The Feyn-Structure of Yangian Symmetry
Florian Loebbert, Harshad Mathur
Yangian-type differential operators are shown to constrain Feynman integrals beyond the restriction to integrable graphs. In particular, we prove that all position-space Feynman di…
Aharonov-Bohm Radiation of Fermions
Yi-Zen Chu, Harsh Mathur, Tanmay Vachaspati
We analyze Aharonov-Bohm radiation of charged fermions from oscillating solenoids and cosmic strings. We find that the angular pattern of the radiation has features that differ sig…
Aharonov-Bohm Radiation
Katherine Jones-Smith, Harsh Mathur, Tanmay Vachaspati
A solenoid oscillating in vacuum will pair produce charged particles due to the Aharonov-Bohm (AB) interaction. We calculate the radiation pattern and power emitted for charged sca…
Relativistic Non-Hermitian Quantum Mechanics
Katherine Jones-Smith, Harsh Mathur
We develop relativistic wave equations in the framework of the new non-hermitian quantum mechanics. The familiar Hermitian Dirac equation emerges as an exact result of…
A New Class of non-Hermitian Quantum Hamiltonians with PT Symmetry
Katherine Jones-Smith, Harsh Mathur
In a remarkable development Bender and coworkers have shown that it is possible to formulate quantum mechanics consistently even if the Hamiltonian and other observables are not He…
Quantized Non-Abelian Monopoles on S^3
Irit Maor, Harsh Mathur, Tanmay Vachaspati
A possible electric-magnetic duality suggests that the confinement of non-Abelian electric charges manifests itself as a perturbative quantum effect for the dual magnetic charges.…
Zero modes on cosmic strings in an external magnetic field
Francesc Ferrer, Harsh Mathur, Tanmay Vachaspati +1
A classical analysis suggests that an external magnetic field can cause trajectories of charge carriers on a superconducting domain wall or cosmic string to bend, thus expelling ch…
