study the Schwinger process in a uniform non-Abelian electric field using a dynamical approach in which we evolve an initial quantum state for gluonic excitations. We evaluate t…

The neutrino gravitational memory from a core collapse supernova: phenomenology and physics potential

Mainak Mukhopadhyay, Carlos Cardona, Cecilia Lunardini

General Relativity predicts that the passage of matter or radiation from an asymmetrically-emitting source should cause a permanent change in the local space-time metric. This phen…

Virasoro blocks at large exchange dimension

Carlos Cardona

In this paper, we analyze Virasoro conformal blocks in the limit when the operator exchange dimension is taking to be large in comparison with the other parameters dependence of th…

Correlation functions at the bulk point singularity from the gravitational eikonal S-matrix

Carlos Cardona

The bulk point singularity limit of conformal correlation functions in Lorentzian signature acts as a microscope to look into local bulk physics in AdS. From it we can extract flat…

Resummation at finite conformal spin

Carlos Cardona, Sunny Guha, Surya Kiran Kanumilli +1

We generalize the computation of anomalous dimension and correction to OPE coefficients at finite conformal spin considered recently in \cite{arXiv:1806.10919, arXiv:1808.00612} to…

Anomalous dimensions at finite conformal spin from OPE inversion

Carlos Cardona, Kallol Sen

We compute anomalous dimensions of higher spin operators in Conformal Field Theory at arbitrary space-time dimension by using the OPE inversion formula of \cite{Caron-Huot:2017vep}…

OPE inversion in Mellin space

Carlos Cardona

The fundamental ingredients that build the observables in conformal field theory are the spectrum of operators and the OPE coefficients, or equivalently, the two- and three-point f…

Mellin-(Schwinger) representation of One-loop Witten diagrams in AdS

Carlos Cardona

In this paper we consider Witten diagrams at one loop in AdS space for scalar theory. After using Schwinger parametrization to trivialize the space-time loop integration,…

S-matrix singularities and CFT correlation functions

Carlos Cardona, Yu-tin Huang

In this note, we explore the correspondence between four-dimensional flat space S-matrix and two-dimensional CFT proposed by Pasterski et al. We demonstrate that the factorization…

On the linearity of Regge trajectory at large transfer energy

Carlos Cardona, Yu-tin Huang, Tsung-Hsuan Tsai

In this note we consider the four-point function of identical scalar operators in its Mellin representation. For CFTs, taking the large scaling dimension limit of the Mellin amplit…

Cross-ratio Identities and Higher-order Poles of CHY-integrand

Carlos Cardona, Bo Feng, Humberto Gomez +1

The evaluation of generic Cachazo-He-Yuan(CHY)-integrands is a big challenge and efficient computational methods are in demand for practical evaluation. In this paper, we propose a…

Elimination and recursions in the scattering equations

Carlos Cardona, Chrysostomos Kalousios

We use the elimination theory to explicitly construct the (n-3)! order polynomial in one of the variables of the scattering equations. The answer can be given either in terms of a…
