Scale anomalies, states, and rates in conformal field theory

Marc Gillioz

This paper presents two methods to compute scale anomaly coefficients in conformal field theories (CFTs), such as the c anomaly in four dimensions, in terms of the CFT data. We first use Euclidean position space to show that the anomaly coefficient of a fo ...

Evolution of the Valley Position in Bulk Transition-Metal Chalcogenides and Their Monolayer Limit

Dumitru Dumcenco, Yi Zhang, Bo Zhou, Zahid Hussain, Gang Xu, Kai Yan

Layered transition metal chalcogenides with large spin orbit coupling have recently sparked much interest due to their potential applications for electronic, optoelectronic, spintronics, and valleytronics. However, most current understanding of the electro ...

Numerical characterization of bump formation in the runaway electron tail

Joan Decker

Runaway electrons are generated in a magnetized plasma when the parallel electric field exceeds a critical value. For such electrons with energies typically reaching tens of MeV, the Abrahamâ Lorentzâ Dirac (ALD) radiation force, in reaction to the synch ...

Valley polarization by spin injection in a light-emitting van der Waals heterojunction

Andras Kis, Oriol López Sánchez, Dmitry Ovchinnikov, Adrien Victor Allain, Shikhar Misra

The band structure of transition metal dichalcogenides (TMDCs) with valence band edges at different locations in the momentum space could be harnessed to build devices that operate relying on the valley degree of freedom. To realize such valleytronic devic ...

Free-standing electronic character of monolayer

Andras Kis, Dumitru Dumcenco, Olivier Renault, Yen-Cheng Kung, Ming-Wei Chen, Hokwon Kim

We have evaluated as-grown MoS2 crystals, epitaxially grown on a monocrystalline sapphire by chemical vapor deposition (CVD), with direct electronic band-structure measurements by energy-filtered k-space photoelectron emission microscopy performed with a c ...

From Compact Semi-Toric Systems To Hamiltonian S-1-Spaces

Silvia Sabatini

We show how any labeled convex polygon associated to a compact semi-toric system, as de fined by V (u) over tilde Ngoc, determines Karshon's labeled directed graph which classifies the underlying Hamiltonian S-1-space up to isomorphism. Then we characteriz ...

Nonexistence of smooth solutions for a full viscous isentropic liquid crystal system in three dimensions

Tudor Ratiu

We prove that the smooth solutions to the Cauchy problem for a full isentropic three-dimensional liquid crystal nematodynamic equations with conserved mass, linear momentum, and dissipating total energy, can lose classical smoothness within a finite time. ...

Consequences of Broken Translational Symmetry in FeSexTe1-x

Marco Grioni, Luca Moreschini, Ping-Hui Lin, Davide Innocenti

We investigate the consequences of broken translational symmetry in the superconductor FeSexTe1-x using angle-resolved photoemission spectroscopy. We find that the intensity does not follow the periodicity dictated by the crystal structure, owing to the fo ...
