Preparing Schrödinger cat states in a microwave cavity using a neural network

Hector Hutin, Pavlo Bilous, Chengzhi Ye +8

Scaling up quantum computing devices requires solving ever more complex quantum control tasks. Machine learning has been proposed as a promising approach to tackle the resulting ch…

Tunneling-induced fractal transmission in Valley Hall waveguides

Tirth Shah, Florian Marquardt, Vittorio Peano

The Valley Hall effect provides a popular route to engineer robust waveguides for bosonic excitations such a photons and phonons. The almost complete absence of backscattering in m…

Topologically Protected Transport in Engineered Mechanical Systems

Tirth Shah, Christian Brendel, Vittorio Peano +1

Mechanical vibrations are being harnessed for a variety of purposes and at many length scales, from the macroscopic world down to the nanoscale. The considerable design freedom in…

Observing polarization patterns in the collective motion of nanomechanical arrays

Juliane Doster, Tirth Shah, Thomas Fösel +2

In recent years, nanomechanics has evolved into a mature field, with wide-ranging impact from sensing applications to fundamental physics, and it has now reached a stage which enab…

Tunneling in the Brillouin Zone: Theory of Backscattering in Valley Hall Edge Channels

Tirth Shah, Florian Marquardt, Vittorio Peano

A large set of recent experiments has been exploring topological transport in bosonic systems, e.g. of photons or phonons. In the vast majority, time-reversal symmetry is preserved…

Perturbation theory of nearly spherical dielectric optical resonators

Julius Gohsrich, Tirth Shah, Andrea Aiello

Dielectric spheres of various sizes may sustain electromagnetic whispering-gallery modes resonating at optical frequencies with very narrow linewidths. Arbitrary small deviations f…

Topological phonon transport in an optomechanical system

Hengjiang Ren, Tirth Shah, Hannes Pfeifer +4

Recent advances in cavity-optomechanics have now made it possible to use light not just as a passive measuring device of mechanical motion, but also to manipulate the motion of mec…

Occasional uncoupling overcomes measure desynchronization

Anupam Ghosh, Tirth Shah, Sagar Chakraborty

Owing to the absence of the phase space attractors in the Hamiltonian dynamical systems, the concept of the identical synchronization between the dissipative systems is inapplicabl…

Finding Hannay angle in dissipative oscillatory systems via conservative perturbation theory

Rohitashwa Chattopadhyay, Tirth Shah, Sagar Chakraborty

Usage of a Hamiltonian perturbation theory for a nonconservative system is counterintuitive and in general, a technical impossibility by definition. However, the time-independent d…

Conservative perturbation theory for nonconservative systems

Tirth Shah, Rohitashwa Chattopadhyay, Kedar Vaidya +1

In this paper, we show how to use canonical perturbation theory for dissipative dynamical systems capable of showing limit cycle oscillations. Thus, our work surmounts the hitherto…
