A wide range of dark matter candidates have been proposed and are actively being searched for in a large number of experiments, both at high (TeV) and low (sub meV) energies. One dark matter candidate, a deeply bound
Ising superconductivity, observed in NbSe_{2}and similar materials, has generated tremendous interest. Recently, attention was called to the possible role that spin fluctuations (SF) play in this phenomenon, in addition to the dominant electron–phonon coupling (EPC); the possibility of a predominantly triplet state was discussed and led to a conjecture of viable singlet–triplet Leggett oscillations. However, these hypotheses have not been put to a quantitative test. In this paper, we report first principle calculations of the EPC and also estimate coupling with SF, including full momentum dependence. We find that: (1) EPC is strongly anisotropic, largely coming from the

Abstract uuddss sexaquark, , with mass$$S$$ $S$ GeV (having the same quark content as the hypothesized Hdibaryon, but long lived) is particularly difficult to explore experimentally. In this paper, we propose a scheme in which such a state could be produced at rest through the formation of$$\sim 2$$ $\sim 2$ –$$\bar{p}$$ $\overline{p}$ He antiprotonic atoms and their annihilation into$$^3$$ ${}^{3}$ +$$S$$ $S$ , identified both through the unique tag of a$$K^+K^+\pi ^$$ ${K}^{+}{K}^{+}{\pi}^{}$ final state, as well as through full kinematic reconstruction of the final state recoiling against it.$$S=+2, Q=+1$$ $S=+2,Q=+1$ 
Abstract Spinflip (SF) methods applied to excitedstate approaches like the Bethe–Salpeter equation allow access to the excitation energies of openshell systems, such as molecules and defects in solids. The eigenstates of these solutions, however, are generally not eigenstates of the spin operator
. Even for simple cases where the excitation vector is expected to be, for example, a triplet state, the value of ${\hat{S}}^{2}$ may be found to differ from 2.00; this difference is called ‘spin contamination’. The expectation values $\u27e8{\hat{S}}^{2}\u27e9$ must be computed for each excitation vector, to assist with the characterization of the particular excitation and to determine the amount of spin contamination of the state. Our aim is to provide for the first time in the SF methods literature a comprehensive resource on the derivation of the formulas for $\u27e8{\hat{S}}^{2}\u27e9$ as well as its computational implementation. After a brief discussion of the theory of the SF Bethe–Salpeter equation (BSE) and some examples further illustrating the need for calculating $\u27e8{\hat{S}}^{2}\u27e9$ , we present the derivation for the general equation for computing $\u27e8{\hat{S}}^{2}\u27e9$ with the eigenvectors from an SFBSE calculation, how it is implemented in a Python script, and timing information on how this calculation scales with the size of the SFBSE Hamiltonian. $\u27e8{\hat{S}}^{2}\u27e9$ 
Abstract We perform pathintegral molecular dynamics (PIMD), ringpolymer MD (RPMD), and classical MD simulations of H
O and D$$_2$$ ${}_{2}$ O using the qTIP4P/F water model over a wide range of temperatures and pressures. The density$$_2$$ ${}_{2}$ , isothermal compressibility$$\rho (T)$$ $\rho \left(T\right)$ , and selfdiffusion coefficients$$\kappa _T(T)$$ ${\kappa}_{T}\left(T\right)$D (T ) of H O and D$$_2$$ ${}_{2}$ O are in excellent agreement with available experimental data; the isobaric heat capacity$$_2$$ ${}_{2}$ obtained from PIMD and MD simulations agree qualitatively well with the experiments. Some of these thermodynamic properties exhibit anomalous maxima upon isobaric cooling, consistent with recent experiments and with the possibility that H$$C_P(T)$$ ${C}_{P}\left(T\right)$ O and D$$_2$$ ${}_{2}$ O exhibit a liquidliquid critical point (LLCP) at low temperatures and positive pressures. The data from PIMD/MD for H$$_2$$ ${}_{2}$ O