Quantum vacuum interaction between two sine-Gordon kinks
M. Bordag, J. M. Munoz-Castaneda
We calculate the quantum vacuum interaction energy between two kinks of the sine-Gordon equation. Using the --formula, the problem is reduced to the known formulas for quantu…
Wick rotation for quantum field theories on degenerate Moyal space(-time)
Harald Grosse, Gandalf Lechner, Thomas Ludwig +1
In this paper the connection between quantum field theories on flat noncommutative space(-times) in Euclidean and Lorentzian signature is studied for the case that time is still co…
On the corrections beyond proximity force approximation (PFA)
L. P. Teo, M. Bordag, V. Nikolaev
We recalculate the first analytic correction beyond PFA for a sphere in front of a plane for a scalar field and for the electromagnetic field. We use the method of Bordag and Nikol…
Baxter operators for arbitrary spin II
D. Chicherin, S. Derkachov, D. Karakhanyan +1
This paper presents the second part of our study devoted to the construction of Baxter operators for the homogeneous closed XXX spin chain with the quantum space carrying infinite…
Baxter operators for arbitrary spin
D. Chicherin, S. Derkachov, D. Karakhanyan +1
We construct Baxter operators for the homogeneous closed spin chain with the quantum space carrying infinite or finite dimensional representations. All alg…
