The fate of an isolated quantum many-body system has attracted much attention in the past decade. One of the most important issues is whether such a system can reach thermalization under its own dynam...

A ripe apple falling from a tree has inspired Sir Isaac Newton to formulate a theory that describes the motion of objects subject to a force. Newton’s equations of motion tell us that a moving body ke...

It is shown that topologically stable cosmic strings can, in fact, appear to end or to break, even in theories without monopoles. This can occur whenever the spatial topology of the universe is nontri...
Anthropic considerations in multiple-domain theories and the scale of electroweak symmetry breaking

One of the puzzles of the Standard Model is why the mass parameter which determines the scale of the Weak interactions is closer to the scale of Quantum Chromodymanics (QCD) than to the Grand Unificat...
Breaking diffeomorphism invariance and tests for the emergence of gravity
General relativity violates diffeomorphism invariance disrupting sex match the test parameters Newton formalism

If general relativity is an emergent phenomenon, there may be small violations of diffeomorphism invariance. We propose a phenomenology of perturbatively small violations of general relativity by the ...
Effect of Position-dependent Mass on Dynamical Breaking of Type B and Type X_2 N-fold Supersymmetry

We investigate effect of position-dependent mass profiles on dynamical breaking of N-fold supersymmetry in several type B and type X_2 models. We find that N-fold supersymmetry in rational potentials ...

Abstract: We demonstrate the presence of parity-time (PT) symmetry for the non-Hermitian two-state Hamiltonian of a dissipative microwave billiard in the vicinity of an exceptional point (EP). The sha...

We propose a conjecture about the detailed structure of the conformal symmetry breaking term in the QCD generalization of Crewther relation and demonstrate its validity at the $\alpha_s^4$-level. We c...

We discuss the possibility of finding scenarios within type IIB string theory compactified on Calabi-Yau orientifolds with fluxes, for realizing gauge mediated supersymmetry breaking. We find that whi...

PT-symmetric systems can have a real spectrum even when their Hamiltonian is non-hermitian, but develop a complex spectrum when the degree of non-hermiticity increases. Here we utilize random-matrix t...

Nematicity, defined as broken rotational symmetry, has recently been observed in the competing phases in proximity to the superconducting phase in the high TC cuprates (1-2). Similarly, the new iron-b...

We address in detail the issue of possible resonances in the massive modes on a brane without
re ection symmetry. After identifying a set of solvability conditions, we show explicitly how the modes o...

We show that an interacting spin-0 field on a de Sitter space backgroundwill break the underlying de Sitter symmetry. This is done first for a (1+1) de Sitter space where a boson-fermion correspondenc...
