Thermal versus quantum fluctuations of optical-lattice fermions
(2012-03-29) - Journal articleWe show that, for fermionic atoms in a one-dimensional optical lattice, the fraction of atoms in doubly occupied sites is a highly nonmonotonic function of temperature. We demonstrate that this property persists even in ... -
Quantum order-by-disorder driven phase reconstruction in the vicinity of ferromagnetic quantum critical points
(2012-04-06) - Journal articleThe formation of new phases close to itinerant electron quantum critical points has been observed experimentally in many compounds. We present a unified analytical model that explains the emergence of new types of order ... -
Pressure study of nematicity and quantum criticality in Sr3Ru2O7 for an in-plane field
(2013-12-27) - Journal articleWe study the relationship between the nematic phases of Sr3Ru2O7 and quantum criticality. At ambient pressure, one nematic phase is associated with a metamagnetic quantum critical end point (QCEP) when the applied magnetic ... -
Ionization in atmospheres of brown dwarfs and extrasolar planets. V. Alfvén ionization
(2013-10-10) - Journal articleObservations of continuous radio and sporadic X-ray emission from low-mass objects suggest they harbor localized plasmas in their atmospheric environments. For low-mass objects, the degree of thermal ionization is insufficient ... -
Numerical investigation of passive optical sorting of plasmon nanoparticles
(2011-07-06) - Journal articleWe explore the passive optical sorting of plasmon nanoparticles and investigate the optimal wavelength and optimal beam shape of incident field. The condition for optimal wavelength is found by maximising the nanoparticle ...
