Casimir Force in Spacetimes with Torsion
M. W. AlMasri
We compute the Casimir force between perfectly conducting parallel plates in a spacetime endowed with constant axial torsion. Working within an effective field theory framework whe…

Remarks on Regular Approximations to the Robin Aharonov-Bohm Hamiltonian
Cesar R. de Oliveira
In the space , for Robin parameter , it is shown that there is a family of Schrödinger operators with penetrable toroidal solenoid and variable conductivity that…

Geometric Constraints on Quantum Gravity-Inspired Dispersion Relations
Gines R. Perez Teruel
Modified dispersion relations (MDRs) arise in many quantum-gravity approaches, often in non-polynomial or non-analytic form beyond the reach of effective field theory (EFT). Logari…
