The two-dimensional material ${\mathrm{Cr}}_{2}{\mathrm{Ge}}_{2}{\mathrm{Te}}_{6}$ is a member of the class insulating van der Waals (vdW) magnets. Here, using high resolution angle-resolved photoemission spectroscopy in detailed temperature dependence study, we identify clear response electronic structure to dimensional crossover form two distinct scales marking onsets modifications structure. Specifically, observe Te $p$-orbital-dominated bands undergo changes at Curie transition ${T}_{C}$...
Magnetic frustrations and dimensionality play an important role in determining the nature of magnetic long-range order how it melts at temperatures above ordering transition T_{N}. In this Letter, we use large-scale Monte Carlo simulations to study these phenomena a class frustrated Ising spin models two spatial dimensions. We find that melting into isotropic gaslike paramagnet proceeds via intermediate stage where classical spins remain anisotropically correlated. This correlated exists...
We report on the quantum confinement in SrTiO3 (STO) wells (QWs) grown by molecular beam epitaxy. The QW structure consists of LaAlO3 (LAO) and STO layers LAO substrate. Structures with different thicknesses ranging from two to ten unit cells were characterized. Optical properties (complex dielectric function) measured spectroscopic ellipsometry range 1.0 eV–6.0 eV at room temperature. observed that absorption edge was blue-shifted approximately 0.39 as well thickness reduced cells. This...
The environmental interaction is a fundamental consideration in any controlled quantum system. While an with dissipative bath can lead to decoherence, it also provide desirable emergent effects including induced spin-spin correlations. In this Letter, we show that under quite general conditions, bosonic induce long-range ordered phase, without the inclusion of additional direct couplings. Through quantum-to-classical mapping and classical Monte Carlo simulation, investigate $T=0$ phase...
We numerically study the dissipative transverse field Ising model in a bosonic bath with Ohmic spectral density. present Monte Carlo techniques for studying this previously inaccessible regimes of strong frustration. then consider well-studied limit model, infinite-separation, and further show that even finite separations there is no magnetic ordering associated case an infinite cutoff frequency. discuss future applications method.
