Quark zero modes in intersecting center vortex gauge fields [PDF]

open access: yes, 2002
The zero modes of the Dirac operator in the background of center vortex gauge field configurations in $\R^2$ and $\R^4$ are examined. If the net flux in D=2 is larger than 1 we obtain normalizable zero modes which are mainly localized at the vortices. In

3D-MHD simulations of an accretion disk with star-disk boundary layer [PDF]

open access: yes, 2002
We present global 3D MHD simulations of geometrically thin but unstratified accretion disks in which a near Keplerian disk rotates between two bounding regions with initial rotation profiles that are stable to the MRI.

Zeroing in on Net-Zero

open access: yesUniversity of Colorado Law Review, 2023
One hundred and ninety-seven nations endorsed a target of net-zero greenhouse gas (GHG) emissions by midcentury in the 2021 Glasgow Climate Pact. As countries around the world have begun to develop their plans for deep decarbonization, it has become evident that the private sector will need to deliver much of what is required for the transition to an ...

A Review of Deep Learning Techniques for Forecasting Energy Use in Buildings

open access: yesEnergies, 2021
Buildings account for a significant portion of our overall energy usage and associated greenhouse gas emissions. With the increasing concerns regarding climate change, there are growing needs for energy reduction and increasing our energy efficiency ...

Fermion zero modes in N=2 supervortices [PDF]

open access: yes, 2002
We study the fermionic zero modes of BPS semilocal magnetic vortices in N=2 supersymmetric QED with a Fayet-Iliopoulos term and two matter hypermultiplets of opposite charge.

The Impact of Dispersion on Amplitude and Frequency Noise in a Yb-fiber Laser Comb [PDF]

open access: yes, 2011
We describe a Yb-fiber based laser comb, with a focus on the relationship between net-cavity dispersion and the frequency noise on the comb. While tuning the net cavity dispersion from anomalous to normal, we measure the amplitude noise (RIN), offset ...

The political logic of Net Zero

open access: yes, 2023
Technologies for Carbon Capture, Usage and Storage (CCUS) and Carbon Dioxide Removal (CDR) only represent climate solutions in as much as they go hand in hand with deep emissions reductions. The (future) availability of CCUS and CDR technologies does not mean we can delay or avoid phasing out fossil fuels if we are to have a chance of limiting global ...

Intrinsic Anomalous Hall Effect in Magneto-Chiral States [PDF]

open access: yes, 2014
We show that a finite Hall effect in zero applied magnetic field occurs for partially filled bands in certain time-reversal violating states with zero net flux per unit-cell. These states are the Magneto-chiral states with parameters in the effective one-

Forecasting Energy Use in Buildings Using Artificial Neural Networks: A Review

open access: yesEnergies, 2019
During the past century, energy consumption and associated greenhouse gas emissions have increased drastically due to a wide variety of factors including both technological and population-based.

Neutron Fermi Liquids under the presence of a strong magnetic field with effective nuclear forces [PDF]

open access: yes, 2009
Landau's Fermi Liquid parameters are calculated for non-superfluid pure neutron matter in the presence of a strong magnetic field at zero temperature.
