| contents | In this work, we investigate the violation of Lorentz symmetry through the Casimir effect. The Casimir effect is one of the most intriguing aspects of modern physics, representing a macroscopic quantum-origin force between two neutral conducting surfaces, and it stands as a triumph of Quantum Field Theory. Here, we examine the Casimir effects associated with a massive fermionic quantum field confined in the region between two large and parallel plates within the Horava-Lifshitz framework of Lorentz symmetry violation. To calculate the Casimir energy and consequently the Casimir pressure, we impose a MIT bag boundary condition on two plates, compatible with the higher-order derivative term in the modified Dirac equation. Our results indicate a strong influence of Lorentz violation on the Casimir effect. We observe that the Casimir energy is affected, both in intensity and sign, potentially exhibiting repulsive or attractive force between the plates, depending on the critical exponent associated with the Horava-Lifshitz formalism. |
