Quantum logic spectroscopy (QLS) enables optical frequency metrology with atomic and molecular ions that are promising for novel optical clocks and tests of fundamental physics but lack optical E1 transitions for laser cooling and state detection. QLS is based on two-ion crystals, which necessitate the use of linear Paul traps. Imperfections in trap geometry due to manufacturing, assembly, or cryogenic cool-down can cause axial micromotion, which cannot be compensated for and has been identified as a leading systematic effect in a previous trap design. Addressing this limitation, we report on simulation-based studies of a new linear Paul trap, based on a monolithic design by PTB and LUH. We explore an asymmetric and symmetric drive that can be provided by a superconducting YBCO step-up resonator. Additional features of the novel design include independent DC electrodes to allow mode coupling via parametric modulation of the trapping field. These design enhancements offer significant potential for improving the accuracy of future quantum logic clocks.
