Analytic integrability for holographic duals with J T ¯ $$ J\overline{T} $$ deformations
Journal of High Energy Physics, 2020 We probe warped BTZ ×S 3 geometry with various string solitons and explore the classical integrability criteria of the associated phase space configurations using Kovacic’s algorithm.

Operator growth and Krylov construction in dissipative open quantum systems
Journal of High Energy Physics, 2022 Inspired by the universal operator growth hypothesis, we extend the formalism of Krylov construction in dissipative open quantum systems connected to a Markovian bath.

Branching High‐Order Exceptional Points in Non‐Hermitian Optical Systems
Laser &Photonics Reviews, Volume 16, Issue 9, September 2022., 2022 Exceptional points are complex‐valued spectral singularities that lead to a host of intriguing features such as loss‐induced transparency—a counterintuitive process in which an increase in the system's overall loss can lead to enhanced transmission.

Unveiling atom‐photon quasi‐bound states in hybrid plasmonic‐photonic cavity
Nanophotonics, Volume 11, Issue 14, Page 3307-3317, July 2022., 2022 Abstract Dissipation, often associated with plasmons, leads to decoherence and is generally considered fatal for quantum nonlinearities and entanglement. Counterintuitively, by introducing a dissipative plasmonic nanoantenna into a typical cavity quantum electrodynamics (QED) system, we unveil the wide existence of the atom‐photon quasi‐bound state ...

Halo Properties in Helium Nuclei from the Perspective of Geometrical Thermodynamics
Annalen der Physik, Volume 534, Issue 2, February 2022., 2022 8He nucleus is modelled in quantitative geometrical thermodynamics (QGT) as two summed unitary entities: the alpha particle core and the 4‐neutron halo. The halo is in turn a holomorphic pair of 2‐neutron halos, each of which is also a holomorphic pair. With a scale length given by the proton, QGT gives the 8He matter radius as 2.510 fm.

Real Liouvillian Extensions of Partial Differential Fields [PDF]
Symmetry, Integrability and Geometry: Methods and Applications, 2021 In this paper, we establish Galois theory for partial differential systems defined over formally real differential fields with a real closed field of constants and over formally p-adic differential fields with a p-adically closed field of constants.

A Numerical Procedure to Evaluate Memory Effects in Non‐Equilibrium Coarse‐Grained Models
Advanced Theory and Simulations, Volume 4, Issue 4, April 2021., 2021 A numerical method is presented to analyze reaction coordinates from simulation data in terms of memory effects. The method allows to efficiently construct non‐stationary memory kernels. It is tested with the example of NaCl dissociation in water. Abstract When developing coarse‐grained models of complex processes out of equilibrium, one encounters the

Liouvillian First Integrals for Generalized Liénard Polynomial Differential Systems [PDF]
Advanced Nonlinear Studies, 2013 Abstract We study the Liouvillian first integrals for the generalized Liénard polynomial differential systems of the form xʹ = y, yʹ = -g(x) - f(x)y, where g(x) and f(x) are arbitrary polynomials such that 2 ≤ deg g ≤ deg f.

Liouvillian and Analytic First Integrals for the Brusselator System [PDF]
Journal of Nonlinear Mathematical Physics, 2012 We characterize the Liouvillian and analytic first integrals for the polynomial differential systems of the form x' = a − (b + 1)x + x2y, y' = bx − x2y, with a, b ∈ R, called the Brusselator differential systems.

Journal of High Energy Physics, 2018 We show that the string worldsheet theory of Gaiotto-Maldacena holographic duals to N=2 $$ \mathcal{N}=2 $$ superconformal field theories generically fails to be classically integrable.
