Universal twinkling exponents for spectral fluctuations associated with mixed chaology [PDF]

, 2000
For systems that are neither fully integrable nor fully chaotic, bifurcations of periodic orbits give rise to semiclassically emergent singularities in the fluctuating part Nfl of the energy-level counting function. The bifurcations dominate the spectral

SCALING RELATIONS FOR THE CLG'S CRITICAL EXPONENTS

We consider, in any dimension, the constrained lattice gas introduced by Rossi et al., which is an exclusion process on a d-dimensional lattice following the additional constraint that only particles with at least one occupied neighbour can jump.

Carving out OPE space and precise O(2) model critical exponents [PDF]

Journal of High Energy Physics, 2019
We develop new tools for isolating CFTs using the numerical bootstrap. A “cutting surface” algorithm for scanning OPE coefficients makes it possible to find islands in high-dimensional spaces.

Unifying the Anderson transitions in Hermitian and non-Hermitian systems

Physical Review Research, 2022
Non-Hermiticity enriches the tenfold Altland-Zirnbauer symmetry class into the 38-fold symmetry class, where critical behavior of the Anderson transitions (ATs) has been extensively studied recently.

Probing phase structure of black holes with Lyapunov exponents

Journal of High Energy Physics, 2022
We conjecture that there exists a relationship between Lyapunov exponents and black hole phase transitions. To support our conjecture, Lyapunov exponents of the motion of particles and ring strings are calculated for Reissner-Nordström-AdS black holes ...

Universal Scaling and Critical Exponents of the Anisotropic Quantum Rabi Model. [PDF]

Physical Review Letters, 2017
We investigate the quantum phase transition of the anisotropic quantum Rabi model, in which the rotating and counterrotating terms are allowed to have different coupling strengths.

On critical exponents for self-similar collapse

Journal of High Energy Physics, 2020
We explore systematically perturbations of self-similar solutions to the Einstein-axion-dilaton system, whose dynamics are invariant under spacetime dilations combined with internal 𝔰𝔩(2, ℝ) transformations.

Minimally subtracted six loop renormalization of $O(n)$-symmetric $\phi^4$ theory and critical exponents [PDF]

, 2017
We present the perturbative renormalization group functions of $O(n)$-symmetric $\phi^4$ theory in $4-2\varepsilon$ dimensions to the sixth loop order in the minimal subtraction scheme.

Long-Range Critical Exponents near the Short-Range Crossover. [PDF]

Physical Review Letters, 2017
The d-dimensional long-range Ising model, defined by spin-spin interactions decaying with the distance as the power 1/r^{d+s}, admits a second-order phase transition with continuously varying critical exponents.
