Sculpt

A term that is nearly synonymous with complex numbers or functions is their phase. The rising preoccupation with the wave function phase in the last few decades is beyond doubt, to the extent that the importance of phases has of late become comparable to that of the moduli. (We use Dirac s terminology [7], which writes a wave function by a set of coefficients, the amplitudes, each expressible in terms of its absolute value, its modulus, and its phase. ) There is a related growth of literatm e on interference effects, associated with Aharonov-Bohm and Berry phases [8-14], In parallel, one has witnessed in recent years a trend to construct selectively and to manipulate wave functions. The necessary techifiques to achieve these are also anchored in the phases of the wave function components. This bend is manifest in such diverse areas as coherent or squeezed states [15,16], elecbon bansport in mesoscopic systems [17], sculpting of Rydberg-atom wavepackets [18,19], repeated and nondemolition quantum measurements [20], wavepacket collapse [21], and quantum computations [22,23], Experimentally, the determination of phases frequently utilizes measurement of Ramsey fringes [24] or similar" methods [25]. [Pg.96]

Occurs in the Rhode Island hamlet of Eastwick. Wonderful powers have descended upon Jane, Sukie, and Alexandra now that their husbands are out of the way Alexandra sculpts and creates thunderstorms, Jane plays the cello and can fly through the air, Sukie writes a gossip column and turns milk into cream. Their snug little coven takes on new and more malignant life when a dark, burly and apparently wealthy stranger, Darryl Van Horne, arrives in town he refurbishes the old Lenox mansion, and sets up an alchemist s lab. .. [Pg.713]

The creation of nanoscale sandwiches of compound semiconductor heterostructures, with gradients of chemical composition that are precisely sculpted, could produce quantum wells with appropriate properties. One can eventually think of a combined device that incorporates logic, storage, and communication for computing—based on a combination of electronic, spintronic, photonic, and optical technologies. Precise production and integrated use of many different materials will be a hallmark of future advanced device technology. [Pg.133]

The forces that sculpt the evolution of specialization among marine herbivores have been explored in terrestrial systems for decades but only recently with marine systems (Hay and Fenical 1988 Trowbridge 1991a Hay 1992 Sotka et al. 1999 Poore et al. 2000 Krug 2001 Trowbridge and Todd 2001 Cruz-Rivera and Paul... [Pg.216]

He stared at me for a long moment, as if assessing my sanity or lack of, but in the end he led me inside. Billows of fog swirled in with us. The great sculpted cavern was as cold and deserted as the world outside, lit by a few faint candles at the far end that seemed no brighter than fluttering stars. Its austere and awesome beauty was invisible, but the very stillness seemed holy I could hear the silence as if it were built into the stone. [Pg.124]

The Egyptians used the symbolism of the four sons and the four goddesses to orientate magical structures to the cardinal directions. In numerous tombs the vital organs of a mummy were removed and placed in jars, each sculpted with the appropriate head of the son who protected those organs. These jars were arranged in square... [Pg.30]
