The quantum vibrations in atoms hold a miniature world of information. If scientists can accurately measure these atomic oscillations, and how they evolve over time, they can hone the precision of ato...
Time Reversal and Charge Conjugation in an Embedding Quantum Simulator
Charge Conjugation Embedding Quantum Simulator
2016/1/22
A quantum simulator is an important device that may soon outperform current classical computations. A basic arithmetic operation, the complex conjugate, however, is considered to be impossible to be i...
The utilization of time reversal symmetry in designing and implementing (quantum) optical experiments has become more and more frequent over the past years. We review the basic idea underlying time re...

We derive the parity- and time-reversal-violating nuclear interactions stemming from the QCD theta term and quark/gluon operators of effective dimension 6: quark electric dipole moments, quark and glu...

Penetration of nonquantized magnetic flux through a domain-wall bend in time-reversal symmetry broken superconductors
Penetration of nonquantized magnetic flux domain-wall superconductors

It has been proposed that the superconductivity of Sr2RuO4 is characterized by pairing that is
unconventional and, furthermore, spontaneously breaks time-reversal symmetry. However, one of
the key e...

We lay out an experiment to realize time-reversal invariant topological insulators in alkali atomic gases. We introduce an original method to synthesize a gauge field in the near-field of an atom-chip...
Controlled directed particle current despite time-reversal symmetry
Controlled directed particle current despite time-reversal symmetry
2010/10/21
Quantum ratchets are systems that exhibit asymptotic currents when they are driven by a time-periodic potential of zero mean if the proper spatio-temporal symmetries are broken. The current arises fro...
Chaotic instantons and enhancement of tunneling in kicked double-well system with time-reversal symmetry

2010/2/15
Chaotic instanton approach is used to describe dynamical tunneling in kicked double well system. Effective Hamiltonian for the kicked system is obtained using matrix expansion formula for operator exp...
