Solving the multi-site and multi-orbital Dynamical Mean Field Theory using Density Matrix Renormalization [PDF]
, 2017 We implement an efficient numerical method to calculate response functions of complex impurities based on the Density Matrix Renormalization Group (DMRG) and use it as the impurity-solver of the Dynamical Mean Field Theory (DMFT).

Free evolution of an incoherent mixture of states: a quantum mechanical approach to the van Cittert-Zernike theorem [PDF]
, 2019 We study the time evolution of an incoherent mixture of quantum states and demonstrate, in very simple terms, a quantum mechanical equivalent of van Cittert–Zernike theorem, which can be easily explained to Quantum Physics students with a basic knowledge

Critical region of long-range depinning transitions [PDF]
, 2018 The depinning transition of elastic interfaces with an elastic interaction kernel decaying as 1/rd+σ is characterized by critical exponents which continuously vary with σ.

Analysis of motion of solid hydrogen tracer particles in oscillating superfluid flows [PDF]
, 2014 We have developed a relatively simple cryostat which allows us to image turbulent flows in superfluid helium at temperatures below 2 K, using frozen H2 particles.

Width of the charge-transfer peak in the SU(N) impurity Anderson model and its relevance to nonequilibrium transport [PDF]
, 2018 We calculate the width 2ΔCT and intensity of the charge-transfer peak (the one lying at the on-site energy Ed) in the impurity spectral density of states as a function of Ed in the SU(N) impurity Anderson model (IAM).
