Field-theory results for three-dimensional transitions with complex symmetries
Pasquale Calabrese, Andrea Pelissetto, Paolo Rossi +1
We discuss several examples of three-dimensional critical phenomena that can be described by Landau-Ginzburg-Wilson theories. We present an overview of field-theoretical resu…
Ferromagnetic resonant tunneling diodes as spin polarimeters and polarizers
Francesco Giazotto, Fabio Taddei, Rosario Fazio +1
A method for measuring the degree of spin polarization of magnetic materials based on spin-dependent resonant tunneling is proposed. The device we consider is a ballistic double-ba…
Simultaneous Measurement of the B0 Meson Lifetime and Mixing Frequency with B0 --> D*- l+ nu Decays
the BABAR Collaboration, B. Aubert
We measure the B0 lifetime τ_{B0} and the B0-B0bar oscillation frequency Δm_d with a sample of approximately 14,000 exclusively reconstructed B0 --> D*- l+ nu signal events, select…
Active suppression of dephasing in Josephson-junction qubits
Dmitri V. Averin, Rosario Fazio
Simple majority code correcting dephasing errors by encoding a qubit of information into physical qubits is studied quantitatively. We derive an equation for quasicontin…
Mathematical structure of the temporal gauge
J. Loeffelholz, G. Morchio, F. Strocchi
The mathematical structure of the temporal gauge of QED is critically examined in both the alternative formulations characterized by either positivity or regularity of the Weyl alg…
3-D Interacting CFTs and Generalized Higgs Phenomenon in Higher Spin Theories on AdS
L. Girardello, M. Porrati, A. Zaffaroni
We study a duality, recently conjectured by Klebanov and Polyakov, between higher-spin theories on AdS_4 and O(N) vector models in 3-d. These theories are free in the UV and intera…
