T T ¯ $$ T\overline{T} $$ deformations of non-relativistic models
Journal of High Energy Physics, 2021 The light-cone gauge approach to T T ¯ $$ T\overline{T} $$ deformed models is used to derive the T T ¯ $$ T\overline{T} $$ deformed matrix nonlinear Schrödinger equation, the Landau-Lifshitz equation, and the Gardner equation.

Why scalar products in the algebraic Bethe ansatz have determinant representation
Journal of High Energy Physics, 2019 We show that the scalar products of on-shell and off-shell Bethe vectors in the algebralic Bethe ansatz solvable models satisfy a system of linear equations. We find solutions to this system for a wide class of integrable models. We also apply our method

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.

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

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 ...

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 ...

Population Ecology, EarlyView.Population size and dynamics fundamentally shape speciation by influencing genetic drift, founder events, and adaptive potential. Small populations may speciate rapidly due to stronger drift, whereas large populations harbor more genetic diversity, which can alter divergence trajectories. We highlight theoretical models that incorporate population size

Integrable open spin chains from flavored ABJM theory
Journal of High Energy Physics, 2017 We compute the two-loop anomalous dimension matrix in the scalar sector of planar N = 3 $$ \mathcal{N}=3 $$ flavored ABJM theory. Using coordinate Bethe ansatz, we obtain the reflection matrices and confirm that the boundary Yang-Baxter equations are ...
