Signature reversal invariance [PDF]
, 2006 We consider the signature reversing transformation of the metric tensor g_ab goes to -g_ab induced by the chiral transformation of the curved space gamma matrices gamma_a goes to gamma gamma_a in spacetimes with signature (S,T), which also induces a (-1)^

A note on the S-matrix bootstrap for the 2d O(N) bosonic model
Journal of High Energy Physics, 2018 In this work we apply the S-matrix bootstrap maximization program to the 2d bosonic O(N) integrable model which has N species of scalar particles of mass m and no bound states.

Conformal bootstrap deformations
Journal of High Energy Physics, 2022 We explore the space of extremal functionals in the conformal bootstrap. By recasting the bootstrap problem as a set of non-linear equations parameterized by the CFT data, we find an efficient algorithm for converging to the extremal solution ...

Wegner-Houghton equation in low dimensions [PDF]
, 1999 We consider scalar field theories in dimensions lower than four in the context of the Wegner-Houghton renormalization group equations (WHRG). The renormalized trajectory makes a non-perturbative interpolation between the ultraviolet and the infrared ...

Supersymmetric gauged Double Field Theory: Systematic derivation by virtue of \textit{Twist} [PDF]
, 2015 In a completely systematic and geometric way, we derive maximal and half-maximal supersymmetric gauged double field theories in lower than ten dimensions.

Capacity of entanglement in local operators
Journal of High Energy Physics, 2021 We study the time evolution of the excess value of capacity of entanglement between a locally excited state and ground state in free, massless fermionic theory and free Yang-Mills theory in four spacetime dimensions.

Critical theories for the pseudogap Kondo problem [PDF]
, 2004 We discuss quantum phase transitions in the pseudogap Kondo problem, which describes a magnetic moment coupled to conduction electrons with a power-law density of states, rho(omega) ~ |omega|^r.

Anomaly Matching and Symmetry-Protected Critical Phases in SU(N) Spin Systems in 1+1 Dimensions. [PDF]
Physical Review Letters, 2018 We study (1+1)-dimensional SU(N) spin systems in the presence of global SU(N) rotation and lattice translation symmetries. Knowing the mixed anomaly of the two symmetries at low energy, we identify, by the anomaly matching argument, a topological index ...

BPS property and its breaking in 1+1 dimensions [PDF]
Physical Review D, 2018 We show that the BPS property is a generic feature of field theories in (1+1) dimensions, which does not put any restriction on the action. Here, by BPS solutions we understand static solutions which i) obey a lower-order Bogomolny-type equation in ...

Entanglement dynamics after a quench in Ising field theory: a branch point twist field approach
Journal of High Energy Physics, 2019 We extend the branch point twist field approach for the calculation of entanglement entropies to time-dependent problems in 1+1-dimensional massive quantum field theories.
