Efficient excitation of nonlinear phonons via chirped mid-infrared pulses: induced structural phase transitions
A. P. Itin, M. I. Katsnelson
Nonlinear phononics play important role in strong laser-solid interactions. We discuss nonlinear dynamical protocols which allow for efficient excitation and control of nonlinear p…
Dynamics of fermions in an amplitude modulated lattice
Tomotake Yamakoshi, Shinichi Watanabe, Shun Ohgoda +1
We study dynamics of fermions loaded in an optical lattice with a superimposed parabolic trap potential. In the recent Hamburg experiments [J.Heinze et.al., Phys. Rev. Lett. 110, 0…
Effective Hamiltonians for fastly driven tight-binding chains
A. P. Itin, A. I. Neishtadt
We consider a single particle tunnelling in a tight-binding model with nearest-neighbour couplings, in the presence of a periodic high-frequency force. An effective Hamiltonian for…
Effective Hamiltonians for fastly driven many-body lattice systems
A. P. Itin, M. I. Katsnelson
We consider 1D lattices described by Hubbard or Bose-Hubbard models, in the presence of periodic high-frequency perturbations, such as uniform ac force or modulation of hopping coe…
Intrinsic Photoconductivity of Ultracold Fermions in Optical Lattices
J. Heinze, J. S. Krauser, N. Fläschner +6
We report on the experimental observation of an analog to a persistent alternating photocurrent in an ultracold gas of fermionic atoms in an optical lattice. The dynamics is induce…
Directed transport in a classical lattice with a high-frequency driving
A. P. Itin, A. I. Neishtadt
We analyze the dynamics of a classical particle in a spatially periodic potential under the influence of a periodic in time uniform force. It was shown in [S.Flach, O.Yevtushenko,…
