An article published in the UK Guardian on 11/10/2013 with the headline 'Genetics outweighs teaching, Gove advisor tells his boss' reported a leaked document written by special advisor Dominic Cummings to the then UK Secretary of State for Education, Michael Gove. The article generated 3008 on-line reader comments from the public. These reader comments offer a naturalistic opportunity to unders...

We propose a method of generating multipartite entanglement by considering the interaction of a system of N two-level atoms in a cavity of high quality factor with a strong classical driving field. It is shown that, with a judicious choice of the cavity detuning and the applied coherent field detuning, vacuum Rabi coupling produces a large number of important multipartite entangled states. It i...

The interaction between an atom and a one mode external driving field is an ubiquitous problem in many branches of physics and is often modeled using the Rabi Hamiltonian. In this paper we present a series of analytically solvable Hamiltonians that approximate the Rabi Hamiltonian and compare our results to the Jaynes-Cummings model which neglects the so-called counter-rotating term in the Rabi...

We investigate the entanglement dynamics between two dipole-coupled qubits interacting with vacuum or thermal fields of lossless resonators. Double Jaynes-Cummings model and two-atom Jaynes-Cummings model are considered taking into account detuning and direct dipole-dipole interaction. Using the dressed-states technique we derive the exact solutions for models under consideration. The computer ...

The UK government’s assertion that it placed a protective shield around care homes in the first wave of covid-19 pandemic is “complete nonsense,” prime minister’s former chief adviser has claimed. Speaking to MPs on 26 May front parliamentary health and science select committees’ inquiry into lessons learnt from pandemic, Dominic Cummings said he was shocked April 2020 find home residents who ...

England’s health and social care secretary, Matt Hancock, blamed “scientific consensus” for key government failings during the covid-19 pandemic, as he came out fighting against his critics this week. Giving evidence to MPs on 10 June at science select committees’ joint inquiry into lessons learnt from pandemic,1 Hancock defended both government’s record rebutted claims that prime minister’s f...
