On the BPS Sector in AdS3/CFT2 Holography
Fortschritte der Physik, Volume 71, Issue 4-5, May 2023., 2023 Abstract The BPS sector in AdS3/CFT2$AdS_3/CFT_2$ duality has been fertile ground for the exploration of gauge/gravity duality, from the match between black hole entropy and the CFT elliptic genus to the construction of large families of geometrical microstates and the identification of the corresponding states in the CFT.

Comments on BRST quantization of strings [PDF]
Journal of High Energy Physics, 2005 The BRST quantization of strings is revisited and the derivation of the path integral measure for scattering amplitudes is streamlined. Gauge invariances due to zero modes in the ghost sector are taken into account by using the Batalin-Vilkovisky formalism.

Homotopy Transfer and Effective Field Theory II: Strings and Double Field Theory
Fortschritte der Physik, Volume 70, Issue 2-3, March 2022., 2022 Abstract We continue our study of effective field theory via homotopy transfer of L∞$L_\infty$‐algebras, and apply it to tree‐level non‐Wilsonian effective actions of the kind discussed by Sen in which the modes integrated out are comparable in mass to the modes that are kept. We focus on the construction of effective actions for string states at fixed

Geometric quantization of the BRST charge [PDF]
Communications in Mathematical Physics, 1992 In the first half of this paper (Sects. 1–4) we generalise the standard geometric quantization procedure to symplectic supermanifolds. In the second half (Sects. 5, 6) we apply this to two examples that exhibit classical BRST symmetry, i.e., we quantize the BRST charge and the ghost number.

Nilpotent Symmetries of a Model of 2D Diffeomorphism Invariant Theory: BRST Approach
Advances in High Energy Physics, Volume 2022, Issue 1, 2022., 2022 Within the framework of the Becchi‐Rouet‐Stora‐Tyutin (BRST) formalism, we discuss the full set of proper BRST and anti‐BRST transformations for a 2D diffeomorphism invariant theory which is described by the Lagrangian density of a standard bosonic string. The above (anti‐)BRST transformations are off‐shell nilpotent and absolutely anticommuting.

Superfield Approaches to a Model of Bosonic String: Curci‐Ferrari‐Type Restrictions
Advances in High Energy Physics, Volume 2022, Issue 1, 2022., 2022 Exploiting the theoretical potential of the modified Bonora‐Tonin superfield approach (MBTSA) as well as the (anti‐)chiral superfield approach (ACSA) to Becchi‐Rouet‐Stora‐Tyutin (BRST) formalism, we derive the complete set of off‐shell nilpotent (anti‐)BRST symmetry transformations corresponding to the classical two‐ (1 + 1) dimensional (2D ...

Double Copy from Homotopy Algebras
Fortschritte der Physik, Volume 69, Issue 8-9, September 2021., 2021 It will be shown that the BRST Lagrangian double copy construction of N = 0 supergravity as the ‘square’ of Yang–Mills theory finds a natural interpretation in terms of homotopy algebras. The authors significantly expand on their previous work arguing the validity of the double copy at the loop level, and they give a detailed derivation of the double ...

Christ–Lee Model: (Anti‐)chiral Supervariable Approach to BRST Formalism
Advances in High Energy Physics, Volume 2021, Issue 1, 2021., 2021 We derive the off‐shell nilpotent of order two and absolutely anticommuting Becchi‐Rouet‐Stora‐Tyutin (BRST), anti‐BRST, and (anti‐)co‐BRST symmetry transformations for the Christ–Lee (CL) model in one (0 + 1)‐dimension (1D) of spacetime by exploiting the (anti‐)chiral supervariable approach (ACSA) to BRST formalism where the quantum symmetry (i.e ...
