Complex Langevin simulation of a random matrix model at nonzero chemical potential

open access: yesJournal of High Energy Physics, 2018
In this paper we test the complex Langevin algorithm for numerical simulations of a random matrix model of QCD with a first order phase transition to a phase of finite baryon density. We observe that a naive implementation of the algorithm leads to phase

Polymer quantization of the free scalar field and its classical limit

open access: yes, 2010
Building on prior work, a generally covariant reformulation of free scalar field theory on the flat Lorentzian cylinder is quantized using Loop Quantum Gravity (LQG) type `polymer' representations.

Tailoring Redox Active Sites with Dual‐Interfacial Electric Fields for Concurrent Photocatalytic Biomass Valorization and H2 Production

open access: yesAdvanced Functional Materials, EarlyView.
A rationally engineered bifunctional photocatalyst is reported, which achieves simultaneous selective oxidation of biomass‐derived 5‐hydroxymethylfurfural (HMF) to 2,5‐diformylfuran (DFF) and efficient H2 evolution. By precisely positioning Au and Co3O4 on Zn3In2S6 nanosheet, dual interfacial electric fields are well constructed to spatially separate ...

CDT---an Entropic Theory of Quantum Gravity [PDF]

open access: yes, 2010
In these lectures we describe how a theory of quantum gravity may be constructed in terms of a lattice formulation based on so-called causal dynamical triangulations (CDT).

Instanton density operator in lattice QCD from higher category theory

open access: yesSciPost Physics
A natural definition for instanton density operator in lattice QCD has long been desired. We show this problem is, and has to be, solved by higher category theory.

Implementing the three-particle quantization condition including higher partial waves

open access: yesJournal of High Energy Physics, 2019
We present an implementation of the relativistic three-particle quantization condition including both s- and d-wave two-particle channels. For this, we develop a systematic expansion of the three-particle K matrix, K $$ \mathcal{K} $$ df,3, about ...

Quantum Gravity via Causal Dynamical Triangulations

open access: yes, 2013
"Causal Dynamical Triangulations" (CDT) represent a lattice regularization of the sum over spacetime histories, providing us with a non-perturbative formulation of quantum gravity.
