Topological order comes in different forms, and its classification and detection is an
important field of modern research. In this work, we show that the Disconnected …

Landau theory's implicit assumption that microscopic details cannot affect the global phases
has been challenged only recently in systems such as antiferromagnetic quantum spin …

It has been recently proven that new types of bulk local order can ensue due to frustrated
boundary condition, that is, periodic boundary conditions with an odd number of lattice sites …

Landau theory's implicit assumption that microscopic details cannot affect the system's
phases has been challenged only recently in systems such as antiferromagnetic quantum …

Ginzburg-Landau theory of continuous phase transitions implicitly assumes that microscopic
changes are negligible in determining the thermodynamic properties of the system. In this …

We find the asymptotic behaviors of Toeplitz determinants with symbols which are a sum of
two contributions: one analytical and non-zero function in an annulus around the unit circle …

We introduce the functional field integral approach to study the statistics of quantum work
under nonequilibrium conditions and derive the general formalism for a bilinear Hamiltonian …

Tackling the critical transverse Ising ring with or without ring frustration, we establish the
concept of nonlocality in a many-body system in the thermodynamic limit by calculating the …

We study a non-Hermitian version of XY closed chain with odd number of lattice sites. We
consider both anti-ferromagnetic coupling and also a symmetric non-collinear spin coupling …
