text: 'This paper establishes new connections between many-body quantum systems,
One-body Reduced Density Matrices Functional Theory (1RDMFT) and Optimal Transport
(OT), by interpreting the problem of computing the ground-state energy of a finite-dimensional
composite quantum system at positive temperature as a non-commutative entropy
regularized Optimal Transport problem. We develop a new approach to fully characterize
the dual-primal solutions in such non-commutative setting. The mathematical formalism
is particularly relevant in quantum chemistry: numerical realizations of the many-electron
ground-state energy can be computed via a non-commutative version of Sinkhorn
algorithm. Our approach allows to prove convergence and robustness of this algorithm,
which, to our best knowledge, were unknown even in the two marginal case. Our
methods are based on a priori estimates in the dual problem, which we believe
to be of independent interest. Finally, the above results are extended in 1RDMFT
setting, where bosonic or fermionic symmetry conditions are enforced on the problem.'

text: In this note we study the eigenvalue growth of infinite graphs with discrete
spectrum. We assume that the corresponding Dirichlet forms satisfy certain Sobolev-type
inequalities and that the total measure is finite. In this sense, the associated
operators on these graphs display similarities to elliptic operators on bounded
domains in the continuum. Specifically, we prove lower bounds on the eigenvalue
growth and show by examples that corresponding upper bounds cannot be established.

text: Bohnenblust–Hille inequalities for Boolean cubes have been proven with dimension-free
constants that grow subexponentially in the degree (Defant et al. in Math Ann
374(1):653–680, 2019). Such inequalities have found great applications in learning
low-degree Boolean functions (Eskenazis and Ivanisvili in Proceedings of the 54th
annual ACM SIGACT symposium on theory of computing, pp 203–207, 2022). Motivated
by learning quantum observables, a qubit analogue of Bohnenblust–Hille inequality
for Boolean cubes was recently conjectured in Rouzé et al. (Quantum Talagrand,
KKL and Friedgut’s theorems and the learnability of quantum Boolean functions,
2022. arXiv preprint arXiv:2209.07279). The conjecture was resolved in Huang et
al. (Learning to predict arbitrary quantum processes, 2022. arXiv preprint arXiv:2210.14894).
In this paper, we give a new proof of these Bohnenblust–Hille inequalities for
qubit system with constants that are dimension-free and of exponential growth
in the degree. As a consequence, we obtain a junta theorem for low-degree polynomials.
Using similar ideas, we also study learning problems of low degree quantum observables
and Bohr’s radius phenomenon on quantum Boolean cubes.

text: "In this paper, we prove the convexity of trace functionals (A,B,C)↦Tr|BpACq|s,\r\nfor
parameters (p, q, s) that are best possible, where B and C are any n-by-n positive-definite
matrices, and A is any n-by-n matrix. We also obtain the monotonicity versions
of trace functionals of this type. As applications, we extend some results in
Carlen et al. (Linear Algebra Appl 490:174–185, 2016), Hiai and Petz (Publ Res
Inst Math Sci 48(3):525-542, 2012) and resolve a conjecture in Al-Rashed and Zegarliński
(Infin Dimens Anal Quantum Probab Relat Top 17(4):1450029, 2014) in the matrix
setting. Other conjectures in Al-Rashed and Zegarliński (Infin Dimens Anal Quantum
Probab Relat Top 17(4):1450029, 2014) will also be discussed. We also show that
some related trace functionals are not concave in general. Such concavity results
were expected to hold in different problems."
