SUMMARY:SPS Journal Club: 'Tensionless String Limits in AdS5/CFT4 and the Sharpened Distance Conjecture'
DESCRIPTION:Strings\, Pheno and the Swampland (SPS) Journal Club. Every Thursday at 12:00 in the Red Room. \n\n\nTitle: Tensionless String Limits in AdS5/CFT4 and the Sharpened Distance Conjecture\n\nSpeaker: Gabriel Fenati (IFT)\n\nVenue&Time: Red Room / 12:00\n\nAbstract: Based on work in progress with M. Montero and I. Valenzuela. We extend the results of [2410.07309] by showing that all 4d Lagrangian SCFTs satisfy the bound of the Sharpened Distance Conjecture in the large N limit.  We also provide an example of a quiver SCFT\, dual to a stringy AdS background\, where the bound is violated by taking a different kind of semi-classical limit\, in which the number of gauge factors is taken to be large at fixed N.

SUMMARY:Pheno Journal Club: 'Infinite Heat Order in 3+1 Dimensions'
DESCRIPTION:Samuel Rosende (IFT) will present “Infinite Heat Order in 3+1 Dimensions”\n\nVenue&Time: Gray Room 2 / 12:00\n\nAbstract:\n\nWe investigate whether spontaneous symmetry breaking can persist up to arbitrarily high temperature in ultraviolet-complete quantum field theories in four spacetime dimensions. We focus on completely asymptotically free models with gauge group SU(Nc1)×SU(Nc2) and two complex scalar fields\, each transforming in the fundamental representation of one gauge factor and singlet under the other. The scalar potential contains quartic self-interactions together with a negative portal coupling between the two sectors. In the Veneziano limit\, this class of theories was previously shown to admit fixed-flow trajectories for which one scalar acquires a negative thermal mass at asymptotically large temperature\, leading to symmetry non-restoration. Here we extend that analysis to finite numbers of colours and flavours. We derive the finite-N fixed-flow equations\, compute the leading 1/N corrections to the large-N solutions\, and solve the full finite-N system numerically. We find explicit finite-N benchmark theories for which the scalar potential remains bounded from below\, the gauge sector is asymptotically free\, and one scalar thermal mass stays negative at arbitrarily high temperature. This provides an explicit perturbative example of infinite heat order in a four-dimensional ultraviolet-complete quantum field theory with a finite field content.
