Today's #arXivsummary: https://arxiv.org/abs/2311.06350 by Romen et. al. Authors investigate deconfined quantum critical points in the long-range, anisotropic Heisenberg chain. Model undergoes a continuous phase transition from valence bond solid to an antiferromagnet. Long-range interactions are irrelevant & transition is well described by a double frequency sine-Gordon model. #CondMat #arXiv_2311_06350

Today's #arXivsummary: https://arxiv.org/abs/2311.04266 by Radzihovsky. Author points out a simple and generic mechanism for a thermally-driven reentrant supersolidity. Mechanism reduces to a re-enterant low-temperature normal-superfluid transition. #CondMat #arXiv_2311_04266

Today's #arXivsummary: https://arxiv.org/abs/2306.04682 by Singh et. al. Authors show that ensembles of initial states in anisotropic integrable spin chains with quasi-long range correlations lead to superdiffusive spin transport with a tunable dynamical exponent. Theoretical prediction provided for dynamical critical exponent. #CondMat #StatMech #arXiv_2306_04682

Today's #arXivsummary: https://arxiv.org/abs/2306.03142 by Leo Radzihovsky. Chapter to be published in World Scientific, as "50 years of the renormalization group", dedicated to the memory of Michael E. Fisher. Novel ordered states of “critical matter” reviewed which exhibit strongly fluctuating universal power-law orders, controlled by an infrared attractive, non-Gaussian fixed point. #CondMat #StatMech #arXiv_2306_03142

Today's #arXivsummary: https://arxiv.org/abs/2304.03818 by Kassan-Ogly & Zarubin. Authors utilize a Kramers-Wannier transfer matrix method to study the frustration properties of the Ising model on a decorated triangular lattice with an arbitrary number of decorating spins on all lattice bonds. Entropy, heat capacity, and spontaneous magnetization found. #CondMat #StatMech #arXiv_2304_03818

Today's #arXivsummary: https://arxiv.org/abs/2303.14140 by Iubini et. al. Authors study nonequilibrium steady states of a one-dimensional stochastic model. When steadily maintained out-of-equilibrium, coupled transport exhibited which is studied within linear response theory. Onsager coefficients satisfy an exact scaling relationship. #arXivsummary #CondMat #StatMech

Today's #arXivsummary: https://arxiv.org/abs/2303.09573 by Stahl et. al. Authors examine the hydrodynamics of systems with spontaneously broken multipolar symmetries using systematic effective field theory. In absence of any SSB, quartic subdiffusion found. With both charge and dipole symmetries broken, quadratically propagating (and quartically subdiffusing) mode found. #CondMat #StatMech #arXiv_2303_09573

Today's #arXivsummary: https://arxiv.org/abs/2303.08835 by Ouvry & Polychronakos. Authors introduce inclusion statistics, where particles tend to coalesce more than ordinary bosons. Lowest space dimension in which particles condense in absence of potentials is d=2. Critical temperature increases with stronger inclusion. #CondMat #StatMech #arXiv_2303_08835

Today's #arXivsummary: https://arxiv.org/abs/2303.03448 by Cipolloni & Kudler-Flam. Authors investigate the extent to which the eigenstate thermalization hypothesis holds for non-Hermitian many-body systems; fluctuations btw eigenstates is of equal order to average (indicating no thermalization). Shown in non-Hermitian Sachdev-Ye-Kitaev model and others. #CondMat #StatMech #arXiv_2303_03448

Today's #arXivsummary: https://arxiv.org/abs/2303.02171 by Haldar et. al. Authors perform exact microscopic study of a complex CFT (CCFT) in the two-dimensional O(n) loop model. Real & imaginary parts of central charge & scaling dimensions extracted. CCFT interpreted as a liquid-gas critical point at the end of a first-order transition line. #CondMat #StatMech #arXiv_2303_02171

Today's #arXivsummary: https://arxiv.org/abs/2302.12820 by Fava et. al. Authors derive field theory descriptions for measurement-induced phase transitions in free fermion systems. Dynamics mapped to imaginary time evolution of an effective spin chain; phase diagram shows transitions out of the nontrivial phase. #CondMat #StatMech #arXiv_2302_12820

Today's #arXivsummary: https://arxiv.org/abs/2301.13218 by Khasseh et. al. Authors introduce an alternative indicator for quantum many-body integrability and chaos based on the statistics of eigenstates by means of nearest-neighbor subsystem trace
distances. Indicator signals the expected quantum many-body integrability. #CondMat #StatMech #arXiv_2301_13218

Today's #arXivsummary: https://arxiv.org/abs/2211.14389 by Veríssimo et. al. Authors investigate the interplay between dissipation and symmetry-protected topological order in a dissipative Spin-1 Affleck-Kennedy-Lieb-Tasaki model via tensor network techniques. For time-reversal symmetric dissipation, topological signatures remain. #CondMat #StrEl #OpenSystems #TensorNetworks #arXiv_2211_14389

Today's #arXivsummary: https://arxiv.org/abs/2211.09134 by Winer & Swingle. Authors examine the spectral form factor (SFF) for hydrodynamic system w/sound pole. Log of hydro enhancement closely related to SFF. Interference in the emergent hydrodynamic SFF formalism explored. #CondMat #StatMech #arXiv_2211_09134
