      abstract     = {The blazar Mrk 501 ($z$ = 0.034) was observed at
                      very-high-energy (VHE, E $\gtrsim$ 100 GeV) gamma-ray
                      wavelengths during a bright flare on the night of 2014 June
                      23–24 (MJD 56832) with the H.E.S.S. phase-II array of
                      Cherenkov telescopes. Data taken that night by H.E.S.S. at
                      large zenith angle reveal an exceptional number of gamma-ray
                      photons at multi-TeV energies, with rapid flux variability
                      and an energy coverage extending significantly up to 20 TeV.
                      This data set is used to constrain Lorentz invariance
                      violation (LIV) using two independent channels: a temporal
                      approach considers the possibility of an energy dependence
                      in the arrival time of gamma-rays, whereas a spectral
                      approach considers the possibility of modifications to the
                      interaction of VHE gamma-rays with extragalactic background
                      light (EBL) photons. The non-detection of energy-dependent
                      time delays and the non-observation of deviations between
                      the measured spectrum and that of a supposed power-law
                      intrinsic spectrum with standard EBL attenuation are used
                      independently to derive strong constraints on the energy
                      scale of LIV $(E_ {QG})$ in the subluminal scenario for
                      linear and quadratic perturbations in the dispersion
                      relation of photons. For the case of linear perturbations,
                      the 95\% confidence level limits obtained are $E_{QG,1} >
                      3.6 × 10^{17}$ GeV using the temporal approach and
                      $E_{QG,1} > 2.6 × 10^{19}$ GeV using the spectral approach.
                      For the case of quadratic perturbations, the limits obtained
                      are $E_{QG,2} > 8.5 × 10^{10}$ GeV using the temporal
                      approach and $E_{QG,2} > 7.8 × 10^{11}$ GeV using the
                      spectral approach.},