and D$$_2$$ ${}_{2}$ O can be fitted remarkably well using the TwoStateEquationofState (TSEOS). Using the TSEOS, we estimate that the LLCP for qTIP4P/F H$$_2$$ ${}_{2}$ O, from PIMD simulations, is located at$$_2$$ ${}_{2}$ MPa,$$P_c = 167 \pm 9$$ ${P}_{c}=167\pm 9$ K, and$$T_c = 159 \pm 6$$ ${T}_{c}=159\pm 6$ g/cm$$\rho _c = 1.02 \pm 0.01$$ ${\rho}_{c}=1.02\pm 0.01$ . Isotope substitution effects are important; the LLCP location in qTIP4P/F D$$^3$$ ${}^{3}$ O is estimated to be$$_2$$ ${}_{2}$ MPa,$$P_c = 176 \pm 4$$ ${P}_{c}=176\pm 4$ K, and$$T_c = 177 \pm 2$$ ${T}_{c}=177\pm 2$ g/cm$$\rho _c = 1.13 \pm 0.01$$ ${\rho}_{c}=1.13\pm 0.01$ . Interestingly, for the water model studied, differences in the LLCP location from PIMD and MD simulations suggest that nuclear quantum effects (i.e., atoms delocalization) play an important role in the thermodynamics of water around the LLCP (from the MD simulations of qTIP4P/F water,$$^3$$ ${}^{3}$ MPa,$$P_c = 203 \pm 4$$ ${P}_{c}=203\pm 4$ K, and$$T_c = 175 \pm 2$$ ${T}_{c}=175\pm 2$ g/cm$$\rho _c = 1.03 \pm 0.01$$ ${\rho}_{c}=1.03\pm 0.01$ ). Overall, our results strongly support the LLPT scenario to explain water anomalous behavior, independently of the fundamental differences between classical MD and PIMD techniques. The reported values of$$^3$$ ${}^{3}$ for D$$T_c$$ ${T}_{c}$ O and, particularly, H$$_2$$ ${}_{2}$ O suggest that improved water models are needed for the study of supercooled water.$$_2$$ ${}_{2}$ 
Abstract We continue the program of proving circuit lower bounds via circuit satisfiability algorithms. So far, this program has yielded several concrete results, proving that functions in
and other complexity classes do not have small circuits (in the worst case and/or on average) from various circuit classes$\mathsf {Quasi}\text {}\mathsf {NP} = \mathsf {NTIME}[n^{(\log n)^{O(1)}}]$ $\mathrm{Quasi}\mathrm{NP}=\mathrm{NTIME}\left[{n}^{{\left(\mathrm{log}n\right)}^{O\left(1\right)}}\right]$ , by showing that$\mathcal { C}$ $C$ admits nontrivial satisfiability and/or$\mathcal { C}$ $C$# SAT algorithms which beat exhaustive search by a minor amount. In this paper, we present a new strong lower bound consequence of having a nontrivial# SAT algorithm for a circuit class .

# SAT algorithms from the literature, one immediate corollary of our results is thatQ u a s i N P does not haveE M A J ∘A C C ^{0}∘T H R circuits of polynomial size, whereE M A J is the “exact majority” function, improving previous lower bounds againstA C C ^{0}[Williams JACM’14] andA C C ^{0}∘T H R [Williams STOC’14], [MurrayWilliams STOC’18]. This is the first nontrivial lower bound against such a circuit class. 
Abstract The interactions of kaons (K) and antikaons (
) with few nucleons (N) were studied so far using kaonic atom data and measurements of kaon production and interaction yields in nuclei. Some details of the threebody KNN and$$\mathrm {\overline{K}}$$ $\overline{K}$ NN dynamics are still not well understood, mainly due to the overlap with multinucleon interactions in nuclei. An alternative method to probe the dynamics of threebody systems with kaons is to study the final state interaction within triplet of particles emitted in pp collisions at the Large Hadron Collider, which are free from effects due to the presence of bound nucleons. This Letter reports the first femtoscopic study of p–p–K$$\mathrm {\overline{K}}$$ $\overline{K}$ and p–p–K$$^+$$ ${}^{+}$ correlations measured in highmultiplicity pp collisions at$$^$$ ${}^{}$ = 13 TeV by the ALICE Collaboration. The analysis shows that the measured p–p–K$$\sqrt{s}$$ $\sqrt{s}$ and p–p–K$$^+$$ ${}^{+}$ correlation functions can be interpreted in terms of pairwise interactions in the triplets, indicating that the dynamics of such systems is dominated by the twobody interactions without significant contributions from threebody effects or bound states.$$^$$ ${}^{}$
