Quaternionic fermionic field
Sergio Giardino
The second quantization of the quaternionic fermionic field is undertaken using the real Hilbert space approach to quaternionic quantum mechanics ($\mathbbm H$QM). The solution res…
Four-dimensional conformal field theory using quaternions
Sergio Giardino
We build a four-dimensional quaternion-parametrized conformal field theory (QCFT) using quaternion holomorphic functions as the generators of quaternionic conformal transformations…
Tunnelling of Pulsating Strings in Deformed Minkowski Spacetime
Sergio Giardino, Victor Rivelles
Using the WKB approximation we analyse the tunnelling of a pulsating string in deformed Minkowski spacetime.
The Static String
Sergio Giardino
In this article the quantum fluctuation of a rigid and static string is reported to be identical to a free quantum particle. Solutions similar to this static string have already be…
Semi-classical strings in dimensional backgrounds
Sergio Giardino
This study analyzes the geometrical relationship between a classical string and its semi-classical quantum model. From an arbitrary dimensional geometry, a specific ansatz…
Divergent energy strings in with three angular momenta
Sergio Giardino
In this paper, novel solutions for strings with three angular momenta in geometry are presented; the divergent energy limit and the corresponding conserved charg…
Pulsating Strings in Lunin-Maldacena Backgrounds
Sergio Giardino, Victor Rivelles
We consider pulsating strings in Lunin-Maldacena backgrounds, specifically in deformed Minkowski spacetime and deformed AdS_5xS^5. We find the relation between the energy and the o…
Classical strings in with three angular momenta
Sergio Giardino, Hector L. Carrión
In this paper, rotating strings in three directions of geometry are studied; its divergent energy limit, and conserved charges are also determined. An…
