Approximating the chromatic polynomial is as hard as computing it exactly
Ferenc Bencs, Jeroen Huijben, Guus Regts
We show that for any non-real algebraic number such that or it is \textsc{\#P}-hard to compute a multiplicative (resp. additive) approximation to…
On the location of chromatic zeros of series-parallel graphs
Ferenc Bencs, Jeroen Huijben, Guus Regts
In this paper we consider the zeros of the chromatic polynomial of series-parallel graphs. Complementing a result of Sokal, showing density outside the disk , we show d…
Sampling from the low temperature Potts model through a Markov chain on flows
Jeroen Huijben, Viresh Patel, Guus Regts
In this paper we consider the algorithmic problem of sampling from the Potts model and computing its partition function at low temperatures. Instead of directly working with spin c…
Parallel electron-hole bilayer conductivity from electronic interface reconstruction
R. Pentcheva, M. Huijben, K. Otte +12
The perovskite SrTiO-LaAlO structure has advanced to a model system to investigate the rich electronic phenomena arising at polar interfaces. Using first principles calcula…
Magnetoresistance oscillations and relaxation effects at the SrTiO3-LaAlO3 interface
M. van Zalk, J. Huijben, A. J. M. Giesbers +8
We present low-temperature and high-field magnetotransport data on SrTiO3-LaAlO3 interfaces. The resistance shows hysteresis in magnetic field and a logarithmic relaxation as a fun…
Magnetic effects at the interface between nonmagnetic oxides
A. Brinkman, M. Huijben, M. van Zalk +7
The electronic reconstruction at the interface between two insulating oxides can give rise to a highly-conductive interface. In analogy to this remarkable interface-induced conduct…
