Probing Lattice Dynamics in Real-Space and Real-Time
Navdeep Rana
The coherent lattice vibrations significantly impact physical and chemical processes in solids, such as heat transfer, displacive phase transitions, and thermal conductivity. Thus,…
Probing lattice fluctuations using solid-state high-harmonic spectroscopy
Lance Hatch, Navdeep Rana, Shoushou He +8
Solid-state high-harmonic spectroscopy allows the study of strongly driven ultrafast electron dynamics. Microscopically, high harmonics are generated by strong-laser-field accelera…
Disorder to Order Transition in 1D non-reciprocal Cahn-Hilliard Model
Navdeep Rana, Ramin Golestanian
We present the phenomenology of the one dimensional non-reciprocal Cahn Hilliard model for varying non-reciprocity and different boundary conditions. At small , a pertur…
Efficient Pseudo-spectral Algorithms for Statistical Field Theories
Martin Kjøllesdal Johnsrud, Navdeep Rana
We present stochastic variants of the exponential time differencing schemes for stiff stochastic differential equations. We derive three explicit schemes that offer better stabilit…
Non-reciprocal mixtures in suspension: the role of hydrodynamic interactions
Giulia Pisegna, Navdeep Rana, Ramin Golestanian +1
The collective chasing dynamics of non-reciprocally coupled densities leads to stable travelling waves which can be mapped to a model for emergent flocking. In this work, we couple…
