Condition", Physical Review Letters 61 (1988): 1446
 It is argued that, if the laws of physics permit an advanced
civilization to create and maintain a wormhole in space for interstellar
travel, then that wormhole can be converted into a time machine with which
causality might be violatable. Whether wormholes can be created and maintained
entails deep, illunderstood issues about cosmic censorship, quantum gravity,
and quantum field theory, including the question of whether field theory
enforces an averaged version of the weak energy condition.

 NANDI, K. K.; ALAM, S. M. K., "Stringy Wormholes ", General
Relativity and Gravitation, V30, p1331 (1998)
 The possibility of static wormhole solutions in the string modified
gravity is examined. It turns out that ``practically traversable" wormholes
are not available in the two types of solutions considered. Interestingly,
these two solutions display exactly opposite wormhole features.
 XIAO, XINGGUO; CARR, B. J.; LIU, LIAO, "Wormholes in Vacuum BransDicke
Theory", General Relativity and Gravitation, V28, p1377 (1996)
 We present a Euclidean wormhole solution in vacuum BransDicke theory,
which is different from that obtained by Accetta et al. This wormhole appears
to have the feature that its throat dimension increases linearly with
Euclidean cosmic time, although this increase may not be measurable. It also
requires a negative BransDicke parameter W
 SHEN, YOUGEN, "Quantum wormhole with conformal scaler field", Acta
Astronomica Sinica, v34, no.2, p152 (1993)
 Using the HartleHawking method, we discuss the quantum wormhole with
conformal scatter field. The corresponding WheelerDe Witt equation was
derived, and the wave function of the wormhole calculated. The wormhole's wave
function we obtained is the product of double harmonic solutions. After
analyzing the wormhole's wave function, we found that the probability density
of the wormhole equals appearing at a = 0, and that the minimal radius of the
ground state of the wormhole is on the planck scale. Analyzing the wormhole's
wave function also reveals that the wormhole was likely be piled at
j = 0
 HOCHBERG, DAVID; KEPHART, THOMAS W., "Wormhole cosmology and the
horizon problem", Physical Review Letters, v70, no.18, p2665 (1993)
 We construct an explicit class of dynamic Lorentzian wormholes
connecting FriedmanRobertsonWalker spacetimes. These wormholes can allow twoway
transmission of signals between spatially separated regions of spacetime and
could permit such regions to come into thermal contact. The cosmology of a
network of early Universe wormholes is discussed
 SHEN, YOUGEN; TAN, ZHENQIANG; WANG, YOUNGJIU, "Wormholes and the
fermions field", Acta Astronomica Sinica, v33, no.2, p. 146.(1992)
 The concept of a wormhole is briefly discussed. A wormhole model with a
coupled fermionic field is then presented. The governing equations are derived,
and solutions are obtained in analytical form.
 WANG, JIN, " Two KaluzaKlein wormhole solutions", Astrophysics and
Space Science, v189, no.1, p5, Mar (1992)
 Tendimensional supergravity models and monople models are examined
analytically to obtain wormhole solutions which relate to the tunneling
process. The S1 x SN x SM topology is used as the framework for the model of
tendimensional supergravity, and a FreundRubintype spontaneous
compactification is used to derive the wormhole solution in D = 1 + N + M
dimensions. Two asymptotic regions are connected by the wormhole solution, and
the solution can be interpreted in terms of the tunneling between regions in
quantum cosmology.
 HAWKING, S. W.,"The alpha parameters of wormholes", Physica Scripta,
vol.T36, p222 (1991)
 The formulation of wormholes for calculating observations at low
energies can be interpreted as quantum theory decomposing into noninteracting
super selection sectors labelled by different values of effective coupling
constants, called the alpha parameters. This paper examines the interpretation
of the alpha parameters, and investigates whether wormholes just give rise to
a classical degree of uncertainty in the effective coupling constants. The
argument that one can replace wormholes by effective interactions by
considering quantum field theories in one and two dimensions, in which the
topology is not fixed in advance, is examined. These theories are Feynman
diagrams and string theory, which exhibit many of the same features as
wormholes; they have the great advantage of being well defined, and they can
be evaluated exactly. It is shown that the alpha parameters are different
modes of a single quantum field. This alpha field is a field on the superspace
of the theory, in other words, a third quantized field.
 CHOI, KIWOON; HOLMAN, R., "Wormholes and PecceiQuinn symmetries"
Physical Review Letters, vol. 64, Jan. 8, 1990, p. 131.
 Consideratin is given to the complementary roles of wormholes and
PecceiQuinn (1977) symmetries in solving the strong CP problem. It is shown
that PecceiQuinn symmetries provide a wormhole parameter that couples only to
the QCD anomaly. This makes it possible to implement the wormhole solution to
the strong CP problem constructed by Grinstein and Wise (1988) and Preskill
(1989).

wormholes", Classical and Quantum Gravity, vol. 6, Dec. 1, 1989, p. 1839
 The Euclidian Einstein equations with a cosmological constant and a
conformally coupled scalar field are solved, taking the metric to be of the
RobertsonWalker type. In the case l = 0, solutions
are found which represent a wormhole connecting two asymptotically flat
Euclidian regions. In the case l greater than 0,
the solutions represent tunneling from a small Tolmanlike universe to a large
RobertsonWalker universe.
 LEE, KIMYEONG "Wormholes and Goldstone bosons", Physical Review
Letters, vol. 61, July 18, 1988, p. 263
 The quantum theory of a complex scalar field coupled to gravity is
considered. A formalism for the semiclassical approach in Euclidean time is
developed and used to study wormhole physics. The conserved global charge
plays an essential role. Wormhole physics turns on only after the symmetry is
spontaneously broken. An effective selfinteraction for Goldstone bosons due
to wormholes is shown to be a cosine potential, whose vacuum energy will be
reduced by the cosmic expansion. Some implications and questions are discussed.
