Link power coordination for energy conservation in complex communication networksOct 10 2010Communication networks consume huge, and rapidly growing, amount of energy. However, a lot of the energy consumption is wasted due to the lack of global link power coordination in these complex systems. This paper proposes several link power coordination ... More

Existence of two-step replica symmetry breaking for the spherical mixed p-spin glass at zero temperatureFeb 08 2018We provide the first examples of two-step replica symmetry breaking (2-RSB) models for the spherical mixed p-spin glass at zero temperature. Precisely, we show that for a certain class of mixtures, the Parisi measure at zero temperature is purely atomic ... More

Simulation of beam-beam induced emittance growth in the HL-LHC with crab cavitiesOct 22 2014The emittance growth in the HL-LHC due to beam-beam effects is examined by virtue of strong-strong computer simulations. A model of the transverse damper and the noise level have been tuned to simulate the emittance growth in the present LHC. Simulations ... More

Inhomogeneous spin diffusion of transversely polarized fermions at a high temperature limitJul 10 2016Aug 17 2016We study the transverse spin diffusion of trapped polarized Fermi gases based on the quantum Boltzmann equation. The inhomogeneous dephasing can not completely removed by the echo pulse and might have significant correction to the demagnetization dynamics. ... More
