Color Superconductivity in N = 2 Supersymmetric Gauge Theories

We study vacuum structure of N = 2 supersymmetric (SUSY) QCD, based on the gauge group SU(2) with Nf = 2 flavors of massive hypermultiplet quarks, in the presence of non-zero baryon chemical potential (μ). The theory has a classical vacuum preserving baryon number symmetry, when a mass term, which breaks N = 2 SUSY but preserves N = 1 SUSY, for the adjoint gauge chiral multiplet (mad) is introd...

Cognitive Neuroscience: Trickle-Down Theories of Vision

The visual cortex is not a passive recipient of information: predictions about incoming stimuli are made based on experience, partial information and the consequences of inferences. A combination of imaging studies in the human brain has now led to the proposal that the orbitofrontal cortex is a key source of top-down predictions leading to object recognition.

Thermal and quantum depletion of superconductivity in narrow junctions created by controlled electromigration

Superconducting nanowires currently attract great interest due to their application in single-photon detectors and quantum-computing circuits. In this context, it is of fundamental importance to understand the detrimental fluctuations of the superconducting order parameter as the wire width shrinks. In this paper, we use controlled electromigration to narrow down aluminium nanoconstrictions. We...

Down the rabbit hole with theories of class S

We review some of the properties of 3d N = 4 theories obtained by dimensionally reducing theories of class S. We study 3d partition functions, and certain limits thereof, for such theories, and the properties implied for these by 3d mirror symmetry.

Implicit theories concerning the intelligence of individuals with Down syndrome

Studies over the past three decades have shown that learning difficulties are not only determined by neurological disorders, but also by motivational and/or socio-cognitive factors Among these factors, implicit theories of intelligence (also referred to as conceptions, mindsets or beliefs about intelligence) are key elements. The belief that intelligence is fixed (entity theory), as opposed to ...
