The critical transition of Coulomb impurities in gapped graphene

Journal of High Energy Physics, 2020
The effect of supercritical charge impurities in graphene is very similar to the supercritical atomic collapses in QED for Z > 137, but with a much lower critical charge.

Topology of Born-Infeld AdS black holes in 4D novel Einstein-Gauss-Bonnet gravity

Physics Letters B, 2022
The topological classification of critical points of black holes in 4D Einstein-Gauss-Bonnet gravity coupled to Born-Infeld theory is investigated. Considered independently, Born-infeld corrections to the Einstein action alter the topological charge of ...

N=8 non-BPS Attractors, Fixed Scalars and Magic Supergravities [PDF]

, 2007
We analyze the Hessian matrix of the black hole potential of N=8, d=4 supergravity, and determine its rank at non-BPS critical points, relating the resulting spectrum to non-BPS solutions (with non-vanishing central charge) of N=2, d=4 magic ...

Critical behaviour in charging of electric vehicles

New Journal of Physics, 2015
The increasing penetration of electric vehicles over the coming decades, taken together with the high cost to upgrade local distribution networks and consumer demand for home charging, suggest that managing congestion on low voltage networks will be a crucial component of the electric vehicle revolution and the move away from fossil fuels in ...

Quantum criticality in a double quantum-dot system [PDF]

, 2006
We discuss the realization of the quantum-critical non-Fermi liquid state, originally discovered within the two-impurity Kondo model, in double quantum-dot systems.

Critical nucleus charge in a superstrong magnetic field

EPJ Web of Conferences, 2018
Due to strong enhancement of loop effects in a superstrong magnetic field (B ≫ m2=e3) the Coulomb potential becomes screened. This phenomenon dramatically changes the dependence of the electron energy levels on magnetic field. In particular, the freezing

Stripe formation: A quantum critical point for cuprate superconductors

, 1998
We discuss the effects of a quantum critical point located nearby optimum doping and related to local charge segregation (stripe phase). The fluctuations in the critical region produce at the same time a strong pairing mechanism and a non-Fermi liquid ...

Quantum Hall Charge Kondo Criticality

, 2017
The long-thought charge Kondo effects have recently been experimentally realized in the quantum Hall regime. This experiment, supported by numerics, exemplifies the realization of two-channel Kondo state, a non-Fermi Liquid, and its crossover to the one-channel counterpart, a Fermi liquid.

WRTU-16T: Write-Enhanced Low-Power Radiation-Tolerant SRAM for Space Applications

Applied Sciences
In space, high-energy particle radiation poses a serious threat to the data stability and reliability of SRAM. Existing radiation-tolerant techniques, such as Triple Modular Redundancy (TMR) and Error Correction Code (ECC), have disadvantages such as ...
