Integrable field theories from Poisson algebras [PDF]

, 1991
New integrable 1 + 1 dimensional classical field theories are found that include infinite dimensional analogues of N-particle Toda-and Calogero-Moser systems, as well as non-relativistic theories with an interaction that is polynomial in the first ...

Supersymmetry and T T ¯ $$ T\overline{T} $$ deformations

Journal of High Energy Physics, 2019
We propose a manifestly supersymmetric generalization of the solvable T T ¯ $$ T\overline{T} $$ deformation of two-dimensional field theories. For theories with (1, 1) and (0, 1) supersymmetry, the deformation is defined by adding a term to the ...

Metric approach to a T T ¯ $$ \mathrm{T}\overline{\mathrm{T}} $$ -like deformation in arbitrary dimensions

Journal of High Energy Physics, 2022
We consider a one-parameter family of composite fields — bi-linear in the components of the stress-energy tensor — which generalise the T T ¯ $$ \mathrm{T}\overline{\mathrm{T}} $$ operator to arbitrary space-time dimension d ≥ 2. We show that they induce

Entanglement and confinement in coupled quantum systems

Journal of High Energy Physics, 2021
We study some general properties of coupled quantum systems. We consider simple interactions between two copies of identical Hamiltonians such as the SYK model, Pauli spin chains with random magnetic field and harmonic oscillators.

Supersymmetric integrable scattering theories with unstable particles [PDF]

, 2004
We propose scattering matrices for N=1 supersymmetric integrable quantum field theories in 1+1 dimensions which involve unstable particles in their spectra.

Symplectic deformations of integrable field theories and AdS/CFT

Physics Letters B, 2014
Relativistic integrable field theories like the sine-Gordon equation have an infinite set of conserved charges. In a light-front formalism these conserved charges are closely related to the integrable modified KdV hierarchy at the classical level.

Irrelevant deformations of chiral bosons

Journal of High Energy Physics, 2021
We study T T ¯ $$ \mathrm{T}\overline{\mathrm{T}} $$ deformations of chiral bosons using the formalism due to Sen. For arbitrary numbers of left- and right-chiral bosons, we find that the T T ¯ $$ \mathrm{T}\overline{\mathrm{T}} $$ -deformed Lagrangian ...

Network topology drives population temporal variability in experimental habitat networks

Population Ecology, EarlyView.
Habitat patches connected by dispersal pathways form habitat networks. We explored how network topology affects population outcomes in laboratory experiments using a model species (Daphnia carinata). Central habitat nodes in complex lattice networks exhibited lower temporal variability in population sizes, suggesting they support more stable ...
