Maximally symmetric three-Higgs-doublet model (2021)
Journal Article

We consider the general three-Higgs-doublet model (3HDM) and identify all limits that lead to exact Standard Model (SM) alignment. After discussing the underlying symmetries that can naturally enforce such an alignment, we focus on the most economic... Read More about Maximally symmetric three-Higgs-doublet model.

Journal Article

Capillary liquid bridges are ubiquitous in nature and are present in many industrial processes.

A Marvellous Sign and A Fiery Globe: A Medieval English Report of Ball Lightning (2022)
Journal Article

We describe an entry in a twelfth century monastic chronicle, compiled and composed by Gervase of Canterbury (c. 1145–c. 1210), which gives a credible description of ball lightning. It predates the earliest known report of the phenomenon from England... Read More about A Marvellous Sign and A Fiery Globe: A Medieval English Report of Ball Lightning.

Probing the magnetic polaron state in the ferromagnetic semiconductor HgCr2Se4 with muon-spin spectroscopy and resistance-fluctuation measurements (2022)
Journal Article

Combined resistance noise and muon-spin relaxation (μSR) measurements of the ferromagnetic semiconductor HgCr2Se4 suggest a degree of magnetoelectric coupling and provide evidence for the existence of isolated magnetic polarons. These form at elevate... Read More about Probing the magnetic polaron state in the ferromagnetic semiconductor HgCr2Se4 with muon-spin spectroscopy and resistance-fluctuation measurements.

Enhanced electron-phonon coupling near an electronic quantum phase transition (2022)
Journal Article

I construct a simple model to demonstrate that when the manyelectron quantum state of a material is near a quantum phase transition and the vibrational motion of a phonon explores the potential energy surface near the transition point, then an impene...

Critical assessment of pressure estimates in volcanic plumbing systems: The case study of Popocatépetl volcano, Mexico (2021)
Journal Article

Most geobarometers use chemical compositions of minerals and their host melt to estimate crystallization pressures. Crystal structural parameters such as cell and site volumes are not usually considered despite their known sensitivity to pressure. He...

Muon sites in PbF2 and YF3: Decohering environments and the role of anion Frenkel defects (2021)
Journal Article

Muons implanted into ionic fluorides often lead to a so-called F– μ –F state, in which the time evolution of the muon spin contains information about the geometry and nature of the muon site. Nuclei more distant from the muon than the two nearest-nei... Read More about Muon sites in PbF2 and YF3: Decohering environments and the role of anion Frenkel defects.

Spiro donor–acceptor TADF emitters: naked TADF free from inhomogeneity caused by donor acceptor bridge bond disorder. Fast rISC and invariant photophysics in solid state hosts (2022)
Journal Article

We have studied the thermally activated delayed fluorescence (TADF) properties of the spiro-bridged donor–acceptor molecule, 10-phenyl-10H,10′H-spiro[acridine-9,9-anthracen]-10′-one, (ACRSA) in guest–host films and used it as a probe to explore the d...

Experimental evidence of a change of exchange anisotropy sign with temperature in Zn-substituted Cu2OSeO3 (2021)
Journal Article

We report small-angle neutron scattering from the conical state in a single crystal of Zn-substituted Cu 2 OSeO 3 . Using a 3D vector-field magnet to reorient the conical wave vector, our measurements show that the magnitude of the conical wave vecto...

Engineering spin wave spectra in thick Ni80Fe20 rings by using competition between exchange and dipolar fields (2021)
Journal Article

Control of the spin wave dynamics in nanomagnetic elements is very important for the realization of a broad range of novel magnonic devices.

Magma recharge patterns control eruption styles and magnitudes at Popocatépetl volcano (Mexico) (2022)
Journal Article

Diffusion chronometry has produced petrological evidence that magma recharge in mafic to intermediate systems can trigger volcanic eruptions within weeks to months. However, less is known about longer-term recharge frequencies and durations priming m...
