We have uncovered striking, yet puzzling, evidence of a clear violation of this assumption. We use the prototypical example of an XYZ chain with no external field in a ring geometry with an odd number of sites and both ferromagnetic and antiferromagnetic interactions. In such a setting, even at finite sizes, we are able to calculate directly the spontaneous magnetizations that are traditionally used as order parameters to characterize the system's phases. While when ferromagnetic interactions dominate, we recover the expected behavior, when the system is governed by one antiferromagnetic interaction, the magnetizations decay algebraically to zero with the system size and are not staggered, despite the AFM coupling. We term this behavior ferromagnetic mesoscopic magnetization. With two competing AFM interactions a third, new type of order can emerge, with a magnetization profile that varies in space with an incommensurate pattern. This modulation is the result of a ground state degeneracy which leads to a breaking of translational invariance. The transition between the two latter cases is signaled by an intensive discontinuity in the first derivative of the ground state energy: this is thus not a standard first-order QPT, but rather looks like a boundary QPT, in a system without boundaries (a Boundary-less Wetting Transitions), but with frustrated boundary conditions.

Europe/Rome 2020-04-06 08:00:00 2020-04-09 22:00:00 Dissipation Mechanisms in Nano/Mesoscale Tribological Systems | (smr 3435) Nano/mesoscale mechanical and rheological response with dissipation has become, thanks to the very broad range of experimental/theoretical approaches, a novel local diagnostic and even spectroscopic tool, as well as a playground of sophisticated non-equilibrium statistical physics. 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. A number of short oral presentation slots will be available for some of them upon selection. Speakers: A. BENASSI, Chiesi Farmaceutici, Italy R.
