Convergence of scaled asymptotically-free self-interacting random walks to Brownian motion perturbed at extrema*

We consider a family of one-dimensional self-interacting walks whose dynamics characterized by a monotone weight function w on N ∪ {0}. The weight function takes the form w(n) = (1 + 2p Bn−p + O(n−1−κ))−1, for some B ∈ R, κ > 0 and p ∈ (0, 1]. Our main mod ...

Stable systems with power law conditions for Poisson hail

Thomas Mountford, Zhe Wang

We consider Poisson hail models and characterize up to boundaries the collection of critical moments which guarantee stability. In particular, we treat the case of infinite speed of propagation. ...

Magneto-optical study of metamagnetic transitions in the antiferromagnetic phase of alpha-RuCl3

Zhe Wang

alpha-RuCl3 is a promising candidate material to realize the so far elusive quantum spin liquid ground state. However, at low temperatures, the coexistence of different exchange interactions couple the effective pseudospins into an antiferromagnetically zi ...

Nonequilibrium quasistationary spin disordered state in ?-RuCl3

Zhe Wang

We photoexcite high-energy holon-doublon pairs as a way to alter the magnetic free energy landscape and resulting phase diagram of the frustrated honeycomb magnet ??-RuCl3. The pair recombination through multimagnon emission is tracked through the time evo ...

A driven tagged particle in asymmetric exclusion processes

Zhe Wang

We consider the asymmetric exclusion process with a driven tagged particle on Z which has different jump rates from other particles. When the non-tagged particles have non-nearest-neighbor jump rates , we show that the tagged particle can have a speed whic ...

Muon flux measurement at China Jinping Underground Laboratory

Zhe Wang, Mourad Chouaki, Jian Tang, Qian Liu, Ghulam Hussain, Tong Xu

China Jinping Underground Laboratory (CJPL) is ideal for studying solar, geo-, and supernova neutrinos. A precise measurement of the cosmic-ray background is essential in proceeding with R&D research for these MeV-scale neutrino experiments. Using a 1-ton ...

Low-temperature monoclinic layer stacking in atomically thin CrI3 crystals

Marco Gibertini, Zhe Wang

Chromium triiodide, CrI3, is emerging as a promising magnetic two-dimensional semiconductor where spins are ferromagnetically aligned within a single layer. Potential applications in spintronics arise from an antiferromagnetic ordering between adjacent lay ...

Persistence of Magnetism in Atomically Thin MnPS3 Crystals

Marco Gibertini, Dumitru Dumcenco, Zhe Wang

The magnetic state of atomically thin semiconducting layered antiferromagnets such as CrI3 and CrCI3 can be probed by forming tunnel barriers and measuring their resistance as a function of magnetic field (H) and temperature (T). This is possible because t ...

Determining the phase diagram of atomically thin layered antiferromagnet CrCl3

Marco Gibertini, Dumitru Dumcenco, Zhe Wang

Changes in the spin configuration of atomically thin, magnetic van der Waals multilayers can cause drastic modifications in their opto-electronic properties. Conversely, the opto-electronic response of these systems provides information about the magnetic ...

Origin and Magnitude of 'Designer' Spin-Orbit Interaction in Graphene on Semiconducting Transition Metal Dichalcogenides

Helmuth Berger, Zhe Wang

We use a combination of experimental techniques to demonstrate a general occurrence of spin-orbit interaction (SOI) in graphene on transition metal dichalcogenide (TMD) substrates. Our measurements indicate that SOI is ultrastrong and extremely robust, des ...
