Coexistence of periodic-2 and periodic-3 caustics for nearly circular analytic billiard maps
Vadim Kaloshin, Jianlu Zhang
For symmetrically analytic deformation of the circle (with certain Fourier decaying rate), the necessary condition for the corresponding billiard map to keep the coexistence of per…
A general theory of linear cosmological perturbations: stability conditions, the quasistatic limit and dynamics
Macarena Lagos, Emilio Bellini, Johannes Noller +2
We analyse cosmological perturbations around a homogeneous and isotropic background for scalar-tensor, vector-tensor and bimetric theories of gravity. Building on previous results,…
Dark energy survivals in massive gravity after GW170817: SO(3) invariant
Lavinia Heisenberg, Shinji Tsujikawa
The recent detection of the gravitational wave signal GW170817 together with an electromagnetic counterpart GRB 170817A from the merger of two neutron stars puts a stringent bound…
Coincident General Relativity
Jose Beltran Jimenez, Lavinia Heisenberg, Tomi Koivisto
The metric-affine variational principle is applied to generate teleparallel and symmetric teleparallel theories of gravity. From the latter is discovered an exceptional class which…
Ill-posedness of Leray solutions for the ipodissipative Navier-Stokes equations
Maria Colombo, Camillo De Lellis, Luigi De Rosa
We prove the ill-posedness of Leray solutions to the Cauchy problem for the ipodissipative Navier--Stokes equations, when the dissipative term is a fractional Laplacian wi…
Directed Ramsey number for trees
Matija Bucic, Shoham Letzter, Benny Sudakov
In this paper, we study Ramsey-type problems for directed graphs. We first consider the -colour oriented Ramsey number of , denoted by , which is the…
On gravitational waves in Born-Infeld inspired non-singular cosmologies
Jose Beltran Jimenez, Lavinia Heisenberg, Gonzalo J. Olmo +1
We study the evolution of gravitational waves for non-singular cosmological solutions within the framework of Born-Infeld inspired gravity theories, with special emphasis on the Ed…
Born-Infeld inspired modifications of gravity
Jose Beltran Jimenez, Lavinia Heisenberg, Gonzalo J. Olmo +1
General Relativity has shown an outstanding observational success in the scales where it has been directly tested. However, modifications have been intensively explored in the regi…
Hairy black-hole solutions in generalized Proca theories
Lavinia Heisenberg, Ryotaro Kase, Masato Minamitsuji +1
We present a family of exact black-hole solutions on a static spherically symmetric background in second-order generalized Proca theories with derivative vector-field interactions…
Pair symmetry conversion in driven multiband superconductors
Christopher Triola, Alexander V. Balatsky
It was recently shown that odd-frequency superconducting pair amplitudes can be induced in conventional superconductors subjected to a spatially-nonuniform time-dependent drive. It…
Monochromatic paths in random tournaments
Matija Bucić, Shoham Letzter, Benny Sudakov
We prove that, with high probability, any -edge-colouring of a random tournament on vertices contains a monochromatic path of length . This resolves a…
Observational constraints on generalized Proca theories
Antonio De Felice, Lavinia Heisenberg, Shinji Tsujikawa
In a model of the late-time cosmic acceleration within the framework of generalized Proca theories, there exists a de Sitter attractor preceded by the dark energy equation of state…
Excitonic Gap Formation in Pumped Dirac Materials
Christopher Triola, Anna Pertsova, Robert S. Markiewicz +1
Recent pump-probe experiments demonstrate the possibility that Dirac materials may be driven into transient excited states describable by two chemical potentials, one for the elect…
Refined open intersection numbers and the Kontsevich-Penner matrix model
Alexander Alexandrov, Alexandr Buryak, Ran J. Tessler
A study of the intersection theory on the moduli space of Riemann surfaces with boundary was recently initiated in a work of R. Pandharipande, J. P. Solomon and the third author, w…
Local exponential stabilization for a class of Korteweg-de Vries equations by means of time-varying feedback laws
Jean-Michel Coron, Ivonne Rivas, Shengquan Xiang
We study the exponential stabilization problem for a nonlinear Korteweg-de Vries equa- tion on bounded interval in cases where the linearized control system is not controllable. Th…
Instabilities in Horndeski Yang-Mills inflation
Jose Beltran Jimenez, Lavinia Heisenberg, Ryotaro Kase +2
A non-abelian gauge field with a non-minimal Horndeski coupling to gravity gives rise to a de Sitter solution followed by a graceful exit to a radiation-dominated epoch. In…
Dipolar Dark Matter as an Effective Field Theory
Luc Blanchet, Lavinia Heisenberg
Dipolar Dark Matter (DDM) is an alternative model motivated by the challenges faced by the standard cold dark matter model to describe the right phenomenology at galactic scales. A…
Improved stability for analytic quasi-convex nearly integrable systems and optimal speed of Arnold diffusion
Jianlu Zhang, Ke Zhang
We improve the global Nekhoroshev stability for analytic quasi-convex nearly integrable Hamiltonian systems. The new stability result is optimal, as it matches the fastest speed of…
