Spontaneous symmetry breaking in tensor theories

Journal of High Energy Physics, 2019
In this work we study spontaneous symmetry breaking patterns in tensor models. We focus on the patterns which lead to effective matrix theories transforming in the adjoint of U(N).

Target space entanglement in quantum mechanics of fermions at finite temperature

Journal of High Energy Physics, 2022
We consider the target space entanglement in quantum mechanics of non-interacting fermions at finite temperature. Unlike pure states investigated in [1], the (Rényi) entanglement entropy for thermal states does not follow a simple bound because all ...

Gauge Theory and Supergravity Duality in the PP-Wave Background [PDF]

, 2005
We test the matrix theory conjecture in the pp-wave by studying two-body interactions between gravitons and membranes. We compute the one-loop effective potential of matrix theory and compare it to the light cone Lagrangian of linearized supergravity. We

M -strings and AdS3 solutions to M-theory with small $$ \mathcal{N} $$ = (0, 4) supersymmetry [PDF]

, 2020
We construct a general class of (small) N = (0, 4) superconformal solutions in M-theory of the form AdS3 × S3/ℤk × CY2, foliated over an interval. These solutions describe M-strings in M5-brane intersections.

Target space entanglement entropy

Journal of High Energy Physics, 2023
We define a notion of target space entanglement entropy. Rather than partitioning the base space on which the theory is defined, we consider partitions of the target space.

Fixing an ambiguity in two dimensional string theory using string field theory

Journal of High Energy Physics, 2020
In a recent paper, Balthazar, Rodriguez and Yin found some remarkable agreement between the results of c = 1 matrix model and D-instanton corrections in two dimensional string theory.

Target space entanglement in quantum mechanics of fermions and matrices

Journal of High Energy Physics, 2021
We consider entanglement of first-quantized identical particles by adopting an algebraic approach. In particular, we investigate fermions whose wave functions are given by the Slater determinants, as for singlet sectors of one-matrix models. We show that

Aspects of supersymmetry in multiple membrane theories [PDF]

, 2011
PhDThis thesis consists of two parts. In the rst part we investigate the worldvolume supersymmetry algebra of multiple membrane theories. We begin with a description of M-theory branes and their intersections from the perspective of spacetime and ...

Supersymmetric M2-brane matrix model with restricted volume-preserving deformations: Lorentz covariance and BPS spectrum

Journal of High Energy Physics
We present a novel supersymmetric Lorentz-covariant matrix model for M2-branes in M-theory, constructed via the framework of Restricted Volume-Preserving Deformations (RVPD) which is a residual symmetry from gauge-fixed volume-preserving diffeomorphisms.
