Spacetime colour reconnection in Herwig 7

open access: yesEuropean Physical Journal C: Particles and Fields, 2019
We present a model for generating spacetime coordinates in the Monte Carlo event generator Herwig 7, and perform colour reconnection by minimizing a boost-invariant distance measure of the system.

Seeking for a Fundamental Quantum Arrow of Time: Time Reversal and the Symmetry-To-Reality Inference in Standard Quantum Mechanics

open access: yesFrontiers in Physics, 2018
In this paper I shall shed some doubts on a widely-held claim: standard quantum mechanics is time-reversal invariant, and thereby, blind to the direction of time.

CPT invariance and neutrino physics

open access: yes, 2010
CPT invariance in neutrino physics has attracted attention after the revival of the hypothetical idea that neutrino and antineutrino might have nonequal masses ($m_{\bar } \neq m_ $) when realizing neutrino oscillations as a new sensitive phenomenon to search for the violation of this fundamental symmetry.

Physical invariants for nonlinear orthotropic solids

open access: yesInternational Journal of Solids and Structures, 2011
Seven invariants, with immediate physical interpretation, are proposed for the strain energy function of nonlinear orthotropic elastic solids. Three of the seven invariants are the principal stretch ratios and the other four are squares of the dot product between the two preferred directions and two principal directions of the right stretch tensor.

L lines, C points and Chern numbers: understanding band structure topology using polarization fields

open access: yesNew Journal of Physics, 2017
Topology has appeared in different physical contexts. The most prominent application is topologically protected edge transport in condensed matter physics. The Chern number, the topological invariant of gapped Bloch Hamiltonians, is an important quantity

De Sitter quantum gravity and the emergence of local algebras

open access: yesJournal of High Energy Physics
Quantum theories of gravity are generally expected to have some degree of non-locality, with familiar local physics emerging only in a particular limit. Perturbative quantum gravity around backgrounds with isometries and compact Cauchy slices provides an
