Many-body quantum Monte Carlo study of 2D materials: cohesion and band gap in single-layer phosphorene
Tobias Frank, Rene Derian, Kamil Tokar +3
Quantum Monte Carlo (QMC) is applied to obtain the fundamental (quasiparticle) electronic band gap, , of a semiconducting two-dimensional (2D) phosphorene whose optical and el…
Quantum Monte Carlo study of one-dimensional transition metal organometallic cluster systems and their suitability as spin filters
L. Horváthová, R. Derian, L. Mitas +1
We present calculations of electronic and magnetic structures of vanadium-benzene multidecker clusters VBz ( = 1 - 3) using advanced quantum Monte Carlo methods. T…
Quantum Monte Carlo for Noncovalent Interactions: An Efficient Protocol Attaining Benchmark Accuracy
Matúš Dubecký, René Derian, Petr Jurečka +3
Reliable theoretical predictions of noncovalent interaction energies, which are important e.g. in drug-design and hydrogen-storage applications, belong to longstanding challenges o…
Generalized DMPK equation for strongly localized regime - numerical solution
J Brndiar, R. Derian, P. Markos
Generalized Dorokhov-Mello-Pereyra-Kumar (GDMPK) equation [K. A. Muttalib and J. R. Klauder, Phys. Rev. Lett. {\bf 82}, 4272 (1999)] has been proposed for the description of the el…
Modulation of Local Magnetization in two-dimensional Axial-Next-Nearest-Neighbor Ising model
Rene Derian, Andrej Gendiar, Tomotoshi Nishino
The axial next-nearest-neighbor Ising model is studied in two dimensions at finite temperature using the density matrix renormalization group. The model exhibits phase transition o…
Product Wave Function Renormalization Group: construction from the matrix product point of view
Kouji Ueda, Tomotoshi Nishino, Kouichi Okunishi +3
We present a construction of a matrix product state (MPS) that approximates the largest-eigenvalue eigenvector of a transfer matrix T, for the purpose of rapidly performing the inf…
