Hausdorff dimensions for shared endpoints of disjoint geodesics in the directed landscape [PDF]
Electronic Journal of Probability, 2019 Within the Kardar-Parisi-Zhang universality class, the space-time Airy sheet is conjectured to be the canonical scaling limit for last passage percolation models.

Effective counting of simple closed geodesics on hyperbolic surfaces [PDF]
Journal of the European Mathematical Society (Print), 2019 We prove a quantitative estimate, with a power saving error term, for the number of simple closed geodesics of length at most $L$ on a closed hyperbolic surface of genus $g$.

Information Geometry in Roegenian Economics
Entropy, 2022 We characterise the geometry of the statistical Roegenian manifold that arises from the equilibrium distribution of an income of noninteracting identical economic actors.

Geometry of geodesics through Busemann measures in directed last-passage percolation [PDF]
Journal of the European Mathematical Society (Print), 2019 We consider planar directed last-passage percolation on the square lattice with general i.i.d. weights and study the geometry of the full set of semi-infinite geodesics in a typical realization of the random environment. The structure of the geodesics is

Equivalence of Gibbons-Werner method to geodesics method in the study of gravitational lensing [PDF]
Physical Review D, 2019 The Gibbons-Werner method where the Gauss-Bonnet theorem is applied to study the gravitational deflection angle has received much attention recently. In this paper, we study the equivalence of the Gibbons-Werner method to the standard geodesics method ...

Quasinormal modes of black holes with multiple photon spheres
Journal of High Energy Physics, 2022 For a static and spherically symmetric black hole, a photon sphere is composed of circular null geodesics of fixed radius, and plays an important role in observing the black hole.

Frontiers in Human Neuroscience, 2016 In pain management as well as other clinical applications of neuromodulation, it is important to consider the timing parameters influencing activity-dependent plasticity, including pulsed versus sustained currents, as well as the spatial action of ...

European Physical Journal C: Particles and Fields, 2023 The existence of null circular geodesics in the background of non-extremal spherically symmetric asymptotically flat black holes has been proved in previous works.

The forces and Penrose process in Friedman spacetime
Physics of Complex Systems, 2021 In this paper, we compare the force expressions in both comoving synchronous and Ellis coordinate systems in Friedman-Robertson-Walker spacetime in order to understand how the coordinate transformation affects the inertial forces.

, 2021 We describe, in an intrinsic way and using the global chart provided by Ito's parallel transport, a generalisation of the notion of geodesic (as critical path of an energy functional) to diffusion processes on Riemannian manifolds. These stochastic processes are no longer smooth paths but they are still critical points of a regularised stochastic ...
