Multi-charged moments and symmetry-resolved Rényi entropy of free compact boson for multiple disjoint intervals
Himanshu Gaur, Urjit A. Yajnik
We study multi-charged moments and symmetry-resolved Rényi entropy of free compact boson for multiple disjoint intervals. The Rényi entropy evaluation involves computing the partit…
Symmetry Resolved Entanglement Entropy in Hyperbolic de Sitter Space
Himanshu Gaur, Urjit A. Yajnik
In this paper, we study the relation between entanglement and global internal symmetries on de Sitter space. We consider two symmetric causally disconnected regions in the hyperbol…
Charge imbalance resolved Rényi negativity for free compact boson: Two disjoint interval case
Himanshu Gaur, Urjit A. Yajnik
In this paper, we study the symmetry decomposition of Rényi negativity into charge imbalance sectors for the 1+1 dimensional free compact boson field with a global U(1) symmetry in…
Ferromagnetic instability in PAAI in the sky
R. B. MacKenzie, M. B. Paranjape, U. A. Yajnik
We study an idealised plasma of fermions, coupled through an abelian gauge force , and which is asymmetric in that the masses of the oppositely charged species are greatly…
Vacuum Decay Induced by False Skyrmions
Éric Dupuis, Mareike Haberichter, Richard MacKenzie +2
We consider the Skyrme model modified by the addition of mass terms which explicitly break chiral symmetry and pick out a specific point on the model's target space as the unique t…
Non-perturbative to perturbative QCD via the FFBRST
Haresh Raval, Bhabani Prasad Mandal, Urjit A. Yajnik
Recently a new type of quadratic gauge was introduced in QCD in which the degrees of freedom are suggestive of a phase of abelian dominance. In its simplest form it is also free of…
