Magnetic properties of a graphene nanoisland structure have been studied by the effective-field theory with correlations. It consists of two triangular interpenetrating sublattices described by Ising model with mixed spin. The results show the exchange coupling and the anisotropy have important influence...
The phase diagram of the first layer of H$_2$ adsorbed on top of a single graphene sheet has been calculated by means of a series of diffusion Monte Carlo (DMC) simulations. We have found that, as in the case of $^4$He, the ground state of molecular hydrogen is a $\\sqrt3 imes...

or thinner samples is only seen with graphene encapsulation20,21,22. Our unprotected 1 u.c. BSCCO-2212 devices are superconducting and we do not find a direct correlation between thickness and mobility leading us to conclude that the degree of disorder is the important parameter. This result...
understanding required to control the behaviour of water. Here we combine a range of computational approaches to enable a first-principles-level investigation of a single layer of water within a graphene-like channel. We find that monolayer water exhibits surprisingly rich and diverse phase behaviour...

The gap equation for Dirac quasiparticles in monolayer graphene in constant magnetic and pseudomagnetic fields, where the latter is due to strain, is studied in a low-energy effective model with contact interactions. Analyzing solutions of the gap equation, the phase diagram of the system in the...
We investigate adiabatic quantum pumping through a normal-metal–"insulator"–superconductor (NIS) junction in a monolayer of graphene. The pumped current ... M Alos-Palop,M Blaauboer - 《Physical Review B Condensed Matter》 被引量: 13发表: 2011年 ...
remains an analytic crossover. In addition, we develop an algorithm to directly simulate the asymptotically strong magnetic field limit of QCD. We find strong evidence for a first-order deconfinement phase transition in this limiting theory, implying the presence of a critical point in the QCD pha...
Such states are typically formed through phase transitions under non-equilibrium conditions and the final state is reached through processes that span a large range of timescales. Conventionally, phase diagrams of materials are thought of as static, without temporal evolution. However, many functional ...
