The transport properties of water at extreme pT-conditions govern the evolution of water-rich planets and moons, such as the ice giants (Uranus and Neptune), or satellites possessing rigid icy shells and interior water oceans, like Europa and Enceladus. New theoretical and data-analysis methods have been recently developed to estimate accurate transport coefficients of electronically-gapped materials from ab initio equilibrium molecular dynamics and the Green-Kubo theory of linear response [1-3].  In this talk, we report on recent results on the application of these methods to heat and charge transport in water at the extreme pT-conditions occurring in the interior of water-rich planets and moons, in all the different relevant phases (partially dissociated liquid, solid, and super-ionic) [4]. These results are finally employed to build a model of the thermal evolution of Uranus, which accounts for its hitherto poorly understood very low luminosity [5]. References: [1] A.

But in out-of-equilibrium scenarios, and for high energy eigenstates of generic systems, the scaling of entanglement with time and system size makes a direct application often impossible. However, MPS and more general TNS techniques can still be used to explore some of the most interesting dynamical properties. We have recently introduced a method in which MPO techniques are combined with Chebyshev polynomial expansions to explore spectral properties of quantum many-body Hamiltonians. In particular, we show how this method can be used to probe thermalization of large spin chains without explicitly simulating their time evolution, as well as to compute full and local densities of states.

The physics of nanoscale mechanical dissipation is relevant to sliding nanofriction, to technological themes such as lubrication or finger-touchscreen friction, to soft and granular matter, to nanofrictional emulation in optical lattices, to active matter, to quantum and classical processes in noncontact AFM, and beyond. Between condensed matter physics, nanomechanics, materials science and engineering, this interdisciplinary area is of considerable conceptual value as a modern subject in non-equilibrium physics, and of the potential relevance of neighbouring fields such as fatigue, wear, lubrication, rheology, and biomechanics. As is well established in ICTP Trieste since 1995, we will collect the world community active in these fields, including groups in emerging countries, mixing theoretical, simulation and experimental highlights, and identifying future directions of motion of
research in this lively arena. Topics:     From dissipation to superlubricity     Atomistic friction of 2D layered materials     Nanomanipulation and dynamics of nano-objects at surfaces     Tribology of confined systems and lubricants under shear     Frictional dynamics in soft and active matter     Friction in powders and granular systems     Fundamentals of friction theory     Electronic, magnetic and quantum friction     Surface and bulk  processes and transitions detected by noncontact AFM dissipation     Tribochemistry, triboelectricity, biotribological effects     Trends in experimental and computational techniques Participants are encouraged to submit abstracts of proposed poster contributions.

This requires an understanding of the ensuing multicomponent field theories, their microscopic origins and macroscopic responses. This program will bring together experimentalists, experts working on macroscopic properties and experts working on the underlying microscopic physics that leads to these complex states. The goal will be to achieve an in depth understanding of important physical properties including magnetic response, transport and thermoelectric properties, nature of topological excitations, and fluctuation-induced phases. This will be achieved through an emphasis on the following material systems: twisted bilayer graphene; iron-based superconductors; unconventional superconductivity in Sr2RuO4; UTe2 and related ferromagnetic superconductors; Bi2Se3 based nematic superconductors; j=3/2 superconductors; and novel 2D superconductors Topics: Topological superconducting phases Broken time-reversal superconductors Superconductivity with competing orders Topological Majorana edge states Novel superconducting gap structures Superconductivity from correlated electrons Speakers: A.
