Enhanced eigenvector sensitivity and algebraic classification of sublattice-symmetric exceptional points
Kang Yang, Ipsita Mandal
Exceptional points (EPs) are degeneracy of non-Hermitian Hamiltonians, at which the eigenvalues, along with their eigenvectors, coalesce. Their orders are given by the Jordan decom…
Role of parasitic interactions and microwave crosstalk in dispersive control of two superconducting artificial atoms
Alan C. Santos
In this work we study the role of parasitic interactions and microwave crosstalk in a system of two superconducting artificial atoms interacting via a single-mode coplanar waveguid…
Gauge independent description of Aharonov-Bohm Effect
Xiang Li, Thors Hans Hansson, Wei Ku
The Aharonov-Bohm (AB) effect is a pure quantum effect that implies a measurable phase shift in the wave function for a charged particle that encircles a magnetic flux located in a…
Dimension towers of SICs. II. Some constructions
Ingemar Bengtsson, Basudha Srivastava
A SIC is a maximal equiangular tight frame in a finite dimensional Hilbert space. Given a SIC in dimension , there is good evidence that there always exists an aligned SIC in di…
