On zeros of exponential polynomials and quantum algorithms
Yoshitaka Sasaki
We calculate the zeros of an exponential polynomial of some variables by a classical algorithm and quantum algorithms which are based on the method of van Dam and Shparlinski, they…
Searching the Inclusive Lepton + Photon + Missing ET + b-quark Signature for Radiative Top Quark Decay and Non-Standard-Model Processes
CDF Collaboration, T. Aaltonen
In a search for new phenomena in a signature suppressed in the standard model of elementary particles (SM), we compare the inclusive production of events containing a lepton, a pho…
Geometric quantum gates in liquid-state NMR based on a cancellation of dynamical phases
Yukihiro Ota, Yoshito Goto, Yasusi Kondo +1
A proposal for applying non-adiabatic geometric phases to quantum computing, called the double-loop method [S.-L. Zhu and Z. D. Wang, Phys. Rev. A {\bf 67}, 022319 (2003)], is demo…
Thermodynamics of Black Holes in Horava-Lifshitz Gravity
Rong-Gen Cai, Li-Ming Cao, Nobuyoshi Ohta
By using the canonical Hamiltonian method, we obtain the mass and entropy of the black holes with general dynamical coupling constant in Hoř ava-Lifshitz Gravity. Regardless of…
Dynamics of intersecting brane systems -- Classification and their applications --
Kei-ichi Maeda, Nobuyoshi Ohta, Kunihito Uzawa
We present dynamical intersecting brane solutions in higher-dimensional gravitational theory coupled to dilaton and several forms. Assuming the forms of metric, form fields, and di…
Dust detection by the wave instrument on STEREO: nanoparticles picked up by the solar wind?
N. Meyer-Vernet, M. Maksimovic, A. Czechowski +7
The STEREO/WAVES instrument has detected a very large number of intense voltage pulses. We suggest that these events are produced by impact ionisation of nanoparticles striking the…
