Sub-GeV dark matter detection with electron recoils in carbon nanotubes
Abstract Directional detection of Dark Matter particles (DM) in the MeV mass range could be accomplished by studying electron recoils in large arrays of parallel carbon nanotubes. In a scattering process with a lattice electron, a DM particle might...

Generalized pure Lovelock gravity
Abstract We present a generalization of the n-dimensional (pure) Lovelock Gravity theory based on an enlarged Lorentz symmetry. In particular, we propose an alternative way to introduce a cosmological term. Interestingly, we show that the usual pure ...

Live event reconstruction in an optically read out GEM-based TPC
Abstract Combining strong signal amplification made possible by Gaseous Electron Multipliers (GEMs) with the high spatial resolution provided by optical readout, highly performing radiation detectors can be realized. An optically read out GEM-based...

Nonexistence of degenerate horizons in static vacua and black hole uniqueness
Abstract We show that in any spacetime dimension D ≥ 4 , degenerate components of the event horizon do not exist in static vacuum configurations with...

Effect of the chameleon scalar field on brane cosmological evolution
Abstract We have investigated a brane world model in which the gravitational field in the bulk is described both by a metric tensor and a minimally coupled scalar field. This scalar field is taken to be a chameleon with an appropriate potential...

ElecSus: Extension to arbitrary geometry magneto-optics
Abstract We present a major update to ElecSus, a computer program and underlying model to calculate the electric susceptibility of an alkali-metal atomic vapour. Knowledge of the electric susceptibility of a medium is essential to predict its...

Exotic quantum states for charmed baryons at finite temperature
Abstract The significantly screened heavy-quark potential in hot medium provides the possibility to study exotic quantum states of three-heavy-quark systems. By solving the Schrödinger equation for a three-charm-quark system at finite temperature,...

Analogue simulation with the use of artificial quantum coherent structures
Abstract An explosive development of quantum technologies since 1999 allowed the creation of arrays of natural and artificial quantum unit elements (viz. trapped ions and superconducting qubits), which maintain certain degree of quantum coherence...

Coherent gamma photon generation in a Bose–Einstein condensate of 135mCs
Abstract We have identified a mechanism of collective nuclear de-excitation in a Bose–Einstein condensate of 135Cs atoms in their isomeric state, ...

Low temperature electroweak phase transition in the Standard Model with hidden scale invariance
Abstract We discuss a cosmological phase transition within the Standard Model which incorporates spontaneously broken scale invariance as a low-energy theory. In addition to the Standard Model fields, the minimal model involves a light dilaton,...

Diboson interference resurrection
Abstract High-energy diboson processes at the LHC are potentially powerful indirect probes of heavy new physics, whose effects can be encapsulated in higher-dimensional operators or in modified Standard Model couplings. An obstruction however comes...

Delta-ray Production in MCNP 6.2.0
Abstract Secondary electrons in the form of delta-rays, also referred to as knock-on electrons, have been a feature of MCNP for electron and positron transport for over 20 years. While MCNP6 now includes transport for a suite of heavy-ions and...

Minima of multi-Higgs potentials with triplets of Δ(3 n 2 ) and Δ(6 n 2 )
Abstract We analyse the minima of scalar potentials for multi-Higgs models where the scalars are arranged as either one triplet or two triplets of the discrete symmetries ...
