Memory, Penrose limits and the geometry of gravitational shockwaves and gyratons
Journal of High Energy Physics, 2018 The geometric description of gravitational memory for strong gravitational waves is developed, with particular focus on shockwaves and their spinning analogues, gyratons.

Quantum Group Gauge Theories and Covariant Quantum Algebras
, 1993 The algebraic formulation of the quantum group gauge models in the framework of the $R$-matrix approach to the theory of quantum groups is given. We consider gauge groups taking values in the quantum groups and noncommutative gauge fields transformed as ...

Shaping Magnetic Liquid Metals Into 3D Leakage‐Free, Shape‐Programmable Structures and Electronics
Advanced Electronic Materials, EarlyView.This research addresses the fluidity‐induced leakage challenge in the 3D patterning of liquid metals (LMs) by utilizing magnetic liquid metals (MLMs). These 3D MLM structures prevent LM leakage, enable shape programmability and reconfigurability, and exhibit self‐healing and enhanced compression resistance.

Wormholes, branes and finite matrices in sine dilaton gravity
Journal of High Energy PhysicsWe compute the double trumpet in sine dilaton gravity via WdW quantization. The wormhole size is discretized. The wormhole amplitude matches the spectral correlation of a finite-cut matrix integral, where matrices have large but finite dimensions.

On the ‘simple’ form of the gravitational action and the self-interacting graviton
Journal of High Energy Physics, 2017 The so-called ΓΓ-form of the gravitational Lagrangian, long known to provide its most compact expression as well as the most efficient generation of the graviton vertices, is taken as the starting point for discussing General Relativity as a theory of ...

Quantum Gravity with the Standard Model
, 2002 A unified theory of four-dimensional gravity together with the standard model is presented, with supersymmetry breaking of M-theory at a TeV. Masses of the the known particles are derived. The cosmological constant is quantum generated to the observed value. Quantum corrections to the classical compactification are analyzed, and the scenario is stable.

Relational Particle Models as Toy Models for Quantum Gravity and Quantum Cosmology [PDF]
AIP Conference Proceedings, 2006 It is argued that substantial portions of both Newtonian particle mechanics and general relativity can be viewed as relational (rather than absolute) theories. I furthermore use the relational particle models as toy models to investigate the problem of time in closed-universe canonical quantum general relativity.

Local phase space and edge modes for diffeomorphism-invariant theories
Journal of High Energy Physics, 2018 We discuss an approach to characterizing local degrees of freedom of a subregion in diffeomorphism-invariant theories using the extended phase space of Donnelly and Freidel [36].
