Rapidity-Coupled Spin Dynamics in Pulsed Laser Fields from Physics-Informed Neural Networks
N. S. Akintsov, A. P. Nevecheria, S. N. Andreev +1
Carrier-envelope-phase (CEP) stabilized few-cycle pulses make the sub-cycle field structure a control parameter for laser-driven polarized electron sources, yet spin solvers for su…
Casimir-electrostatic pull-in in nanoelectromechanical actuators: Differentiable design sensitivities and the damping-dependent collapse boundary
N. S. Akintsov, A. P. Nevecheria, S. N. Andreev +1
Nanoelectromechanical actuators operating at sub-100-nm gaps collapse through a pull-in instability set by competing electrostatic and Casimir forces. The quasi-static fold that bo…
Net electron spin rotation in a plane-wave pulse: Holonomy set by the anomalous magnetic moment
N. S. Akintsov, A. P. Nevecheria, S. N. Andreev +1
We compute the spin rotation that survives after a relativistic electron has crossed a plane-wave laser pulse of finite duration. In the interaction picture built on the exact $g=2…
Acoustic Firewalls: Analogue Gravity Perspective on the AMPS Paradox
Nikolay S. Akintsov, Artyom P. Nevecheria, Stepan N. Andreev +1
The monogamy of quantum entanglement, applied by Almheiri-Marolf-Polchinski-Sully (AMPS) to black holes, obstructs a smooth horizon vacuum after the Page time. We transcribe this a…
