Analogy between a two-well Bose-Einstein condensate and atom diffraction
H. L. Haroutyunyan, G. Nienhuis
We compare the dynamics of a Bose-Einstein condensate in two coupled potential wells with atoms diffracting from a standing light wave. The corresponding Hamiltonians have an ident…
CUORE: A Cryogenic Underground Observatory for Rare Events
C. Arnaboldi, F. T. Avignone, J. Beeman +36
CUORE is a proposed tightly packed array of 1000 TeO2 bolometers, each being a cube 5 cm on a side with a mass of 760 g. The array consists of 25 vertical towers, arranged in a squ…
Long-range ferromagnetic dipolar ordering of high-spin molecular clusters
A. Morello, F. L. Mettes, F. Luis +5
We report the first example of a transition to long-range magnetic order in a purely dipolarly interacting molecular magnet. For the magnetic cluster compound Mn6O4Br4(Et2dbm)6, th…
Comment on 'Gravitating magnetic monopole in the global monopole spacetime'
A. Achucarro, J. Urrestilla
We point out a problem with the stability of composite (global-magnetic) monopoles recently proposed by J. Spinelly, U. de Freitas and E.R. Bezerra de Mello [Phys. Rev. D66, 024018…
Fermion zero modes in N=2 supervortices
A. Achucarro, A. C. Davis, M. Pickles +1
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. There…
Quantum Andreev map: A paradigm of quantum chaos in superconductivity
Ph. Jacquod, H. Schomerus, C. W. J. Beenakker
We introduce quantum maps with particle-hole conversion (Andreev reflection) and particle-hole symmetry, which exhibit the same excitation gap as quantum dots in the proximity to a…
