Long-lived phonons.
We have previously demonstrated that optical phonons and polaritons in simple compound semiconductors, e.g. , GaP, possess dephasing times in the picosecond and femtosecond time scales. ' In high-purity materials the source of the dephasing is dominated by three-particle anharmonic interactions. Others have demonstrated that longitudinal acoustic (LA) and transverse acoustic (TA) phonons decay ...
متن کاملLong-Lived Broadcast Encryption
In a broadcast encryption scheme, digital content is encrypted to ensure that only privileged users can recover the content from the encrypted broadcast. Key material is usually held in a “tamperresistant,” replaceable, smartcard. A coalition of users may attack such a system by breaking their smartcards open, extracting the keys, and building “pirate decoders” based on the decryption keys they...
متن کاملFast, Long-Lived Renaming
We consider wait-free solutions to the renaming problem for shared-memory multiprocessing systems [3, 5]. In the renaming problem, processes are required to choose new names in order to reduce the size of their name space. Previous solutions to the renaming problem have time complexity that is dependent on the size of the original name space, and allow processes to acquire names only once. In t...
متن کاملLong-Lived Planetesimal Discs
We investigate the survival of planetesimal discs over Gyr timescales, using a unified approach that is applicable to all Keplerian discs of solid bodies – dust grains, asteroids, planets, etc. Planetesimal discs can be characterized locally by four parameters: surface density, semimajor axis, planetesimal size and planetesimal radial velocity dispersion. Any planetesimal disc must have survive...
متن کاملLong-lived neutralino NLSPs
We investigate the collider signatures of heavy, long-lived, neutral particles that decay to charged particles plus missing energy. Specifically, we focus on the case of a neutralino NLSP decaying to Z and gravitino within the context of General Gauge Mediation. We show that a combination of searches using the inner detector and the muon spectrometer yields a wide range of potential early LHC d...
