Quantum tunneling and trace anomaly [PDF]
Physics Letters B, 2009 We compute the corrections, using the tunneling formalisim based on a quantum WKB approach, to the Hawking temperature and Bekenstein-Hawking entropy for the Schwarzschild black hole. The results are related to the trace anomaly and are shown to be equivalent to findings inferred from Hawking's original calculation based on path integrals using zeta ...

An open quantum systems approach to proton tunnelling in DNA
Communications Physics, 2022 The genetic stability of DNA suffers from proton transfer along the hydrogen bonds that can lead to tautomerisation, creating mutations. The authors theoretically examine the tautomerisation of the GuanineCytosine (G-C) nucleotide base-pair using an open

Microwave spectroscopy on a double quantum dot with an on-chip Josephson oscillator
, 2000 We present measurements on microwave spectroscopy on a double quantum dot with an on-chip microwave source. The quantum dots are realized in the two-dimensional electron gas of an AlGaAs/GaAs heterostructure and are weakly coupled in series by a ...

Quantum gravity effect on the Hawking radiation of charged rotating BTZ black hole
, 2018 In this study, the quantum gravity effect on the tunnelling radiation of charged massive spin-0 scalar particle from 2+1 dimensional charged rotating Banados-Teitelboim-Zanelli (BTZ) black hole is looked into by using the Hamilton-Jacobi approach.

Tunnelling amplitudes through localised external potentials from Feynman diagram summation
European Physical Journal C: Particles and FieldsCurrently there is no general theory of quantum tunnelling of a particle through a potential barrier which is compatible with QFT. We present a complete calculation of tunnelling amplitudes for a scalar field for some simple potentials using quantum ...

Advanced Functional Materials, EarlyView.A previously unreported coordination motif stabilising single Fe atoms by indigo chelation and pyridyl coordination on Au(111) has been revealed. By using planar tritopic pyridyl linkers (TPyB), extended 2D porous networks of indigo3(TPyB)2Fe6 form. These networks can be crystalline or vitreous and offer an environment where individual coordination ...
