Quantum Criticality via Magnetic Branes

, 2012
Holographic methods are used to investigate the low temperature limit, including quantum critical behavior, of strongly coupled 4-dimensional gauge theories in the presence of an external magnetic field, and finite charge density.

A critical distance parameter for random vibration fatigue life estimation of notched metallic structures in the frequency domain

International Journal of Mechanical System Dynamics
A critical distance parameter is introduced to describe the stress gradient effect of notched metallic structures under random vibration loadings, which is the frequency domain expression of the theory of critical distance (TCD) based line method stress.

Critical scaling of the quantum Wasserstein distance

Physical Review Research
Distinguishing quantum states with minimal sampling overhead is of fundamental importance to teach quantum data to an algorithm. Recently, the quantum Wasserstein distance emerged from the theory of quantum optimal transport as a promising tool in this ...

A Criterion for Brittle Failure of Rocks Using the Theory of Critical Distances [PDF]

Rock Mechanics and Rock Engineering, 2015
This paper presents a new analytical criterion for brittle failure of rocks and heavily overconsolidated soils. Griffith’s model of a randomly oriented defect under a biaxial stress state is used to keep the criterion simple. The Griffith’s criterion is improved because the maximum tensile strength is not evaluated at the boundary of the defect but at ...

Horizon as Critical Phenomenon

, 2016
We show that renormalization group(RG) flow can be viewed as a gradual wave function collapse, where a quantum state associated with the action of field theory evolves toward a final state that describes an IR fixed point.

End of the world brane networks for infinite distance limits in CY moduli space

Journal of High Energy Physics
Dynamical Cobordism provides a powerful method to probe infinite distance limits in moduli/field spaces parameterized by scalars constrained by generic potentials, employing configurations of codimension-1 end of the world (ETW) branes.

Nicolai Hartmanns Critical Ontology and the Critical Realism of the Berlin School of Gestalt Psychology

Gestalt Theory, 2019
The author exemplifies the congruency of essential foundations between the critical realism of the Berlin School of Gestalt Psychology (Gestalt theory) and Nicolai Hartmann’s Critical Ontology.

Adaptive Metrics for Adaptive Samples

Algorithms, 2020
We generalize the local-feature size definition of adaptive sampling used in surface reconstruction to relate it to an alternative metric on Euclidean space.

Dragging a polymer chain into a nanotube and subsequent release

, 2008
We present a scaling theory and Monte Carlo (MC) simulation results for a flexible polymer chain slowly dragged by one end into a nanotube. We also describe the situation when the completely confined chain is released and gradually leaves the tube.
