Joint Constraints on the Hubble Constant and Cosmic Baryon Density from Localized Fast Radio Bursts and DESI DR2 Baryon Acoustic Oscillations
Ji-Guo Zhang, Tian-Nuo Li, Guo-Hong Du +3
Fast radio bursts (FRBs) probe free-electron columns along cosmological sightlines through their dispersion measures (DMs), whereas baryon acoustic oscillations (BAO) constrain cos…
A unified picture of phonon anomalies in crystals and glasses
Alessio Zaccone
Phonon spectra in solids often display anomalies that defy the simple Debye law, most prominently the van Hove singularity in crystals and the boson peak in glasses. Although tradi…
Open quantum systems with particle and bath driven by time-dependent fields
Daniele Gamba, Bingyu Cui, Alessio Zaccone
We derive a generalized quantum Langevin equation and its fluctuation-dissipation relation describing the quantum dynamics of a tagged particle interacting with a medium (environme…
Global population crisis scenarios predicted by a general nonlinear dynamical model
Alessio Zaccone, Kostya Trachenko
We show that a simple nonlinear differential equation (originally studied in the physics of disordered systems) is able to mathematically describe the global population growth over…
Hyperballistic transport in dense systems of charged particles under ac electric fields
Daniele Gamba, Bingyu Cui, Alessio Zaccone
The Langevin equation is ubiquitously employed to numerically simulate plasmas, colloids and electrolytes. However, the usual assumption of white noise becomes untenable when the s…
Theory of superconductivity in thin films under an external electric field
Alessio Zaccone, Vladimir M. Fomin
The supercurrent field effect is experimentally realized in various nano-scale devices, based on the superconductivity suppression by external electric fields being effective for c…
Molecular-level relation between intra-particle glass transition temperature and stability of colloidal suspensions
C. Anzivino, A. Zaccone
In many colloidal suspensions, the dispersed colloidal particles are amorphous solids resulting from vitrification. A crucial open problem is understanding how colloidal stability…
Theory of heavy-quarks contribution to the quark-gluon plasma viscosity
Alessio Zaccone
The shear viscosity of quark gluon plasma is customarily estimated in the literature using kinetic theory, which, however, is well known to break down for dense interacting systems…

We provide a mathematical description, based on d-wave Eliashberg theory, of the strong correlation between the experimentally observed softening of Raman modes associated with in-…
Glassy heat capacity from overdamped phasons and a hypothetical phason-induced superconductivity in incommensurate structures
Cunyuan Jiang, Alessio Zaccone, Chandan Setty +1
Phasons are collective low-energy modes that appear in disparate condensed matter systems such as quasicrystals, incommensurate structures, fluctuating charge density waves, and Mo…

Giovanni Alberto Ummarino
The phenomenology of overdoped high Tc superconductors can be described by a one band d wave Eliashberg theory where the mechanism of superconducting coupling is mediated by antife…
Anharmonic theory of superconductivity and its applications to emerging quantum materials
Chandan Setty, Matteo Baggioli, Alessio Zaccone
The role of anharmonicity on superconductivity has often been disregarded in the past. Recently, it has been recognized that anharmonic decoherence could play a fundamental role in…

Thermal expansion and the glass transition
P. Lunkenheimer, A. Loidl, B. Riechers +2
Melting is well understood in terms of the Lindemann criterion, essentially stating that crystalline materials melt when the thermal vibrations of their atoms become such vigorous…
