We introduce the concept of a local metric Gaussian free field (GFF) $h$, which is random coupled with $h$ in such way that it depends locally on certain sense. This definition analog set for $h$. establish general criteria two metrics same GFF to be bi-Lipschitz equivalent each other and a.s. determined by Our results are used subsequent works prove existence, uniqueness, basic properties $\ga...

We propose a semi-suspended device structure and construct nanogapped, hysteresis-free field-effect transistors (FETs), based on the van der Waals stacking technique. The structure, which features channel above submicrometer-long wedge-like nanogap, is fulfilled by transferring ultraclean boron nitride-supported MoS 2 channels directly onto dielectric-spaced vertical source/drain stacks. Electr...

We employ the free field realisation of $\mathfrak{psu}(1,1|2)_1$ world-sheet theory to constrain correlators string on ${\rm AdS}_3\times {\rm S}^3\times \mathbb{T}^4$ with unit NS-NS flux. In particular, we directly obtain unusual delta function localisation these onto branched covers boundary S}^2$ by (genus zero) -- this is key property which makes equivalence dual symmetric orbifold manife...

Pseudo entropy is an interesting quantity with a simple gravity dual, which generalizes entanglement such that it depends on both initial and final state. Here we reveal the basic properties of pseudo in quantum field theories by numerically calculating this for set two-dimensional free scalar Ising spin chain. We extend Gaussian method two parameters: mass $m$ dynamical exponent $z$. This comp...
