A variational approach for many-body systems at finite temperature
Tao Shi, Eugene Demler, J. Ignacio Cirac
We introduce a non-linear differential flow equation for density matrices that provides a monotonic decrease of the free energy and reaches a fixed point at the Gibbs thermal state…
Markovianity of an emitter coupled to a structured spin chain bath
J. Roos, J. I. Cirac, M. C. Bañuls
We analyze the dynamics of a spin 1/2 subsystem coupled to a spin chain. We simulate numerically the full quantum many-body system for various sets of parameters and initial states…
Sideband-resolved resonator electromechanics on the single-photon level based on a nonlinear Josephson inductance
Philip Schmidt, Mohammad T. Amawi, Stefan Pogorzalek +4
Light-matter interaction in optomechanical systems is the foundation for ultra-sensitive detection schemes [1,2] as well as the generation of phononic and photonic quantum states […
Gapped spin liquid in the breathing kagome Heisenberg antiferromagnet
Mohsin Iqbal, Didier Poilblanc, Norbert Schuch
We investigate the spin-1/2 Heisenberg antiferromagnet on the kagome lattice with breathing anisotropy (i.e. with weak and strong triangular units), constructing an improved simple…
Fermionic tensor networks for higher order topological insulators from charge pumping
Anna Hackenbroich, B. Andrei Bernevig, Norbert Schuch +1
We apply the charge pumping argument to fermionic tensor network representations of d-dimensional topological insulators (TIs) to obtain tensor network states for (d+1)-dimensional…
Phase structure and real-time dynamics of the massive Thirring model in 1+1 dimensions using the tensor-network method
Mari Carmen Bañuls, Krzysztof Cichy, Hao-Ti Hung +4
We present concluding results from our study for zero-temperature phase structure of the massive Thirring model in 1+1 dimensions with staggered regularisation. Employing the metho…
Fractional corner charges in a 2D super-lattice Bose-Hubbard model
Julian Bibo, Izabella Lovas, Yizhi You +2
We study a two dimensional super-lattice Bose-Hubbard model with alternating hoppings in the limit of strong on-site interactions. We evaluate the phase diagram of the model around…
Theory of exciton-electron scattering in atomically thin semiconductors
Christian Fey, Peter Schmelcher, Atac Imamoglu +1
The realization of mixtures of excitons and charge carriers in van-der-Waals materials presents a new frontier for the study of the many-body physics of strongly interacting Bose-F…
Intermolecular forces and correlations mediated by a phonon bath
Xiang Li, Enderalp Yakaboylu, Giacomo Bighin +3
Inspired by the possibility to experimentally manipulate and enhance chemical reactivity in helium nanodroplets, we investigate the effective interaction and the resulting correlat…
The Quantum Random Energy Model as a Limit of p-Spin Interactions
Chokri Manai, Simone Warzel
We consider the free energy of a mean-field quantum spin glass described by a -spin interaction and a transversal magnetic field. Recent rigorous results for the case $ p= \in…
Wigner Crystals in Two-Dimensional Transition-Metal Dichalcogenides: Spin Physics and Readout
Johannes Knörzer, Martin J. A. Schuetz, Geza Giedke +5
Wigner crystals are prime candidates for the realization of regular electron lattices under minimal requirements on external control and electronics. However, several technical cha…
Tune-out and magic wavelengths for ground-state NaK molecules
Roman Bause, Ming Li, Andreas Schindewolf +5
We demonstrate a versatile, rotational-state dependent trapping scheme for the ground and first excited rotational states of NaK molecules. Close to the rotational ma…
State-dependent optical lattices for the strontium optical qubit
A. Heinz, A. J. Park, N. Šantić +5
We demonstrate state-dependent optical lattices for the Sr optical qubit at the tune-out wavelength for its ground state. We tightly trap excited state atoms while suppressing the…

Mari Carmen Banuls, Michal P. Heller, Karl Jansen +2
One of the most interesting directions in theoretical high-energy and condensed-matter physics is understanding dynamical properties of collective states of quantum field theories.…
On the excess charge of a relativistic statistical model of molecules with an inhomogeneity correction
Hongshuo Chen, Heinz Siedentop
We show that the molecular relativistic Thomas-Fermi-Weizsäcker functional consisting of atoms of atomic numbers has a minimizer, if the particle number is constr…
Distinguishing localization from chaos: challenges in finite-size systems
D. A. Abanin, J. H. Bardarson, G. De Tomasi +7
We re-examine attempts to study the many-body localization transition using measures that are physically natural on the ergodic/quantum chaotic regime of the phase diagram. Using s…
From Luttinger liquids to Luttinger droplets via higher-order bosonization identities
Sebastian Huber, Marcus Kollar
We derive generalized Kronig identities expressing quadratic fermionic terms including momentum transfer to bosonic operators and use them to obtain the exact solution for one-dime…
Exact dynamics in dual-unitary quantum circuits
Lorenzo Piroli, Bruno Bertini, J. Ignacio Cirac +1
We consider the class of dual-unitary quantum circuits in dimensions and introduce a notion of ``solvable'' matrix product states (MPSs), defined by a specific condition whic…
Quantum phases of a one-dimensional Majorana-Bose-Hubbard model
Ananda Roy, Johannes Hauschild, Frank Pollmann
Majorana zero modes (MZM-s) occurring at the edges of a 1D, p-wave, spinless superconductor, in absence of fluctuations of the phase of the superconducting order parameter, are qui…
