Since the recent experimental realization of synthetic Rashba spin-orbit coupling paved a new avenue for exploring and engineering topological phases in ultracold atoms, a precise, solid detection of Berry phase has been desired for unequivocal characterization of system topology. Here, we propose a scheme to conduct momentum-space Aharonov-Bohm interferometry in a Rashba spinorbit coupled Bose...

Diabolical points (spectral degeneracies) can naturally occur in spectra of two-dimensional quantum systems and classical wave resonators due to simple symmetries. Geometric Berry phase is associated with these spectral degeneracies. Here, we demonstrate a diabolical point and the corresponding Berry phase in the spectrum of hybrid light-matter quasiparticles-exciton-polaritons in semiconductor...

Applications of glass nanostructuring for manipulation of orbital angular momentum are reviewed. The phase control is implemented via the combination of form birefringence and Pancharatnam-Berry phase.

We present the first measurements of the Berry phase in a superconducting Cooper pair pump. A fixed amount of Berry phase is accumulated to the quantum-mechanical ground state in each adiabatic pumping cycle, which is determined by measuring the charge passing through the device. The dynamic and geometric phases are identified and measured quantitatively from their different response when pumpi...

Topological phases can arise as a system undergoes a cyclic motion. The phase accumulated by a charge encircling a magnet ic fluxon is the A h a r o n o v B o h m (AB) effect [ 1 ] (AB) , or, for a magnetic moment encircling a line of charge, the A h a r o n o v C a s h e r (AC) effect [2] . Cyclic mot ion of a state in Hi lber t space can also give rise to the Berry phase [3] . The lat ter pha...

We consider phase-coherent transport through ballistic and diffusive two-dimensional hole systems based on the Kohn-Luttinger Hamiltonian. We show that intrinsic heavy-hole-light-hole coupling gives rise to clear-cut signatures of an associated Berry phase in the weak localization which renders the magnetoconductance profile distinctly different from electron transport. Nonuniversal classical c...

In many classical and quantum systems described by an effective non-Hermitian Hamiltonian, spectral phase transitions, from entirely real-energy spectrum to a complex spectrum, can be observed as parameter in the system is increased above critical value. A paradigmatic example provided possessing parity-time ($\mathcal{PT}$) symmetry, where energy remains real unbroken $\mathcal{PT}$ while tran...

We formulate the problem of electron transport through a single-molecule magnet (SMM) in the Coulomb blockade regime taking into account topological interference effects for the tunneling of the large spin of a SMM. The interference originates from spin Berry phases associated with different tunneling paths. We show that, in the case of incoherent spin states, it is essential to place the SMM b...
