On the spin content of the classical massless Rarita-Schwinger system
SciPost Physics Proceedings, 2023 We analyze the Rarita-Schwinger massless theory in the Lagrangian and Hamiltonian approaches. At the Lagrangian level, the standard gamma-trace gauge fixing constraint leaves a 1/2 and a 3/2 propagating Poincaré group helicities. At the Hamiltonian level,

About the geographic grid of the three-dimensional hypersphere [PDF]
E3S Web of Conferences, 2020 According to the Poincaré conjecture (1904) proved by Grigory Perelman (2002-2003) that any simply connected compact three- dimensional manifold without edges is homeomorphic to a three- dimensional hypersphere [1], to solve the problems of visualizing ...

Is the horizon of an eternal black hole really smooth?
Journal of High Energy Physics, 2023 We point out that in many eternal black holes, including a Schwarzschild eternal black hole and an eternal black hole in AdS 5, instant folded strings are created in the past wedge and render the region just outside the horizon singular.

Spectral gap for some invariant log-concave probability measures [PDF]
, 2010 We show that the conjecture of Kannan, Lov\'{a}sz, and Simonovits on isoperimetric properties of convex bodies and log-concave measures, is true for log-concave measures of the form $\rho(|x|_B)dx$ on $\mathbb{R}^n$ and $\rho(t,|x|_B) dx$ on $\mathbb{R}^{

The Global Attractor of the Allen-Cahn Equation on the Sphere
Frontiers in Applied Mathematics and Statistics, 2020 In this paper we study the attractor of a parabolic semiflow generated by a singularly perturbed PDE with a non-linear term given by a bistable potential, in an oval surface; the Allen-Cahn equation being a prototypical example.

Neuromodulation: Technology at the Neural Interface, EarlyView., 2021 Abstract Background Posttraumatic stress disorder (PTSD) is associated with autonomic dysfunction as indicated by deficits in the sympathetic and parasympathetic nervous systems. These abnormalities are expressed as elevated heart rate and reduced heart rate variability (HRV), respectively.

Journal of High Energy Physics, 2020 With one exception, all known non-supersymmetric AdS4 and AdS5 vacua of gauged maximal supergravities that descend from string and M theory have been shown to have modes with mass below the BF bound.

Moduli space holography and the finiteness of flux vacua
Journal of High Energy Physics, 2021 A holographic perspective to study and characterize field spaces that arise in string compactifications is suggested. A concrete correspondence is developed by studying two-dimensional moduli spaces in supersymmetric string compactifications.

Entanglement of Purification and Multiboundary Wormhole Geometries [PDF]
, 2019 We posit a geometrical description of the entanglement of purification for subregions in a holographic CFT. The bulk description naturally generalizes the two-party case and leads to interesting inequalities among multi-party entanglements of ...

Local BPS invariants : enumerative aspects and wall-crossing [PDF]
, 2020 We study the BPS invariants for local del Pezzo surfaces, which can be obtained as the signed Euler characteristic of the moduli spaces of stable one-dimensional sheaves on the surface S. We calculate the Poincaré polynomials of the moduli spaces for the
