On-the-fly ab initio semiclassical evaluation of vibronic spectra at finite temperature

Jiri Vanicek, Tomislav Begusic

To compute and analyze vibrationally resolved electronic spectra at zero temperature, we have recently implemented the on-the-fly ab initio extended thawed Gaussian approximation [A. Patoz et al., J. Phys. Chem. Lett. 9, 2367 (2018)], which accounts for an ...

Maximum-energy records in glassy energy landscapes

Riccardo Ravasio

We study the evolution of the maximum energy E-max(t) reached between time 0 and time t in the dynamics of simple models with glassy energy landscapes, after an instant quench from infinite temperature to a target temperature T. Through a detailed descript ...

Decisive role of nuclear quantum effects on surface mediated water dissociation at finite temperature

Michele Ceriotti, Mariana Rossi Carvalho

Water molecules adsorbed on inorganic substrates play an important role in several technological applications. In the presence of light atoms in adsorbates, nuclear quantum effects (NQEs) influence the structural stability and the dynamical properties of t ...

Complex heavy-quark potential and Debye mass in a gluonic medium from lattice QCD

Yannis Burnier

We improve and extend our study of the complex in-medium heavy-quark potential and its Debye mass m(D) in a gluonic medium with a finer scan around the deconfinement transition and newly generated ensembles closer to the thermodynamic limit. On the lattice ...

The Bayesian reconstruction of the in-medium heavy quark potential from lattice QCD and its stability

Yannis Burnier

We report recent results of a non-perturbative determination of the static heavy-quark potential in quenched and dynamical lattice QCD at finite temperature. The real and imaginary part of this complex quantity are extracted from the spectral function of W ...

Frédéric Mila, Jérôme Dufour

Low-dimensional quantum magnets at finite temperatures present a complex interplay of quantum and thermal fluctuation effects in a restricted phase space. While some information about dynamical response functions is available from theoretical studies of th ...

Thermodynamic properties of average-atom interatomic potentials for alloys

William Curtin, Wolfram Georg Nöhring

The atomistic mechanisms of deformation in multicomponent random alloys are challenging to model because of their extensive structural and compositional disorder. For embedded-atom-method interatomic potentials, a formal averaging procedure can generate an ...

Thermodynamic properties of highly frustrated quantum spin ladders: Influence of many-particle bound states

Frédéric Mila, Bruce Normand

Quantum antiferromagnets have proven to be some of the cleanest realizations available for theoretical, numerical, and experimental studies of quantum fluctuation effects. At finite temperatures, however, the additional effects of thermal fluctuations in t ...

Static Quark-Antiquark Potential in the Quark-Gluon Plasma from Lattice QCD

Yannis Burnier

We present a state-of-the-art determination of the complex valued static quark-antiquark potential at phenomenologically relevant temperatures around the deconfinement phase transition. Its values are obtained from nonperturbative lattice QCD simulations u ...

Friedel vs. Labusch: the strong/weak pinning transition in solute strengthened metals

William Curtin

Solute strengthening in substitutional alloys can be classified into two categories, strong-pinning (Friedel) and weak-pinning (Labusch), each with its own characteristic scaling with concentration and temperature. The transition between the two strengthen ...

Heat wave propagation in a nonlinear chain

Francesco Piazza

We investigate the propagation of temperature perturbations in an array of coupled nonlinear oscillators at finite temperature. We evaluate the response function at equilibrium and show how the memory effects affect the diffusion properties. A comparison w ...
