Aspects of Nonrelativistic Strings
Frontiers in Physics, 2022 We review recent developments on nonrelativistic string theory. In flat spacetime, the theory is defined by a two-dimensional relativistic quantum field theory with nonrelativistic global symmetries acting on the worldsheet fields.

Classical open string amplitudes from boundary string field theory
Journal of High Energy Physics, 2019 We calculate the corrections to the open string BRST charge in boundary string field theory and show that the expansion coefficients agree with the perturbative S-matrix to all orders.

SO(32) Spinors of Type I and Other Solitons on Brane-Antibrane Pair [PDF]
, 1998 We construct the SO(32) spinor state in weakly coupled type I string theory as a kink solution of the tachyon field on the D-string - anti-D-string pair and calculate its mass.

Space-Time Noncommutative Field Theories And Unitarity [PDF]
, 2000 We study the perturbative unitarity of noncommutative scalar field theories. Field theories with space-time noncommutativity do not have a unitary S-matrix. Field theories with only space noncommutativity are perturbatively unitary.

The ZZ annulus one-point function in non-critical string theory: A string field theory analysis
Journal of High Energy Physics, 2022 We compute the ZZ annulus one-point function of the cosmological constant operator in non-critical string theory, regulating divergences from the boundaries of moduli space using string field theory.

String theory or field theory? [PDF]
Physics-Uspekhi, 2002 The status of string theory is reviewed, and major recent developments - especially those in going beyond perturbation theory in the string theory and quantum field theory frameworks - are discussed. This analysis helps better understand the role and place of string theory in the modern picture of the physical world.

SYM Description of PP-wave String Interactions: Singlet Sector and Arbitrary Impurities [PDF]
, 2003 We study string interactions among string states with arbitrary impurities in the Type IIB plane wave background using string field theory. We reproduce all string amplitudes from gauge theory by computing matrix elements of the dilatation operator in a ...

INTERPOLATING STRING FIELD THEORIES [PDF]
Modern Physics Letters A, 1992 A minimal area problem imposing different length conditions on open and closed curves is shown to define a one-parameter family of covariant open-closed quantum string field theories. These interpolate from a recently proposed factorizable open-closed theory up to an extended version of Witten’s open string field theory capable of incorporating on ...

Gravitational Scattering Amplitudes and Closed String Field Theory in the Proper-Time Gauge
EPJ Web of Conferences, 2018 We construct a covariant closed string field theory by extending recent works on the covariant open string field theory in the proper-time gauge. Rewriting the string scattering amplitudes generated by the closed string field theory in terms of the ...

Half-String Approach to Closed String Field Theory [PDF]
, 1993 In this letter we present an operator formalism for Closed String Field Theory based on closed half-strings. Our results indicate that the restricted polyhedra of the classical non-polynomial string field theory, can be represented as traces of infinite ...
