Our results concern the transition of a quantum string through the singularity of the compactified Milne (CM) space. We restrict our analysis to the string winding around the compact dimension (CD) of spacetime. The CD undergoes contraction to a point followed by re-expansion. We demonstrate that both the classical and quantum dynamics of the considered string are well defined. Most of the presently available calculations strongly suggest that the singularity of a time-dependent orbifold is… 

Excited states of a string in a time-dependent orbifold

We present analytical results on the propagation of a classical string in nonzero modes through the singularity of the compactified Milne space. We restrict our analysis to a string winding around

Modelling cosmological singularity with compactified Milne space

Recent developments in observational cosmology call for understanding the nature of the cosmological singularity (CS). Our work proposes modelling the vicinity of CS by a time dependent orbifold

Propagation of extended objects across singularity of time dependent orbifold

In this paper we argue that the compactified Milne space is a promising model of the cosmological singularity. It is shown that extended objects like strings propagate in a well‐defined manner across

Dirac quantization of membrane winding uniformly in time dependent orbifold

We present quantum theory of a membrane propagating in the vicinity of a time dependent orbifold singularity. The dynamics of a membrane, with the parameters space topology of a torus, winding

Milne universe, tachyons, and quantum group

We analyze the spectrum of the bosonic and superstring on the orbifold of the space-time by a boost, leading to the cosmological singularity. We show that the modular invariance leads to the spectrum

Comments on Cosmological Singularities in String Theory

We compute string scattering amplitudes in an orbifold of Minkowski space by a boost, and show how certain divergences in the four point function are associated with graviton exchange near the

Time‐dependent orbifolds and string cosmology

In these lectures, we review the physics of time-dependent orbifolds of string theory, with particular attention to orbifolds of three-dimensional Minkowski space. We discuss the propagation of free

The (n + 1)-dimensional Milne universe with extra free directions is used to construct simple FRW cosmological string models in four dimensions, describing expansion in the presence of matter with p=

Strings in an electric field, and the Milne Universe

Arguably the simplest model of a cosmological singularity in string theory, the Lorentzian orbifold 1,1/boost is known to lead to severe divergences in scattering amplitudes of untwisted states,

Strings in Time-Dependent Orbifolds

We continue and extend our earlier investigation ``Strings in a Time-Dependent Orbifold'' (hep-th/0204168). We formulate conditions for an orbifold to be amenable to perturbative string analysis and

M theory model of a big crunch/big bang transition

We consider a picture in which the transition from a big crunch to a big bang corresponds to the collision of two empty orbifold planes approaching each other at a constant nonrelativistic speed in a

Instability of spacelike and null orbifold singularities

Time dependent orbifolds with spacelike or null singularities have recently been studied as simple models of cosmological singularities. We show that their apparent simplicity is an illusion: the

We present classical and quantum dynamics of a test particle in the compactified Milne space. Background spacetime includes one compact space dimension undergoing contraction to a point followed by
