Rec.nt developments.in the s.udy of ultrac.ld Rydberg gas.s.demand an adwanc.d level of experimental s.phis.ic.tion, in whic. high atomic.and optic.l dens.ties.mus. be c.mbined with exc.llent c.ntrol of external fields.and s.ns.tive Rydberg atom detec.ion. We des.0}ibe a tailored experimental s.s.em us.d to produc. and s.udy Rydberg-interac.ing atoms.exc.ted from dens. ultrac.ld atomic.gas.s. The experiment has.been optimized for fas. duty c.c.es.us.ng a high flux c.ld atom s.urc. and a three beam optic.l dipole trap. The latter enables.tuning of the atomic.dens.ty and temperature over s.veral orders.of magnitude, all the way to the Bos.--Eins.ein c.ndens.tion trans.tion. An elec. trode s.ruc.ure s.rrounding the atoms.allows.for prec.s. c.ntrol over elec.ric.fields.and s.ngle-partic.e s.ns.tive field ionization detec.ion of Rydberg atoms. We review two experiments.whic. highlight the influenc. of s.rong Rydberg---Rydberg interac.ions.on different many-body s.s.ems. Firs., the Rydberg bloc.ade effec. is.us.d to pre-s.ruc.ure an atomic.gas.prior to its.s.ontaneous.evolution into an ultrac.ld plas.a. s.c.nd, hybrid s.ates.of photons.and atoms.c.lled dark-s.ate polaritons.are s.udied. By looking at the s.atis.ic.l dis.ribution of Rydberg exc.ted atoms.we reveal c.rrelations.between dark-s.ate polaritons. Thes. experiments.will ultimately provide a deeper unders.anding of many-body phenomena in s.rongly-interac.ing regimes. inc.uding the s.udy of s.rongly-c.upled plas.as.and interfac.s.between atoms.and light at the quantum level.

研究复杂制动环境对修复熔覆层服役性能的影响,对提高列车轮轨系统抵御极端恶劣环境的能力具有重要意义。本文针对火车车轮踏面局部损伤问题,利用激光熔覆修复技术在损伤处制备316L不锈钢涂层。采用Ms.HT1000高温磨损试验机进行磨损实验。然后,分析不同制动条件对修复试样在室温和高温下摩擦磨损性能的影响。

关键词：激光修复铁路车轮局部损伤磨损实验车轮踏面磨损试验机服役性能踏面制动
