Web19 de oct. de 2015 · The AFM order is suppressed gradually under pressure and vanishes at pc = 2.7 GPa, above which an FL-like T2 resistivity develops. We discuss the possibility of a pressure-driven QCP in this low carrier density Kondo lattice and its relation to a field-induced T = 0 boundary at Bc = 2.8 T under atmospheric pressure. Web20 de ago. de 2024 · The ground-state criticality of many-body systems is a resource for quantum-enhanced sensing, namely, the Heisenberg precision limit, provided that one has access to the whole system. We show that, for partial accessibility, the sensing capabilities of a block of spins in the ground state reduces to the sub-Heisenberg limit.

Here we propose a method to enlarge a minute mechanical frequency shift, which is smaller than the linewidth of the mechanical oscillator, into a huge frequency shift of the normal mode. Explicitly, a …
